GitHub Copilot vs Microsoft Copilot: Which AI Tool Should You Choose?

QA v1.0 — 2026-05-24 KST. content_status = qa_passed. Generated from templates/comparison-page-template.md and promoted after an independent Section B walk-through of qa/adsense-seo-quality-gate.md. Meta description (≤ 155 chars): GitHub Copilot is the AI pair-programmer for IDEs and GitHub; Microsoft Copilot is Microsoft's multi-SKU 365 AI — here is the choice.

Quick recommendation

• Choose GitHub Copilot if: the higher-value job is in-editor code completion, code chat, agent-mode coding features, and pull-request assistance for developers whose repos and review workflow already live on GitHub. The product surface is editor extensions (VS Code, JetBrains IDEs, Visual Studio, Xcode, Neovim, Eclipse, Raycast, SQL Server Management Studio, Zed — plus Vim and Azure Data Studio referenced in supporting text) and the GitHub web surface itself (Copilot Chat, PR assistance, Copilot CLI). Pricing read from github.com/features/copilot/plans on 2026-05-22 KST: Free at $0 with 50 agent/chat requests and 2,000 completions per month and access to a listed model set (Haiku 4.5, GPT-5 mini, and others), Pro at $10/user/month, Pro+ at $39/user/month, plus Business and Enterprise listed at Contact Sales. The buying motion is sized to developer headcount, not to the full M365 employee population.
• Choose Microsoft Copilot if: your organization already runs on Microsoft 365 (Word, Excel, Outlook, PowerPoint, Teams) and Windows, and you want the AI to appear as a native surface inside those apps — with admin tooling (Copilot Analytics, SharePoint Advanced Management, sensitivity labels), Microsoft Graph connectors (100+), Entra identity, and the rest of the Microsoft procurement story already in place. Accept that "Microsoft Copilot" is an umbrella brand spanning multiple SKUs (consumer Copilot at copilot.microsoft.com, Copilot Pro, Microsoft 365 Copilot Chat, Microsoft 365 Copilot Business, plus adjacent Copilots like Microsoft Security Copilot, Microsoft Copilot Studio, Copilot in Azure, and Copilot in Power Apps sold separately) and that the per-user price depends on which SKU you actually intend to buy.
• Consider another option if: you want an AI-first editor built around codebase chat and multi-file edits (Cursor is the AI-first editor), a self-hosted or private-model coding assistant for license-sensitive work (Tabnine), a browser-based prototyping environment that wraps the editor, runtime, agent, and hosting in one tab (Replit AI), a careful general-purpose chat assistant for long-context reading and writing (Claude), an in-suite assistant for Google Workspace rather than Microsoft 365 (Gemini), an in-workspace AI layer for teams already on Notion (Notion AI), an in-place writing layer that follows a writer across many apps (Grammarly (AI)), or a templated brand-voiced marketing-content workflow (Jasper).

Short answer

GitHub Copilot and Microsoft Copilot are both Microsoft brands and they both contain the word "Copilot", and that single fact is the most common source of buyer confusion in this space. They are not the same product, they are not the same SKU, and they are not licensed or entitled together. One license does not cover the other.

GitHub Copilot is GitHub's AI pair-programming assistant. It lives primarily inside supported IDEs (VS Code, JetBrains IDEs, Visual Studio, Neovim, Xcode, Zed, Eclipse, Raycast, SQL Server Management Studio, and others enumerated on the official plans page) and inside GitHub itself, where it offers code completion, chat, agent-mode coding features, pull-request assistance, and a CLI. The buyer is an individual developer or an engineering team; the procurement question is sized to developer seats.

