Callers still pass req.id — but the function now reads token.userId. Check api.ts:48.

Your AI CLI already costs $20/mo.
Why pay another $30/mo for someone else's PR reviewer?

GhRev wires your CLI directly into GitHub. Same brain, native workflow, one-time cost.

Three workflows, one extension

Everything you need on every PR

Senior-engineer review

Two-phase scout + investigate workflow. Posts inline comments as a pending review — you submit them. Confidence score on every comment, severity filtering, auto de-dupe.

  • ✓Reads file context, not just the diff
  • ✓Cites file:line for cross-file claims
  • ✓Never auto-submits

Workflow diagrams

One click renders a before/after flowchart in plain English. Zoom, pan, post as a PR comment. Reviewers understand the change in seconds.

  • ✓Mermaid output, native GitHub render
  • ✓Shared flow + diverging branches
  • ✓Cached per commit SHA

PR-aware chat

Ask anything about the PR. @-mention changed files. Select code on the page → "Ask GhRev" pops up. Replies link directly to the head SHA blob.

  • ✓Full Markdown rendering
  • ✓File paths auto-link to GitHub
  • ✓Persistent session per PR
Token analytics dashboard
Charts of tokens spent per day, per kind, per PR. All stored locally.
Per-comment confidence
Every comment ships with a self-rated confidence percentage.
Two-phase review
Scout pass identifies what to check; investigate pass writes the comments.
Heartbeat streaming
Long jobs don't time out; live progress chip on the PR page.

Privacy by architecture

Your code stays on your machine.

GhRev runs as a local server bound to 127.0.0.1. It invokes your local AI CLI, which talks to its own backend — never ours. We have no servers in the loop. We can't see your code, your reviews, your tokens, or your activity.

  • Loopback-only server
    Server binds to 127.0.0.1 — never reachable from the internet.
  • Pending reviews only
    Comments post as a pending review. You submit manually in GitHub UI.
  • No code uploads
    Diffs and file reads happen via your local checkout. GhRev never proxies.
  • Token redaction
    Streamed logs filter out anything that looks like a token before showing in the UI.
  • Source-available
    Buyers see the full source. Audit it. Modify it. Own it.

Why I built GhRev

At work, AI code writing tools increased our productivity by 100x. But PR reviews were still slow.

I used Copilot's review bot and Codex, but both were not enough. They just post comments at you. I wanted a copilot who could read the PR with me, answer my quick questions, and catch the edge cases I might miss. And I wanted all of this without leaving the PR page.

I was also already paying for an AI CLI, and I didn't want another subscription on top, or to burn API tokens.

So I built it for me. Started as a PR reviewer on autopilot, but then pivoted to a copilot with chat support and before/after workflow diagrams of the PR. I use it regularly on all my PR reviews now, and it is quite useful.

It has already caught some really good logical bugs in the code that manual review missed.

FAQ

Questions, answered

Does my code ever leave my machine?
No. GhRev runs a server on 127.0.0.1 that shells out to your local AI CLI. The CLI talks to its own AI provider. GhRev has no servers — we can't see your code or your reviews.
What if I don't already have an AI CLI?
The setup script walks you through installing one via npm. You'll need to log into it once with your own account; whichever subscription or API plan you have is the brain GhRev uses.
Does it auto-post comments to my team's PRs?
No. Every review is posted as a pending review — invisible to your team until you click Submit review in the GitHub UI. The server has no code path that submits.
What about private repos?
Works the same. GhRev uses your existing gh auth, so any repo you can access on GitHub, you can review with GhRev.
Lifetime means what, exactly?
You pay once, get added to the private GitHub repo, and pull updates forever. We commit to shipping updates for at least 24 months from your purchase. Refund within 30 days, no questions.
Why not just call my AI CLI directly?
You can. GhRev adds: the Chrome UI on every PR, structured review with confidence scores, inline GitHub posting via gh api, the workflow diagrams, chat with @-mentions, and token analytics. Saves the 30 minutes you'd spend wiring all of that yourself.
Windows?
Use WSL. Native Windows is not supported today.
What's the license?
Source-available. You can use it on any number of your own machines or inside your company. You can modify it. You can't redistribute it or resell it. (Polyform Strict-style.)
