Use ClaimBob in Claude

  2. Choose Add custom connector. Name it ClaimBob, and enter the URL below. Leave the advanced settings empty.
  3. Choose Connect, and sign in to your ClaimBob account.

Good to know

  • Checks from Claude use the checks on your ClaimBob account, as on the website. Before each check, ClaimBob says what it costs.
  • ClaimBob reads images and videos from public https links. For an image attached in the chat, or a file only on your device, ClaimBob gives you one upload link: upload the files there, go back to the chat, and the check and its result follow there.
  • An ad ClaimBob does not cover (a cosmetic, CBD, alcohol) is refused before a check is used.
  • To disconnect Claude, remove it under Connected apps in Team and settings. How we handle data from connected apps is in our privacy notice.

ClaimBob is an automated pre-check of advertising claims against the GB register, the CAP Code and platform policies. It is not legal advice.