Microsoft Copilot is Microsoft's umbrella brand for AI assistants across its productivity and platform surfaces. It is not a single product — the same name covers, at minimum, the free consumer Copilot at copilot.microsoft.com (plus the free Microsoft Copilot app and the Windows/Edge integrations), Microsoft Copilot Pro (consumer paid), Microsoft 365 Copilot Chat (included at no additional cost for users with eligible Microsoft 365 subscriptions), and Microsoft 365 Copilot Business (a paid per-user add-on to Microsoft 365 that brings AI inside Word, Excel, Outlook, PowerPoint, and Teams with admin tooling, Microsoft Graph connectors, and Copilot Notebooks). Adjacent Copilots — Microsoft Security Copilot, Microsoft Copilot Studio, Copilot in Azure, Copilot in Power Apps, and indeed GitHub Copilot — are sold and entitled separately. The buyer is usually IT / workplace productivity, and the procurement question is sized to the population that lives in Microsoft 365.

That difference is most of the decision. If the job is shipping code every day inside an editor, on a repo that lives on GitHub, GitHub Copilot is the relevant product. If the job is drafting in Word, summarizing in Outlook, building formulas in Excel, generating slides in PowerPoint, or recapping a Teams meeting, Microsoft 365 Copilot Business is the relevant product. The two do not overlap on either of those primary surfaces. There is no consumer or M365 Microsoft Copilot SKU that provides in-IDE completions across VS Code / JetBrains / Visual Studio in the way GitHub Copilot does, and GitHub Copilot does not draft your slide deck inside PowerPoint, recap a Teams meeting, or build a Microsoft Graph–grounded answer across a SharePoint tenant.

A pricing caveat applies on both sides. GitHub Copilot's plan structure was read from github.com/features/copilot/plans on 2026-05-22 KST: Free at $0 with 50 agent/chat requests and 2,000 completions per month and access to a listed model set (Haiku 4.5, GPT-5 mini, and others), plus the Copilot CLI and no credit card required; Pro at $10/user/month; Pro+ at $39/user/month with additional model access and quotas; Business and Enterprise listed with Contact Sales pricing in the section read. Microsoft 365 Copilot Business USD pricing was visible on microsoft.com/en-us/microsoft-365/copilot/business on 2026-05-23 KST at $18/user/month with annual commitment paid yearly, $18.90/user/month with annual commitment paid monthly, or $25.20/user/month on a monthly commitment, each requiring a separate qualifying Microsoft 365 license. The free consumer Microsoft Copilot at copilot.microsoft.com and Microsoft 365 Copilot Chat (included at no additional cost for users with eligible Microsoft 365 subscriptions) were also confirmed in the same fetch pass. Consumer Microsoft Copilot Pro USD pricing was not visible during the 2026-05-23 fetch — multiple Copilot Pro URL variants returned 403, 404, or timeout — and is routed to the official Microsoft site rather than asserted on this page. GitHub Copilot Business / Enterprise dollar amounts and region-specific pricing were similarly not in scope of the 2026-05-22 plans-page fetch and are routed to "verify on official site". Both vendors have moved SKUs, features, and quotas between releases; reconfirm before any pricing-sensitive commitment.

Comparison table

Use-case based choice

For writing and editing

This is the use case where the two products are genuinely not in the same conversation, and naming the difference clearly is most of the value of this page.

GitHub Copilot is not a general writing assistant. Its writing-adjacent surface is comments, commit messages, PR descriptions, and code-explanation prose generated inside the IDE or on GitHub itself. The Free tier (50 agent/chat requests and 2,000 completions per month, no credit card required) is a real evaluation surface for an individual developer; Pro at $10/user/month is the standard individual seat; Pro+ at $39/user/month layers on more model access and higher quotas. Asking Copilot Chat to clean up a commit message or to summarize a PR is a fine secondary use, but the product is not built for a non-developer who needs help drafting emails, memos, slide decks, or external documents.

