The tour
A fictional team, a real account
Kettleby is a made-up booking app for small fitness studios. Nina runs product there, and this is her Cobalt Capture account the week before a checkout launch. The app she is reviewing is invented; every Cobalt screen below is the real product, photographed by a script.
Everything she has flagged, in one place
Five reviews from the last week: a checkout pass before launch, a one-screenshot mobile bug, notes on onboarding copy, first reactions to a pricing page and a schedule clean-up. Each one is a link she has already sent to someone.
Capture the screen you are looking at
She picks the Kettleby window once, and each click of Capture takes the current frame and adds it to the review. Nothing to install. If the screenshot already exists, she pastes it, drops it in, or uses Add image instead, which is also how it works on a phone.
Point at the exact spot
Numbered pins go where the problem is, and each one starts a matching line in the note, so "2" in the text always means the second pin. Arrows, boxes, circles and short labels are there too, in a few loud colors.
Say it instead of typing it
Dictate turns what she says into text as she talks, then she tidies it up. In Chrome and Edge it runs in the browser; in other browsers she types.
Put the important thing first
Items move up and down, and a Summary can sit at the top so the reader gets the verdict before the evidence. Here the schedule note is about to move above the receipt.
What everyone else sees
The review is a page at a link. Anyone with it can read it and reply on a screenshot, no account needed. Her engineer confirmed the rounding bug right there.
On a phone the review reads top to bottom, pins and all. Plenty of people open a shared link from a chat on their phone, so it has to.
She can see how far it travelled, too: how many people opened it, when, and roughly where. It never stores a name or an IP address.
Hand it to your coding agent
The same review is a markdown document a coding agent can read directly: the summary, every note, and a link to each screenshot with the pins burned in. Copy it into Claude Code or Cursor, or let the agent fetch the link itself.
For an agent that should keep working on the review, adding screenshots or retaking one, she generates a token and pastes it over. It works on this review only, and generating a new one cancels the old.
Now yours
Quick shot is the fastest way in: one screen, one pin, one note, and a link you can paste anywhere. The full editor is one click from there. Or read a finished review we ran on a real product, the Shopify pricing teardown, built with the same tool.
