Cobalt Capture

Cobalt Capture turns product feedback into something an AI agent can act on: annotated screenshots and notes in a review anyone can open by link.

Connect with your Cobalt account and Claude can:

Read. Give Claude any Cobalt review link and get_review returns the reviewer's notes as text plus each annotated screenshot as an image, so it sees exactly what was marked and what to change.

Write. Turn a QA pass, a browser test, or a product study into one review saved to your account: create_review to start, add_screenshot and add_note as it goes, replace_screenshot to retake a capture, and update_review to put the verdict at the top. No browser needed for public pages: add_screenshot can render any public URL at desktop or mobile size.

Find. list_my_reviews finds your reviews by name, and search and fetch look up the product teardowns Cobalt has published.

Built-in study playbooks (pricing teardowns, positioning, comparisons, usability and flow passes) give Claude a written method you can pick as a prompt, and the full text of each is published at cobaltcapture.com/developers#playbooks. Each one states its plan first, and the ones that use a product wait for your go. Temporary test inboxes let Claude test the signup flow of a product you own or are authorised to test: each lasts 24 hours, only receives mail, and up to 20 can be created per hour.

For product managers, designers, founders and developers who want feedback and QA runs captured as reviews a person or an AI can read.
