HeyDeer AI

HeyDeer is a high-precision AI code review agent that reviews every pull request on GitHub, catches real problems before they ship, and can fix them for you. When your coding agents or teammates write code, HeyDeer reviews it as an independent second reviewer.

Open a pull request and HeyDeer reviews it. Click Autopilot and it fixes findings, failing checks and merge conflicts, pushing to the branch round after round until the PR is ready to merge. Every review includes a walkthrough that groups the change and shows what needs an engineer's attention, and you can mention @heydeer on a PR or issue to ask questions or hand off tasks.

HeyDeer keeps false positives down by having a different model verify each potential issue against the code before posting it. It reports 99.0% precision on ReviewBench, GitHub's open benchmark for AI code review, and found 78% more issues than GitHub Copilot on the same pull requests. It follows your team's REVIEW.md, AGENTS.md and repository checks, and every comment cites the line behind it.
