Cognition
Cognition's autonomous AI software engineer — plans, codes, debugs end-to-end
Devin is Cognition's AI software engineer that autonomously handles full engineering tasks: reading requirements, planning an approach, writing code, running tests, fixing bugs, and opening pull requests — without human intervention in the loop. In June 2026, Cognition rebranded Windsurf as Devin Desktop, an agent-neutral IDE with the open Agent Client Protocol (ACP) for multi-agent orchestration. Backed at a $25B valuation after a $1B raise in May 2026. **Step-by-step:** 1) Open devin.ai or install Devin Desktop. 2) Assign a GitHub issue or natural-language task. 3) Devin creates a plan, opens a browser/terminal, writes code, and runs tests. 4) Review the PR it opens. **Best for:** engineering teams automating routine tasks, refactoring legacy codebases, unblocking solo founders on backend work.
First AI software engineer raised at $25B — autonomously opens PRs and fixes bugs end-to-end.
