Microsoft Copilot and GitHub Copilot share a name, but they’re built for very different jobs. One is a general AI assistant baked into Windows and Microsoft 365. The other is a code tool used by over 1.8 million paying developers.

Copilot: where it shines, where it lags
Microsoft Copilot is Microsoft’s general AI assistant. It runs on GPT-4o and shows up in Windows 11, Microsoft Edge, Microsoft 365 apps, and at copilot.microsoft.com. The free version lets you chat, generate images using DALL-E 3, and pull answers from the web. Copilot Pro costs $20 per month and adds priority access during peak hours, faster image generation, and deeper ties to Word, Excel, and PowerPoint.
What Copilot does well: It’s genuinely useful for everyday office work. In Word, it drafts emails, summarizes long documents, and rewrites paragraphs in a different tone. In Excel, it writes formulas and builds charts from plain English instructions. In Edge, it summarizes any webpage in seconds. For someone who spends most of their workday inside Microsoft 365, the time savings add up fast. Microsoft reports that enterprise Copilot users complete tasks 29% faster on average.
The image generation is also strong. DALL-E 3 inside Copilot produces quality output, and the free tier is generous with it. You don’t need a separate Midjourney or Adobe Firefly subscription if your image needs are modest.
Where Copilot falls short: It’s not a coding tool. It can write a basic Python snippet on request, but it won’t autocomplete your code as you type, suggest the next line in your editor, or catch bugs in a pull request. Developers who want AI help inside their IDE will find Copilot too shallow to rely on for real work.
It also has consistency problems with facts. Copilot pulls from the web in real time, which helps with recent events, but it sometimes delivers confident-sounding answers that turn out to be wrong. Verify anything that matters before you act on it.
The $20 Pro tier is priced identically to ChatGPT Plus. But if you don’t already subscribe to Microsoft 365, many of Copilot Pro’s strongest features are locked out. The free tier is useful on its own, but its ceiling depends almost entirely on which Microsoft products you already own.
For people who aren’t developers and who live inside Microsoft’s apps, Copilot is the right call. It’s not trying to replace your terminal. It’s trying to make your inbox, your spreadsheets, and your browser faster every day.
GitHub Copilot: where it shines, where it lags
GitHub Copilot is an AI coding assistant built specifically for developers. It launched in 2022 as the first AI coding tool to reach mainstream adoption and now counts over 1.8 million paying subscribers. It works inside Visual Studio Code, JetBrains IDEs, Neovim, and the GitHub web interface directly.
The tool works two main ways. First, it autocompletes code as you type, offering entire functions, test cases, and docstrings inline without leaving your editor. Second, it runs a chat interface inside your IDE where you can ask questions about your code, request refactors, or get help with a specific error message. GitHub Copilot also writes pull request descriptions and flags security issues in the GitHub interface.
Pricing has four tiers. The free plan includes 2,000 code completions and 50 chat messages per month. Individual paid plans start at $10 per month. Business plans cost $19 per user per month and add policy controls, audit logs, and IP indemnity. Enterprise costs $39 per user per month and includes access to your company’s internal codebase through GitHub Enterprise.
What GitHub Copilot does well: The code completions are fast and contextually aware. It reads the files you have open and suggests code that fits your existing patterns, not just generic boilerplate. Developers consistently rank it among the top productivity tools for writing repetitive logic, generating unit tests, and filling out standard functions. A 2023 GitHub study found that developers using Copilot finished coding tasks 55% faster than those without it.
The chat feature has improved substantially since launch. You can highlight a buggy function, type “fix this,” and get a working replacement with a plain-language explanation. It supports over 30 programming languages, with the strongest performance in Python, JavaScript, TypeScript, Ruby, and Go.
Where GitHub Copilot falls short: It won’t help you write a marketing email or summarize a contract. It’s purely a developer tool. Its chat answers occasionally recommend deprecated libraries or patterns that don’t match modern best practices, so you still need to review every suggestion, especially anything touching authentication or security.
The free tier is also tight. 2,000 completions sounds like plenty until you’ve been coding for a few hours straight. Most active developers will need the $10 plan within a week of real use.
For teams that care about IP protection, the Business and Enterprise tiers provide safeguards the free and Individual tiers skip entirely. That matters for any company shipping proprietary code.
The verdict
Pick Microsoft Copilot if you’re not a developer. If your workday runs inside Word, Excel, Outlook, and Edge, Copilot saves time on every document you touch. The free tier is genuinely useful, and the $20 Pro tier earns its cost if you’re already paying for Microsoft 365. Non-technical users get the clearest return here.
Pick GitHub Copilot if you write code for a living. The autocomplete alone justifies $10 per month for most working developers. The 55% speed gain on coding tasks isn’t a marketing claim; it lines up with what independent developers report in public surveys. Teams handling proprietary code should look hard at the $19 Business tier for the audit and compliance features.
The names overlap on purpose. Microsoft owns GitHub, and both products carry the Copilot brand. But they serve separate audiences and do almost nothing useful for each other’s users. A developer paying for GitHub Copilot doesn’t need Microsoft Copilot. A business analyst paying for Copilot Pro doesn’t need GitHub Copilot. Buy the one that matches your actual job title.
FAQ
Is Microsoft Copilot the same product as GitHub Copilot?
No. Microsoft Copilot is a general AI assistant for writing, research, and productivity tasks inside Windows and Microsoft 365. GitHub Copilot is a coding assistant built for developers working inside an IDE. They share the Copilot name because Microsoft owns GitHub, but they carry separate subscriptions, separate feature sets, and separate target users.
Can GitHub Copilot replace a full code review?
Not yet. GitHub Copilot spots syntax errors, suggests refactors, and flags common security patterns, but it misses logic bugs, architecture problems, and context that only a human reviewer catches. Use it to speed up the mechanical parts of a review. Don’t use it as a substitute for a second set of human eyes on anything touching production or security.
Which costs less, Microsoft Copilot or GitHub Copilot?
Both start free. Microsoft Copilot’s paid tier is $20 per month. GitHub Copilot’s paid individual tier is $10 per month, making it cheaper head to head. Copilot Pro makes more financial sense if you already subscribe to Microsoft 365, since the productivity features inside Word and Excel justify the higher price for non-developer users.
