Verithink inside Claude

You can ask Claude to check a text with Verithink without leaving the chat. The scores and the findings come back into the conversation, the evaluation is saved to your Verithink library, and it costs the same jobs as in the app. Verithink is a connector: Claude calls it, and the evaluation itself runs within Microsoft Azure, as always.

Start free

Before you start

A Verithink account (free, at app.verithink.ai) and a Claude account. Custom connectors can be added on every Claude plan; the Free plan allows one.

Connect, once

On claude.ai; the desktop and mobile apps pick it up from there.

  1. In Claude, open Customize, then Connectors.
  2. Choose Add custom connector, paste this address, and add it: https://api.verithink.ai/mcp
  3. Click Connect. A Verithink window opens: sign in if you are not signed in already, then read what Claude will be able to do (run evaluations, which use your jobs; read your library; see your plan and the jobs you have left) and click Allow.
  4. Claude shows Connected. Connectors belong to your Claude account, so the desktop and mobile apps have it from then on.

In a chat

  1. Turn Verithink on for the chat: the + menu, then Connectors.
  2. Paste the text and ask: "Evaluate this with Verithink." Claude may ask you to approve the call the first time. Claude then gives the scores and the findings in its own words and points at the strongest and the weakest points.
  3. Ask "How do I strengthen it?" and Claude brings back the Improve list, one item per finding.
  4. "Show my recent Verithink evaluations" and "How many jobs do I have left?" work too.

In Claude Code (the terminal)

claude mcp add --transport http verithink https://api.verithink.ai/mcp

then /mcp to sign in. The same consent page; the same account.

Good to know

  • PDFs and screenshots: drop them into the chat as you normally would. Claude reads them and sends the text to Verithink.
  • Jobs: an evaluation from Claude costs what it costs in the app, and the Plans page in the app shows what is left.
  • Disconnect: in the app, Account, Connected apps, Disconnect. Removing the connector in Claude as well is tidy, but it is the app that makes the connection dead.
  • The first evaluation after a quiet spell can take up to a minute, while a worker starts; the next ones come back sooner.
  • Other assistants: Claude only, for now.
