GReview
AI Code Governance
Claude, Codex, and Cursor can review a diff. GReview reads every PR against what the ticket asked for, your architecture and guardrails in GKS, your whole codebase, and every other open PR, then posts one prioritized review in minutes. The hand that writes the code is never the hand that checks it.

print(). Revoke and rotate immediately.send_alert()channel param not reflected in its caller in billing.py, guaranteeing a TypeError at runtime.process_bulk_billingIN clause → 1,000× speedup.Every PR is checked against the ticket's business requirement, not only whether the code is clean. No coding agent does this by default; GReview gets the intent from Jira through GKS.
Through GKSFlags every other open PR touching the same functions, a conflict class point tools structurally can't see.
Unique to GarthWhole codebase, architecture rules, team guardrails, and scale and compliance guidelines, all served from GKS. One prioritized review, critical to low. The 4.2% false positive rate is context, not luck.
The brain mattersThe agent that wrote the code never signs it off. GReview reads only what the job needs through GKS and writes back only through your keys. Cloud, VPC, or on-prem.
Independent by designNot a wall of style nits. One assessment, findings ordered by what will actually hurt you in production, with the fix, the file, and the line.
GReview opens with a verdict, then groups findings by impact. A hardcoded secret and a breaking API change surface first. Duplicate formatting logic sits at the bottom, where it belongs. Your reviewers read top-down and stop when the risk runs out.
Hardcoded live secrets, SQL injection, unsafe input handling, caught before merge, not in an incident report.
New required parameters whose callers weren't updated: the runtime TypeError your tests would've found in prod.
N+1 patterns, edge cases, and duplicated logic, each with a concrete, apply-ready fix.

The goals are legitimate, but the implementation is critically flawed and should not be merged in its current state. It carries multiple severe security vulnerabilities plus breaking API changes that will cause runtime errors in production.
print statement, an immediate security-incident risk. Revoke and rotate the key, then move it to a secrets manager.process_bulk_billingsend_alert()channel parameter is not reflected in its existing caller in billing.py, guaranteeing a TypeError at runtime. Update all call sites and add a regression test.IN clause resolves it in a single round trip.A reviewer looks at one diff at a time. GReview knows every open PR that touches the same functions, before two of them merge and quietly break each other.
Clean code that builds the wrong thing still ships the wrong thing. GReview reads the ticket's business requirement through GKS and reconciles every PR against it: what was asked, what was built, and what rode along that nobody asked for.
payments/retry.py and covered by test_retry_backoff.process_refund was modified, but no ticket asked for it. Flagged for the reviewer, not blocked.Claude Code, Codex, or Cursor only know the ticket if someone wires up MCP and keeps a skill current. GReview gets the intent from Jira through GKS on every review, with nothing for your developers to set up.
The agent that wrote the code is never the agent that signs it off. The check runs on your organisation's context, not the author's session, so it does not share the author's blind spots.
GRelease runs Ask vs Built across a whole release train from the same GKS context, so "did we build what we promised" has one answer at the PR and at the freeze.
GReview profiles the change, ranks the real hot paths, and hands back a fix with the numbers to justify it, the kind of insight a static reviewer never surfaces.
A defect that reaches production costs many times what it costs to catch in review. GReview reads the whole codebase on the first pass, against your guardrails, so far more is caught before it ships.
GReview speeds your reviewers up. It does not replace them.
GReview never touches your systems directly. It reads through GKS, the governed knowledge layer you control, and posts back only through your keys.
On a new PR, GReview requests the context it needs from GKS: your repository graph, architecture rules, guardrails, and the ticket behind the change.
GKS checks policy and guardrails at intake, releasing only what this job is authorized to see.
Scoped context: the diff, the relevant symbols, your coding standards, the ticket's intent, and open PRs, nothing beyond it.
A prioritized, actionable review lands on the PR, written back to your environment through your key.
Garth Universe is the control plane. Choose which repos GReview watches, author your own guardrails and architecture rules, decide when it runs, and route it through your own model keys.
garth-rr in a comment.Agents never touch your systems directly. Everything reads through GKS, the governed boundary you control, and every action writes back only through your keys. Your own coding agents can read the same context over MCP. Sign-in is Google or Microsoft SSO, with roles and audit logs in Garth Universe.
Explore GKS →GKS ingests only the sources you authorize. Nothing you have not connected ever enters.
Each agent gets the exact data required to do its work, filtered at intake, and nothing beyond it.
Agents read from GKS, never your host systems. Misuse stops at the boundary, not inside your stack.
When an agent writes back to a system, it goes through credentials you provision, scope, and revoke at will.
GKS runs in Garth Cloud. Your systems stream in over an encrypted, governed channel. Fastest to start, nothing to host.
Point tools each read one signal. GReview grounds review on the same shared brain as security, release, and ROI, so it sees what none of them can.

The wedge is competitive. The platform is not.
Reclaimed review time, faster merges, and fewer escaped defects. Move the sliders to your team and see the return.
Illustrative model. Assumes GReview handles ~85% of first-pass review work and cuts PR wait time ~95%, with a bounded per-PR context-switch cost. PR-review impact only. Real value is typically higher across the wider workflow.
GReview bills on active developers, a contributor active in the trailing 30 days. Dormant seats are never charged.
Building with the first cohort? Design-partner rates from $10–$12 / dev, plus a 6-week all-features trial with your own key. Bring your own model key and the price drops about a third.
Every plan includes GKS (the knowledge backbone), GAssist, and G-IDE.
In Slack & TeamsGAssist puts GReview in Slack and Teams. Review results, guardrail flags, and inter-PR collisions land in your channel, and you approve, request changes, or merge right there, without a tab switch.
