Plannotator, open source runs locally, has code review: https://github.com/backnotprop/plannotator

and a code tour feature about to ship: https://x.com/backnotprop/status/2043759492744270027/video/1

- integrated comment feedback for agents

- inline chat

- integrated AI review (uses codex and claude code defaults)

Stage (op product) navigation tour is nice UX, about a day worth of work in addition to the incoming code tour.

this is for AI agent work though. That's cool, but not every team that wants better UX for complex work uses agents. Even if it "just works" for real scenarios, the marketing could be better.
