Sweep is an AI developer agent that automatically fixes GitHub issues by reading the issue description, understanding the relevant codebase, writing the fix, and opening a pull request — all triggered by simply labeling an issue with "sweep." Unlike copilots that assist while you code, Sweep operates independently on well-defined tasks, learning your codebase conventions and adapting to your team's feedback on its PRs over time. Sweep handles bug fixes, documentation updates, refactoring, and test writing, freeing developers to focus on creative and architectural work.