**Microsoft Copilot in the Microsoft 365 Copilot Business SKU is the right fit when the writing surface is Word, Outlook, or another Microsoft 365 app, and the job is more than "tighten this sentence".** The 2026-05-23 read of microsoft.com/en-us/microsoft-365/copilot/business lists drafting in Word, summarizing in Outlook, generating slides in PowerPoint, building formulas and analyzing data in Excel, and recapping meetings in Teams as in-app capabilities, plus AI-generated images, posters, banners, and videos and Copilot Notebooks for grouping work artifacts. The free consumer Copilot at copilot.microsoft.com and the free Microsoft Copilot app give a no-cost on-ramp for individual writers in the consumer surface; Microsoft 365 Copilot Chat (included at no additional cost for users with eligible Microsoft 365 subscriptions) adds the in-365 chat surface without an additional per-user fee; the paid Microsoft 365 Copilot Business SKU at $18 / $18.90 / $25.20 per user/month (depending on commitment) is where the full in-365-app surface is actually entitled, on top of a separate qualifying Microsoft 365 license.

Both can co-exist on a single organization's seats without duplicating the same job. Many engineering-heavy companies pay for both: Microsoft 365 Copilot Business for the in-Word / in-Outlook / in-PowerPoint productivity work that non-developer roles do, and GitHub Copilot for the in-IDE coding work that developer roles do. The cost stack adds rather than substitutes; the line items belong to different headcount populations.

For long, analytical, structured writing — multi-page memos, research summaries, contract reviews, RFCs that demand careful reasoning across many inputs — neither product is the natural pick. GitHub Copilot is not pitched for it at all; Microsoft Copilot inside Word can draft and rewrite but the long-context analytical job is closer to what a dedicated chat assistant like Claude is positioned for. The practical pattern is to use a chat assistant for the heavy draft and bring the result back into the user's normal surface — Word + Microsoft Copilot to publish, send, and review; the IDE + GitHub Copilot to do the same for code.

For in-place writing assistance that follows a writer across many apps — grammar, clarity, tone, and rewrite suggestions in Gmail, Google Docs, Slack, Salesforce notes, LinkedIn posts, browser form fields, and mobile keyboards — neither product covers the surface either. Grammarly (AI) is the in-place writing layer that follows a writer between apps; see GitHub Copilot vs Grammarly (AI) and Grammarly (AI) vs Microsoft Copilot for those framings.

The honest split for writing-heavy use cases:

• If the writing surface is the IDE or GitHub itself (commit messages, PR descriptions, code-explanation comments), GitHub Copilot covers it as a side effect of being there. Free at $0 is enough to evaluate; Pro at $10/user/month is the standard individual seat.
• If the writing surface is Word, Outlook, PowerPoint, or Teams, Microsoft 365 Copilot Business at $18–$25.20/user/month depending on commitment is the in-365 answer, on top of a separate qualifying Microsoft 365 license. The free consumer Copilot and the no-additional-cost M365 Copilot Chat are the evaluation surfaces.
• Treat AI-drafted content as a proposal that needs human review, especially for legal, medical, financial, or HR-sensitive content. Neither tool's draft is a finished deliverable.

For coding and technical work

This is where GitHub Copilot is on the table and Microsoft Copilot, in its consumer and Microsoft 365 SKUs, is not.

GitHub Copilot is the in-IDE coding assistant from Microsoft. It puts inline completions inside supported IDEs (VS Code, JetBrains IDEs, Visual Studio, Neovim, Xcode, Zed, Eclipse, Raycast, SQL Server Management Studio, and others enumerated on the plans page; Vim and Azure Data Studio also referenced in supporting text). Copilot Chat lives both inside the IDE and on GitHub itself for explanations, refactors, test generation, and code Q&A. GitHub-side features include pull-request assistance and code-review aids that a chat-only assistant cannot easily replicate, plus the Copilot CLI for terminal-side work. Free at $0 (50 agent/chat requests and 2,000 completions per month, listed model set, Copilot CLI, no credit card required) is a meaningful evaluation surface; Pro at $10/user/month is the standard individual seat; Pro+ at $39/user/month adds broader model access and higher quotas; Business and Enterprise (Contact Sales on the 2026-05-22 plans-page read) are the team and enterprise tiers where seat management, admin controls, and enterprise data-handling commitments live.

