🙌 2For teams shipping with AI
Your team is rubber-stamping AI code.
Nobody reads every line of an AI-written PR anymore, so “Approved” has quietly stopped meaning anything. Diffwitness reads the code, explains what it actually does in Slack, and gets a real sign-off on the behavior, tied to the exact commit.
14-day trial · 10 shared review credits · no card required.
Approve what the code does, not just the diff.

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 reviews the changed code
Diffwitness’s AI reads the diff and the code around it, then explains the change and its risks in Slack. Give your reviewer something to judge without pretending they read the whole diff.
A real sign-off on behavior
Your teammate checks what the change does against what you meant to build. They ask questions in the thread before putting their name on the decision.
A decision you can trace
The approval names the person who made the call and links to the Slack discussion. You can look back at the reasoning after the PR is merged.
How it works
AI reads the code. A named person approves what it does.
01
Drop in the PR
Post a PR link in a channel with Diffwitness. No special prompt or write-up required.
02
Check what the change does
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.

Start small
Try it on the next PR you’d have skimmed.
Connect GitHub and Slack, choose who can approve, and run your next big AI-written PR through it. See whether your approvals start meaning something again.
We already use an AI code reviewer. Why this?
Most AI review tools leave comments in place of a human reviewer. Diffwitness keeps a named teammate accountable for what the change does. Their approval is tied to the commit they reviewed. 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?
Choose who can approve during setup. They can be engineers or teammates who know the intended behavior, such as founders, PMs, and designers. 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 and connect GitHub and Slack. Your 14-day trial starts with your first review and includes 10 shared review credits and up to 3 developer seats. No card is required, and the trial does not renew automatically.
