The approval gap
LGTM stopped meaning anything.
Agents write PRs faster than anyone can read them. Reviewers skim, trust the tests, and click approve. The checkmark says someone reviewed the change, but often nobody really did. That’s worse than no review, because it looks like oversight.
AI reads every changed line
Diffwitness reviews the changed code and relevant repository context for risks and side effects, so nobody has to pretend they read the whole diff.
A real sign-off on behavior
Your approver sees what changes for users in plain English and checks it against what you intended. Engineers, founders, or PMs can approve, because they’re judging behavior, not syntax.
Accountable to the commit
Each approval records who signed off, on which commit, with a link to the Slack discussion. New code needs a fresh review.
How it works
AI reads the code. A named person approves what it does.
Drop in the PR
Post a PR link in a channel with Diffwitness. No special prompt or write-up required.
Check the AI review and functionality
Diffwitness reviews the code with AI and posts its findings in Slack. Check what changes for users, what needs attention, and the GitHub check status.
Reply LGTM
Your chosen approver replies @Diffwitness LGTM, even if they don’t write code. The GitHub App records approval for that commit, with a link back to the discussion.

We already use an AI code reviewer. Why this?
Most AI review tools leave comments in place of a human reviewer. Diffwitness keeps a person accountable: a named teammate signs off on what the change does, and that approval is tied to the exact commit. It works alongside the tools you already use and reads their GitHub check status.
Isn’t approving behavior instead of code riskier?
Compared with a careful line-by-line review, it’s a different check. Compared with what most teams actually do with large AI-written PRs, skimming and clicking approve, it’s a real one. Diffwitness’s AI still reviews the changed code and flags risks, and your GitHub branch protections still apply.
Who can approve a PR?
You choose the people who can approve. They can be engineers or nontechnical teammates, such as founders, PMs, and designers. Your admin pairs their Slack and GitHub accounts during setup. Authors cannot approve their own PRs. Approval belongs to the reviewed commit; new code needs a fresh review.
What access does it need?
You choose the repositories, Slack channels, and people who can approve. We’ll configure those boundaries with you during onboarding. Read about access and approval controls.
What will it cost?
Start with a 14-day no-card trial. Afterward, pricing is $29 per developer per month, including 100 pooled review credits. Approvers are free, and there are no automatic overages. See pricing details.
What happens after I start a trial?
Create a workspace to start a 14-day trial with 10 shared review credits and up to 3 developer seats. No card is required, and the trial does not renew automatically.
Make your next approval mean something.
