Devin is an AI agent from Cognition that performs software engineering tasks autonomously alongside human developers. It learns a codebase's context and conventions, integrates with tools such as GitHub, Linear, Slack, and Datadog, and can run multiple agent instances in parallel on large, multi-repository projects.
Typical uses include large-scale code migrations and refactors, bug fixing, CI failure resolution, and PR creation and review, with humans kept in the loop for review and approval. It is offered across cloud, desktop, and CLI interfaces.
