• get_review

  Fetch a Cobalt Capture review by its share link or slug. Returns the reviewer's notes as text AND each annotated screenshot as an image, so you can see exactly what was marked and what to change.

• create_review

  Start a new Cobalt Capture review and get a handle for filling it in. Use this to compile the findings of any site study — a usability pass, a pricing teardown, a positioning audit, a QA run — into one shareable, durable report with real screenshots. Works from any client, chat…

• add_screenshot

  Append one screenshot, with an optional title and note, to the end of a review. The image is stored in Cobalt and shown in the review. Three ways to supply it: `page_url`, a public page that Cobalt renders in a headless browser (`viewport` 'desktop' at 1280px or 'mobile' at 390p…

• replace_screenshot

  Overwrite one existing screenshot in a review with a new capture, in the same position. Destructive: the old image and any pins or annotations on it are removed and cannot be recovered; the title and comment change only if new ones are passed. Works on screenshots only, not note…

• add_note

  Append a free-standing text note (not tied to a screenshot) to a review created by create_review. Use for context, steps taken, or a summary of findings between screenshots.

• update_review

  Set or replace a review's summary and/or title. The summary is shown at the top of the review, above every screenshot and note. Replaces any existing summary or title.

• get_playbook

  Return the full text of a Cobalt study playbook: a step-by-step method for a kind of product review that ends in a shareable Cobalt review. Available: 'pricing_teardown' (can a buyer tell what they would pay and which tier fits; public pages only); 'website_teardown' (what each…

• search

  Search the studies Cobalt Capture has published on well-known products: pricing teardowns, positioning audits, and head-to-head comparisons (for example Canva pricing, Spotify vs Apple Music). Returns matching studies as {id, title, url}; pass an id to fetch for the full text. I…

• fetch

  Fetch the full text of a Cobalt study by the id search returned, or of any Cobalt review by its URL (/r/<slug>) or slug. Returns text: findings, prices, the comparison matrix, and the underlying review's notes with links to its screenshots. Use get_review instead when you need t…

• create_inbox

  Create a temporary email inbox for testing the signup or email flow of a product the user owns or is authorised to test, within that product's terms. Returns an `address` to enter in the product's form and an `inbox_token` for reading it with check_inbox. Each inbox expires 24 h…

• check_inbox

  Read mail delivered to an inbox from create_inbox, newest first, for example a verification code or confirmation link from the signup email of the product being tested. Requires the inbox_token, so only whoever created the inbox can read it. Returns immediately; mail usually arr…

• email_review

  Email a link to a review to the person who ran the study. Sends only to an address that belongs to a verified Cobalt account (other addresses are refused, which keeps the tool from being used to send unsolicited mail). The email contains only the review link, never text supplied…
