What is Devin?

Devin, from Cognition, is an autonomous AI software engineer rather than an autocomplete tool: you hand it a task — a bug fix, a feature, a migration — and it plans, writes code, runs tests, and browses documentation in its own sandboxed workspace, reporting back with a finished pull request for your team to review and merge.

It connects to GitHub, Slack, and Linear, so tasks can be assigned in chat and progress followed like a remote colleague's. Devin works best on well-scoped, repeatable engineering work and refactors; pricing is usage-based on top of a subscription, so costs depend on how much compute your tasks consume, and results still need senior review.
