Devin
Cognition's autonomous AI software engineer that works on coding tasks and opens pull requests for review.
What is Devin?
Devin is an AI software engineer from Cognition. You assign it a task, such as fixing a bug or building a small feature, and it works in its own sandboxed environment with a shell, editor and browser, then reports back and opens a pull request for your team to review.
Devin drew wide attention when it was announced in 2024 as one of the first agents marketed as an autonomous software engineer. Rather than suggesting lines of code, it takes on whole tasks end to end.
Teams typically interact with Devin through a web app, Slack or their issue tracker. Devin plans the work, writes code, runs tests and iterates, and you can watch its progress or step in to give guidance. When done, it opens a pull request.
Devin works best on well-scoped tasks: bug fixes, migrations, small features, writing tests and maintenance work. Cognition also acquired the Windsurf editor in 2025, adding an IDE product alongside Devin.
