AI code governance for PR review

AI wrote half this PR. Know the risk before you merge.

For eng managers and tech leads whose teams use Cursor or Copilot. One-click risk score, policy flags, and suggested tests on every AI-touched PR.

Who: Eng managers & tech leads shipping with Cursor/Copilot
Problem: You can't tell which lines an AI wrote — or how risky they are — until something breaks
Outcome: A clear risk score and review checklist on every AI-touched PR, before merge

Built for teams already on Cursor & Copilot

Why teams care

Risk score on every AI-touched PR
See how much of the diff was AI-assisted and which parts need a second look — without opening another editor.
Policy flags that match your team rules
Catch missing tests, secrets patterns, and “AI may not touch auth” rules as PR checks, not Slack reminders.
Suggested tests, not another backlog item
Get concrete test gaps tied to the AI-written hunks so reviewers know what to ask for before merge.

01
Connect your GitHub org
Install the Guardrail GitHub App on the repos where Cursor or Copilot already ships code.
02
Tag AI-touched PRs
We detect AI-assisted changes and attach a risk badge, policy flags, and suggested tests to the PR.
03
Merge with eyes open
Leads see the score in review. Risky diffs get the scrutiny they need — routine ones stay fast.

Is Guardrail another AI coding editor?+

No. We sit on the PR — risk scores, policies, and traceability for code your team already writes with Cursor or Copilot.

Do engineers have to change their workflow?+

No new editor. Reviewers get a check and summary on the PR; authors keep using the tools they already use.

When does the MVP ship?+

We're validating with design partners first. Join the waitlist and we'll invite early teams as the GitHub App / PR check opens.