Microsoft Copilot in its consumer and Microsoft 365 SKUs is not the in-IDE coding assistant. The Microsoft 365 Copilot Business SKU lists custom agents with advanced reasoning, AI-powered search across work data, and Copilot Notebooks — useful around a developer's workflow (search a Microsoft 365 tenant for prior design docs, group meeting notes and decisions into a Notebook, ask grounded questions across SharePoint and OneDrive), but none of that puts completions or chat inside VS Code or JetBrains. The free consumer Microsoft Copilot at copilot.microsoft.com can answer coding questions as a general chat assistant, but it does not wrap the editor or the repo. Buying Microsoft 365 Copilot Business does not entitle a developer to GitHub Copilot, and vice versa.

The honest split for developers:

• If the single most important workflow is in-editor completions, chat on GitHub-hosted repos, PR assistance, and a Copilot CLI alongside the rest of the GitHub surface, GitHub Copilot is the answer. The Free tier alone is enough to evaluate without a credit card; Pro at $10/user/month is the standard individual seat.
• Microsoft Copilot is not the same product as GitHub Copilot even though both are Microsoft brands; they are licensed and entitled separately. If a developer also needs the in-365 productivity AI (drafting in Word, recapping in Teams, building formulas in Excel) and the organization already runs on Microsoft 365, those are two separate per-user line items.
• If your team writes a lot of prose around code — release notes, design docs, RFCs, internal updates, PR descriptions, customer-facing changelogs — Microsoft 365 Copilot Business inside Word and Outlook can be a useful prose helper on top of the in-IDE coding assistant your team already pays for, but it is not a substitute for the in-IDE assistant.
• For an AI-first editor (a VS Code fork built around AI workflows, multi-file edits, and codebase chat), look at Cursor — see Cursor vs GitHub Copilot. For a browser-based prototyping environment that wraps the editor, runtime, agent, and hosting in one tab, look at Replit AI — see GitHub Copilot vs Replit AI.

None of this is a benchmark claim. Coding quality varies across languages, tasks, model versions, and prompt shapes, and both products' underlying model lineups change frequently. Treat any "X is better at code than Y" headline as out-of-date by the time you read it; do your own evaluation on the work you actually ship.

For research and fact-checking

Neither product is a citation-first answer engine; both produce confident text that needs to be checked against a primary source before it ships in a document or a code comment. They fail differently because they draw on different content and live on different surfaces.

GitHub Copilot's research-style strength is code-local. Inside the IDE, Copilot Chat can explain unfamiliar code, walk through a function's behavior, propose a refactor, or generate a test scaffold — useful for "research" in the sense of understanding what a codebase actually does. On GitHub itself, Copilot can summarize a PR or surface change context. None of this is general-purpose research across the web or across a corporate document tenant; that is outside the surface Copilot wraps. For general fact-finding about the world, a dedicated AI answer engine is closer to the job than either of these two.

Microsoft Copilot's research-style strength, in the paid Microsoft 365 Copilot Business SKU, is grounded chat across your organization's work data via Microsoft Graph (100+ connectors). That is a genuinely distinctive offer when the organization already has a sprawl of documents, emails, intranet content, and other knowledge inside Microsoft 365 and SharePoint. The free consumer Copilot at copilot.microsoft.com is closer to a general-purpose chat assistant with web grounding — useful for ad-hoc lookups but not the same internal-search-across-tenant story as the paid Business SKU. For organizations with serious internal-research needs that span email, SharePoint, OneDrive, and Teams content, Microsoft Graph connectors are the differentiator.

For research specifically:

• For code-local research (understanding a function, recovering the intent of an unfamiliar codebase, generating a test scaffold), GitHub Copilot in the IDE is the directly marketed answer between these two.
• For internal-document search and grounded chat across a Microsoft 365 tenant, Microsoft 365 Copilot Business with Microsoft Graph connectors is the directly marketed answer.
• For long-document reading and analytical reasoning across PDFs, contracts, or research papers you already have in hand, a dedicated chat assistant like Claude is closer to that job than either of these two.
• For citation-first web research with inline citations from many sources, a dedicated AI answer engine is closer to that job than either of these two.

Either tool's generated claims need to be verified against a primary source before they ship in a document or a code comment. Treat AI-generated summaries and answers as proposals, not as finished work.

