About Ellipsis
AI code reviews & bug fixes
Ellipsis will help your team merge code 13% faster. Ellipsis is an AI developer tool that automatically reviews code and fixes bugs on pull requests. It uses LLM agents to catch logical errors, security issues, and can even enforce a team's style guide. The coolest part is that after Ellipsis identifies an issue, developers can tag @ellipsis-dev to have Ellipsis implement the fix. Internally, Ellipsis actually executes the code it generates, just like a human does. As a result, we allow developers to generate working, tested code directly from GitHub/GitLab.
