Devin is Cognition's autonomous AI software engineer: an agent that engineering teams delegate tasks to, such as large-scale code migrations, refactors, bug fixes, and pull-request review. It is offered in several forms — Devin Cloud, a desktop app, a CLI, Devin Review, and a Windows VM — alongside enterprise and government solutions.
The site's featured case study describes Nubank delegating the migration of a multi-million-line ETL monolith into sub-modules to Devin, reporting an 8–12x engineering-time efficiency gain and over 20x cost savings compared with distributing the refactor across its engineers.
