For anyone reviewing a pull request
Get a video in every pull request. Every change, walked in a real browser.
Kosuke covers the cases the change touches and attaches the recording to the pull request. Review what the change does, not what the description claims it does.
- Guest reaches checkout and pays
- Declined card shows the retry state
- Signed in user keeps the saved address
- Receipt email leaves the worker
Read from the diff. How the cases get written
Cases read from the diff
The change already says which routes, components and permissions it touches. That is the test surface, derived per pull request instead of maintained by hand in a spec file.
Run in a real browser
Real clicks, real network, real auth, real database. Not a headless approximation of your stack and not a unit test standing in for a user.
Readable by anyone
A designer or a founder can watch a video and say whether the change is right. Nobody outside the team reads your Playwright specs.
It runs where the change lives. No new tool to open
The cases live next to the change
Kosuke reads the diff and writes the cases it implies, each one ranked by how much it would hurt to get wrong. They sit in the session next to the chat, so you can drop the ones that do not matter before the run starts.

The recording lands on the pull request
The run happens in the sandbox that already has your app on its branch, and the video is attached to the pull request when it opens. Reviewers press play instead of reading a description of what changed.
