Code Review Enviornment for the Modern Era

A local diff viewer for reviewing agent-written code — git, jj, Perforce, and GitHub/GitLab PRs. Annotate lines and files; your notes feed straight back into your agent session. Optional AI layer: inline Q&A, guided reviews, and launchable review agents. Free, MIT / Apache-2.0, runs on your machine. Plannotator opens a local diff viewer (git, jj, p4).
