AI code review for any diff — paste it, get issues ranked by severity.
No GitHub App. No repo permissions. No login for your first review of the day. Paste a git diff or a public PR link and get bugs, security holes and logic errors, worst first, with concrete fixes.
Quick answer: DiffReview reviews pasted diffs and public GitHub PRs with AI, ranked critical → high → medium → low. 1 free review per day, then $9 for 20 reviews or $29 for 100 (points never expire). Your code is deleted after review — never stored, never trained on, never seen by a human.
Max 30,000 characters / 1,000 lines. Your diff is sent to the AI once for review, then deleted — it is never stored or logged.
How it works
1. Paste. Drop in a git diff, or a public GitHub PR link. 2. Review. The AI reads the change and ranks every real issue by severity — critical, high, medium, low — with the file, the line, and exactly what to change. 3. Ship (after a human looks). The review is advice, not a guarantee: always have a human review before shipping.

FAQ
What is DiffReview?
An AI code review tool for developers. Paste a git diff or a public GitHub pull request link and get a review ranked by severity — critical, high, medium and low — plus concrete fix suggestions. It needs no GitHub App, no repo permissions and no GitHub login.
Is DiffReview free?
Yes — one full AI code review per day is free, no account needed. After that, one-time point packs cost $9 for 20 reviews or $29 for 100 reviews. Points never expire.
What happens to my code after review?
Your diff is deleted after review. It is never stored, never logged, never used for training, and never viewed by a human. Only counts and sizes are recorded (how many reviews ran, how big the diff was). See the privacy policy.
Can DiffReview review private repositories?
No — and that is by design. DiffReview only reviews diffs you paste yourself and public GitHub pull requests. It never logs into GitHub and never pulls private code.
Does the review guarantee my code is bug-free?
No. The review is advice, not a guarantee — it can miss issues and it can flag things that are fine. Have a human review before shipping.
What size diffs can I review?
Up to 30,000 characters / 1,000 lines per review. For larger changes, split the diff and review it in parts.