For teams or businesses

The team buying decision is the bulk of the practical choice between these two products, and it splits cleanly because they answer different procurement questions and are pitched to different buyers inside an organization. The most common procurement mistake here is treating "Copilot" as a single brand and assuming one license covers both jobs. It does not.

GitHub Copilot for teams is the product's natural buying surface. The 2026-05-22 page-body read of github.com/features/copilot/plans showed Pro at $10/user/month and Pro+ at $39/user/month as the public per-user prices, with Business and Enterprise listed on the same page at Contact Sales for the section read. Business and Enterprise are where seat management, admin controls, and enterprise data-handling commitments live; verify the specifics with GitHub before adopting at scale. The buyer is engineering leadership or developer-tools procurement; the seat math is sized to developer headcount, not to the full M365 employee population. A 500-person company with 60 developers might buy 60 Copilot Business seats — not 500.

Microsoft Copilot for teams is structurally more complicated, because the same brand spans multiple SKUs with different entitlements and prices. Microsoft 365 Copilot Business is the headline per-user paid SKU at $18/user/month with annual commitment paid yearly, $18.90/user/month with annual commitment paid monthly, or $25.20/user/month on a monthly commitment, as read directly from microsoft.com/en-us/microsoft-365/copilot/business on 2026-05-23 KST. Crucially, that price is the add-on on top of a separate qualifying Microsoft 365 license; the headline number is not the total cost of running Copilot for an organization. Microsoft 365 Copilot Chat is included at no additional cost for users with eligible Microsoft 365 subscriptions and is the right surface to look at for a lower-feature on-ramp before scaling to Business. Microsoft 365 Copilot Enterprise SKU pricing and education SKU pricing were not in scope of the 2026-05-23 fetch and should be confirmed through Microsoft's enterprise procurement channels and your account team. Consumer Microsoft Copilot Pro pricing was not visible on the same date (multiple Copilot Pro URL variants returned 403/404/timeout) and should be verified directly on Microsoft's official Copilot Pro page. The buyer is usually IT / workplace productivity, not engineering, and the per-user math is sized to the in-365 employee population — the 500-person company in the example above might buy 500 Microsoft 365 Copilot Business seats and not 60.

The choice is not "which is cheaper per seat". GitHub Copilot Pro at $10/user/month and Microsoft 365 Copilot Business at $18–$25.20/user/month look like spreadsheet-comparable lines, but they are buying different things. GitHub Copilot Pro buys an in-IDE coding assistant for one developer seat. Microsoft 365 Copilot Business buys the AI surface inside Word, Excel, Outlook, PowerPoint, and Teams plus admin tooling (Copilot Analytics, SharePoint Advanced Management, sensitivity labels, Entra identity) plus AI search across work data via Microsoft Graph (100+ connectors) plus AI-generated images / posters / banners / videos and Copilot Notebooks — and requires you to already be paying for a qualifying Microsoft 365 license per seat. The like-for-like comparison is not "AI for $10 vs $18" but "in-IDE coding assistant sized to developer seats vs in-Microsoft-365 productivity AI suite sized to the whole knowledge-worker population", and both answers can be "yes" inside the same organization.

For an engineering-heavy team whose primary AI need is in-editor coding, GitHub Copilot is the natural per-developer buy and Microsoft Copilot's in-365 advantage is mostly not exercised (developers spend their day in VS Code or JetBrains, not in Word). For a knowledge-work organization standardized on Microsoft 365 whose primary AI need is in-Word / in-Outlook / in-Excel productivity, Microsoft 365 Copilot Business is the natural per-user buy. For most real organizations, both — sized to the populations that use each surface — is the expected outcome, not "pick one".

Several adjacent Copilots — Microsoft Security Copilot, Microsoft Copilot Studio, Copilot in Azure, Copilot in Power Apps — are sold and entitled separately and are not covered by a Microsoft Copilot license. If your team needs AI in security operations, that is Microsoft Security Copilot; if your team is building custom agents, that is Microsoft Copilot Studio; and so on. The "Microsoft Copilot" brand does not mean a single licensing surface.

