What is Devin?

Devin is an AI software engineer designed to work autonomously on coding tasks. Rather than assisting with individual commands, it can plan and execute complete development projects, from writing code to debugging and deploying applications. The tool is intended for teams and developers who want to automate routine coding work and accelerate project delivery. Devin can read codebases, write new features, fix bugs, and handle deployment processes with minimal human intervention. It's notable for attempting to function as a full developer rather than a code completion or suggestion tool.
