PR Review Presence Radar

See who is reviewing the same pull request, live

Problem

As teams grow, dozens of PRs pile up on one reviewer each day; review, merge, and deploy all bottleneck on a single person. Developers already let a Codex bot do a first pass, but still hit the case where they ping someone for a review and hear 'I'm already on it,' while multi-model review costs and disagreement arbitration remain unsolved.

Solution

A lightweight PR review-presence tool: a browser extension or GitHub App shows who is currently viewing or reviewing a PR, supports one-click claim with timeout release, and aggregates multi-model AI review comments by file and line so humans only resolve conflicts.

Users

Engineering teams of 10–50 with high PR volume; tech leads maintaining multiple repos; teams running several AI review bots.

MVP

Browser extension plus minimal backend to show live reviewers on a PR page; 'reviewing' status with timeout release; GitHub Action to aggregate multi-model comments by file and line; read-only with no auto-merge; free for public repos, paid per seat for private repos.

Revenue

Per-seat SaaS subscription, $3–5 per user per month for private repos; enterprise self-hosted with SSO.

Why now

AI coding has shifted the bottleneck from writing code to reviewing it, and multi-model review creates cost and arbitration pain that small tools can address without competing with GitHub itself.
