You ask for something big, and leave it to it.
A whole checkout flow. You go and do something else while it works.
Visual proof for agent-built software
Every change your agent makes arrives with a screenshot or a screen recording attached. Point at what is wrong and say why. The note goes back with the coordinates on it — so the agent fixes what you pointed at, not what it guessed.

Features and benefits
Annotate
Drop a pin, drag a rectangle or throw an arrow at the thing that is wrong, and say why. Zoom to full resolution first if the problem is three pixels wide. Recordings take notes the same way: say “here, the sheet jumps” at 7.4 seconds and the moment is the comment.
Preview
Screens and walkthroughs are in the review at full resolution, the moment your agent finishes. No checking out the branch, no spinning up a preview environment, no waiting on a deploy to find out whether the thing even looks right.

}Handover
Threads come back as JSON with normalised 0–1 geometry against the revision you drew on, so your agent knows which pixels you meant — without you screenshotting anything, pulling the branch, or running it yourself to explain what is wrong.
Pull requests
Every upload returns an embeddable snippet. Drop it in the PR body and the images and recordings render where the review already happens — while the files live in object storage, so your git history stays code.
Sharing
Send a read-only URL to a teammate or a client and they are in — no account, no seat, no invite. It is a capability link, so it is never indexed, revocable in a click, and it never exposes the underlying file.
Pricing
You are charged for the evidence we store and serve, not for the people looking at it. A reviewer joins on a link with no account and no seat; an image is one evidence unit, a video counts by its length, and re-uploading the identical file counts for nothing.
For one person putting one project under the microscope.

Start free, upgrade laterWe are in early access, so accounts created before billing was switched on keep their existing limits. The price and every allowance are starting points we are still measuring against what this costs to run, and they will move before launch. If you hit one, tell us — we would rather move the number than break your loop.

Create a workspace, make an agent token, paste the prompt into whatever is writing your code. The next thing it builds arrives with its own evidence attached.
