Where humans and agents meet.

Code review for the agentic era. A calm inbox, a fast diff, and reviews that go straight back to GitHub.

When agents write the code, review is the job.

Pull requests now arrive faster than any team can read them. diffbox is code review rebuilt for that pace: a calm inbox that surfaces what needs you, and a diff fast enough to keep up.

Look closer.

Read every change the way people study her: unhurried, in full detail. Comments sit right on the line, context is a keystroke away, and your verdict lands straight back on GitHub.

Agents read every line. You make the call.

Let agents take the first pass on every pull request. The judgment stays with you, with the full context in front of you when you make it.