Admin/SSO availability, data-handling for AI inputs and outputs, code-snippet retention policy per tier (GitHub Copilot) and document-content retention policy per tier (Microsoft Copilot), model-training opt-outs, region and currency, IDE feature parity (GitHub Copilot) and feature-by-tier matrix (Microsoft Copilot) should all be confirmed on each vendor's official documentation before procurement. Treat each vendor's published policy as the only authoritative source on what is and is not used for model training or improvement.

Pricing and plan caveats

• GitHub Copilot: the page-body read of github.com/features/copilot/plans on 2026-05-22 KST showed Free at $0 with 50 agent/chat requests and 2,000 completions per month, access to a listed model set (Haiku 4.5, GPT-5 mini, and others), Copilot CLI, no credit card required; Pro at $10/user/month; Pro+ at $39/user/month with additional model access and quotas enumerated on the plans page; Business and Enterprise on Contact Sales pricing in the section read. Business/Enterprise dollar amounts and region-specific pricing were not in scope of that fetch and should be confirmed directly with GitHub before being quoted.
• Microsoft Copilot: the 2026-05-23 page-body read of microsoft.com/en-us/microsoft-365/copilot/business confirmed Microsoft 365 Copilot Business at $18/user/month with annual commitment paid yearly, $18.90/user/month with annual commitment paid monthly, and $25.20/user/month on a monthly commitment, each requiring a separate qualifying Microsoft 365 license. The 2026-05-23 read of microsoft.com/en-us/microsoft-copilot confirmed the free consumer Copilot at copilot.microsoft.com plus a free Microsoft Copilot app, and Microsoft 365 Copilot Chat at no additional cost for users with eligible Microsoft 365 subscriptions. Consumer Microsoft Copilot Pro USD pricing was not visible during the same fetch pass (multiple Copilot Pro URLs returned 403/404/timeout); Copilot Pro pricing should be verified directly on Microsoft's official Copilot Pro store/landing page before being quoted. Microsoft 365 Copilot Enterprise SKU and education SKU pricing were not in scope of the Business page fetch and should be confirmed through Microsoft's enterprise procurement surfaces.

Both vendors have moved SKUs, features, and quotas between releases. Treat the structural facts and numbers above as recent (May 2026) reference points, not as long-term guarantees. Re-verify before quoting either page in a high-stakes decision.

Who should choose GitHub Copilot

• Your developers ship code every day in an IDE, your repos and review process live on GitHub, and you want AI completion, chat, agent-mode features, and pull-request assistance to appear inside the editor and code host you already use.
• You want a Free tier you can evaluate without a credit card (50 agent/chat requests and 2,000 completions per month, plus the Copilot CLI and the listed model set) before standing up paid seats.
• You want the per-developer math to be straightforward at the individual seat ($10/user/month Pro, $39/user/month Pro+) and to scale into Business / Enterprise on Contact Sales when admin controls and enterprise data-handling commitments become binding.
• You want native integration with GitHub's repo, PR, and code-review object graph — a chat-only assistant cannot wrap that surface, and that integration is the unique offer.
• You accept that GitHub Copilot is sold separately from Microsoft Copilot and does not entitle you to the in-Word / in-Outlook / in-Excel productivity AI of Microsoft 365 Copilot Business, and vice versa.

