Devin
by Cognition
PaidThe first AI software engineer — an autonomous coding agent that can plan, write, debug, and deploy code across complex engineering tasks.
Overview
Devin is the first autonomous AI software engineer by Cognition. Unlike code assistants that suggest completions, Devin autonomously plans, writes, debugs, and deploys code for complex engineering tasks. It integrates with GitHub and Slack, working on assigned issues independently and submitting pull requests for review.
