GitHub Copilot

GitHub Copilot was the first AI coding assistant to reach mainstream adoption, and its influence on everything that came after — Cursor, Windsurf, Codeium — is hard to overstate. When it launched in 2021, the idea of AI generating whole functions from a comment felt like a party trick. Now it’s a baseline expectation. Copilot normalized the category.

In 2025, it remains the most widely used AI coding assistant. That’s partly momentum, partly distribution (Microsoft owns both GitHub and VS Code), and partly because it’s genuinely good at what it does. The free tier, which arrived in late 2024, brought in a new wave of users.

What Copilot does

The core experience is inline autocomplete: as you type, Copilot suggests the next line, the next function, or an entire block of code based on context from the surrounding file. Accept a suggestion with Tab, reject it by continuing to type. Over time it gets better at predicting your patterns.

Copilot Chat adds a sidebar where you can ask questions, request explanations, generate tests, or describe features you want to implement. It has access to your open files and can understand your project at a basic level. For developers who don’t want to leave their editor, this integration is convenient.

The GitHub integration matters

Where Copilot has a real edge over standalone AI editors: its integration with GitHub itself. You can use Copilot in pull request reviews, in GitHub.com’s interface, in GitHub Actions workflows. For teams already on GitHub, this creates a coherent AI-assisted workflow that doesn’t require adopting a new tool.

The honest comparison to Cursor

Copilot’s autocomplete is good. Cursor’s is better. This is almost universally agreed upon by developers who’ve used both. The gap narrows over time as Microsoft iterates, but if autocomplete quality is your primary criterion, Cursor currently wins.

Where Copilot competes is on price ($10/mo vs. $20/mo for the full Cursor Pro experience), ecosystem integration, and the simple fact that many developers already use it and have no reason to switch.

For non-technical users

This is the most honest thing to say about Copilot: it is not a tool for non-technical founders. It doesn’t generate apps, it doesn’t explain what software is, and it doesn’t hide the complexity of code from you. It makes developers faster. It does not make non-coders into developers.

If you don’t know what a function signature is, or how to run a local development server, Copilot will not help you build anything. The rating of 2 reflects the small minority of non-coders who have enough coding literacy to benefit — not that it’s a bad tool, but that it’s the wrong tool for this audience.

Bottom line

Copilot is a solid, dependable AI coding assistant for developers. The $10/mo price is the most affordable entry point in the category. If you’re a developer already living in VS Code who wants AI assistance without switching editors or workflows, it’s a reasonable choice. If you’re a non-technical founder hoping to build without coding, look elsewhere.