Who should choose Microsoft Copilot

• Your organization already standardizes on Microsoft 365 and Windows; your users live in Word, Outlook, Excel, PowerPoint, and Teams every day; and the procurement, identity (Microsoft Entra), and compliance posture is easier to satisfy through Microsoft contracts than through a new vendor.
• You want admin tooling (Copilot Analytics, SharePoint Advanced Management, sensitivity labels) for AI adoption alongside the AI itself, and you want Entra-backed identity and conditional access in place from day one.
• Your team needs internal-document search across a Microsoft 365 tenant via Microsoft Graph (100+ connectors), grounded chat across that work data, custom agents with advanced reasoning, and Copilot Notebooks inside the Microsoft 365 Copilot Business SKU.
• A no-additional-cost evaluation surface matters to you: Microsoft 365 Copilot Chat is included for users with eligible Microsoft 365 subscriptions, so you can pilot the in-365 chat surface before committing to per-user Business pricing at $18 / $18.90 / $25.20 per user/month.
• You want AI-generated images, posters, banners, and videos as part of the same Business entitlement — meaning a single per-user line item covers more than just text drafting in Word and replies in Outlook.
• You accept that "Microsoft Copilot" spans multiple SKUs and that GitHub Copilot, Microsoft Security Copilot, Microsoft Copilot Studio, Copilot in Azure, and Copilot in Power Apps are sold separately and not covered by a Microsoft Copilot license.

Alternatives to consider

• Cursor — fits when you want an AI-first editor (a VS Code fork built around AI workflows, multi-file edits, and codebase chat) rather than an extension layered on a general editor. See Cursor vs GitHub Copilot.
• Replit AI — fits when the dev environment lives in the browser (education, hobbyist projects, quick prototypes) and you want AI inside that environment rather than inside a desktop IDE. See GitHub Copilot vs Replit AI.
• Claude — fits when your daily work is reasoning-heavy reading and writing across long documents and you want a careful general-purpose chat assistant for the analytical pieces. Useful complement to either of these two when the long-form drafting job is not really in-app at all. See Claude vs GitHub Copilot and Claude vs Microsoft Copilot.
• Gemini — fits when your team's canonical documents live in Google Workspace rather than Microsoft 365; Gemini is the analogous large-vendor AI that lives inside Gmail, Google Docs, Drive, and Search. See Gemini vs Microsoft Copilot.
• Notion AI — fits when your team's canonical documents already live in a Notion workspace and you want AI drafting / summarization / Q&A inside that workspace rather than as a separate writing helper or a Microsoft 365 add-on. See Notion AI vs GitHub Copilot and Notion AI vs Microsoft Copilot.
• Grammarly (AI) — fits when the job is in-place grammar, clarity, tone, and rewrite assistance across the apps a writer already types in (Gmail, Outlook, Google Docs, Word, Slack, Salesforce, LinkedIn, browser forms, mobile keyboards). See GitHub Copilot vs Grammarly (AI) and Grammarly (AI) vs Microsoft Copilot.
• Jasper — fits when the job is templated, brand-voiced marketing content at volume with team review, not in-editor code generation or in-suite productivity AI. See GitHub Copilot vs Jasper and Microsoft Copilot vs Jasper.

Bottom line

• Decide by which job you are hiring the tool for, not by which "Copilot" sounds more like the right brand. GitHub Copilot is an in-IDE coding assistant with chat, agent-mode features, and PR assistance around it. Microsoft Copilot, in its M365 Copilot Business SKU, is the AI surface inside Microsoft 365 (Word, Excel, Outlook, PowerPoint, Teams) and Windows. They do not overlap on either primary surface.
• If your job is shipping code in an IDE on GitHub every day, default to GitHub Copilot. Free at $0 (50 agent/chat requests and 2,000 completions per month, listed model set, Copilot CLI, no credit card required) is enough to evaluate; Pro at $10/user/month is the standard individual seat; Pro+ at $39/user/month adds broader model access and higher quotas; Business and Enterprise are Contact Sales for team and enterprise tiers.
• If your organization already runs on Microsoft 365 and Windows, default to Microsoft 365 Copilot Business at $18 / $18.90 / $25.20 per user/month depending on commitment, on top of a separate qualifying Microsoft 365 license. The distinctive value is AI inside Word, Excel, Outlook, PowerPoint, and Teams — plus admin tooling, Microsoft Graph search across work data (100+ connectors), Entra identity, AI-generated images / posters / banners / videos, and Copilot Notebooks. Consumer Microsoft Copilot Pro pricing and Enterprise / education SKU pricing should be verified directly on Microsoft's official surfaces.
• One license does not cover the other. Buying GitHub Copilot does not entitle you to Microsoft 365 Copilot Business, and vice versa. Mixed organizations with both kinds of work — developers in IDEs and knowledge workers in Microsoft 365 — will likely buy both, sized to the populations that use each surface (developer seats for GitHub Copilot, in-365 user population for Microsoft 365 Copilot Business).
• Re-verify both vendors' pricing/plans pages directly before any team-level commitment; both have changed SKUs, plans, quotas, and feature bundles multiple times, GitHub Copilot Business and Enterprise dollar amounts were not in scope of the 2026-05-22 plans-page fetch, and consumer Microsoft Copilot Pro USD pricing was not visible during the 2026-05-23 fetch.

• Microsoft 365 Copilot Business page: https://www.microsoft.com/en-us/microsoft-365/copilot/business — recorded as src-microsoft-365-copilot-business-2026-05-23 in data/sources.json with access_status = ok after a 2026-05-23 page-body read; this is the source of every Microsoft 365 Copilot Business plan, USD price, commitment-tier, qualifying-license requirement, and feature-bundle fact quoted on this page.

All four entries above resolve to official first-party URLs. Re-verify the two pricing/plans pages before any new pricing-sensitive quote. If a later refresh changes the access status of either src-github-copilot-needs-verify or src-microsoft-copilot-needs-verify, this page does not need to be rewritten — it never asserts a pricing or feature fact from either homepage source beyond what is visible on it today.

Update log

• 2026-05-24 (draft): first local draft created from templates/comparison-page-template.md. Both source tool pages (github-copilot, microsoft-copilot) are qa_passed per content/content-status.json.
• 2026-05-24 (QA): independent Section B walk-through completed. B1 source quality (both compared tool pages are qa_passed; all four cited sources exist in data/sources.json with access_status = ok; ≥ 4 sources total; no needs_verification or blocked source is treated as fact — passed; src-github-copilot-needs-verify and src-microsoft-copilot-needs-verify both carry a legacy "needs-verify" semantic in their ids but both currently have access_status = ok and are cited only as homepage URLs with no pricing/feature claim drawn from them; every GitHub Copilot plan/price/quota/editor claim is drawn from src-github-copilot-plans-2026-05-22; every Microsoft 365 Copilot Business plan/price/feature claim is drawn from src-microsoft-365-copilot-business-2026-05-23). B2 decision clarity (Quick recommendation names a distinct situation per tool; Bottom line provides 5 decision rules; GitHub Copilot pricing rows cite the 2026-05-22 source-read, Microsoft 365 Copilot Business pricing rows cite the 2026-05-23 source-read, GitHub Copilot Business / Enterprise USD figures and consumer Microsoft Copilot Pro USD pricing both routed to "verify on official site" — passed). B3 information density (≥ 900 words; use-case sections cover writing, coding/technical, research/fact-checking, and teams; comparison table separates source-backed fact rows from author-judgment rows via the Notes column — passed). B4 trust/safety/trademark/disclosure (no vendor disparagement; no false performance/accuracy/compliance guarantees; explicit "None of this is a benchmark claim" note in the coding/technical-work section; Trademark notice present and covers GitHub, Microsoft and its M365 stack, Anthropic, OpenAI, Notion, Jasper, Google/Gemini, Slack/Salesforce, LinkedIn, Cursor, Replit, and Grammarly; Disclosure block matches A5 — passed). B5 internal linking (15 internal links — passed). Disambiguation framing: the page is explicit that GitHub Copilot and Microsoft Copilot are not the same product despite the shared "Copilot" brand and shared Microsoft ownership — one license does not cover the other, the buyers are different (developer headcount vs in-365 employee population), the surfaces are different (IDE / GitHub web vs Microsoft 365 apps / Windows), and mixed organizations with both kinds of work commonly buy both sized to the populations that use each surface. content_status = qa_passed. Freshness: re-verify both vendors' pricing pages by 2026-08-20, which is 90 days from the older of the two pricing-page fetch dates (2026-05-22 for GitHub Copilot).
