Connect Claude, ChatGPT or another AI app to your books

2. What you need

• An account on the AI app, for example Claude or ChatGPT.
• This address, which the app asks for: https://write.journzy.com/mcp

3. Connect from Claude

1. In Claude, open the settings, go to “Connectors” and choose “Add custom connector”.
2. Paste https://write.journzy.com/mcp as the address.
3. Claude opens Journzy. Sign in if Journzy asks you to.
4. On the Journzy page, read what the app asks for. Then tick the projects that it may read. Nothing is open until you tick it.
5. Click “Allow”.

You go back to Claude, and you can ask it about your books. Journzy sends you an email each time a new app connects to your account.

Claude Code: in a terminal, run claude mcp add --transport http journzy https://write.journzy.com/mcp. Then type /mcp in Claude Code to sign in. Because Claude Code runs on your computer, the Journzy page shows the local address that receives the answer. Approve only if you started the connection on this computer just now.

4. Connect from ChatGPT

1. In ChatGPT, open the settings and add a new app. ChatGPT calls connectors “Apps”.
2. Paste https://write.journzy.com/mcp as the address.
3. ChatGPT opens Journzy. Sign in if Journzy asks you to.
4. On the Journzy page, read what the app asks for. Then tick the projects that it may read. Nothing is open until you tick it.
5. Click “Allow”.

You go back to ChatGPT, and you can ask it about your books. The names of these menus can change from one version of the app to the next.

5. Choose what an app can read

Your choice of projects is for each app. It applies to every place where you connect that app: each computer, account or workspace. To change it, open Account → Connected apps, choose the app, and tick or untick projects. The change applies to the app's next request.

6. See what an app read

In Account → Connected apps, you can see when each app was last used and what it read.

7. What data an app can read

An app reads only the projects you ticked for it, and only when you ask it something. It can ask Journzy for:

• the list of the projects you opened for it, their books and their outline (parts, chapters and scenes), with your plan for each scene;
• the text of a scene;
• your story bible: characters, places, plot threads and your world entries, how they change through the story, and where they appear in the manuscript;
• searches in your manuscript and in the reference notes that you let AI read;
• the notes that Journzy's checks found, and your own comments (not comments from other people);
• the result of Journzy's writing checks on a scene: orthotypography, repetition, rhythm, clichés and readability. The checks are rules, not AI, and they save nothing.

It cannot read the projects that you did not tick, and it can never change anything.

8. Where your text goes

When you ask the app something, Journzy sends it the parts of your opened projects that it asks for. What the app does with that text follows the terms of the company that makes the app, for example Anthropic for Claude or OpenAI for ChatGPT. Journzy's promise not to train AI on your writing covers Journzy only. The privacy policy explains what Journzy keeps.

9. Disconnect an app

1. Open Account → Connected apps.
2. Click “Disconnect” next to the app.
3. Confirm.

The app loses access within a few minutes, and Journzy deletes its choice of projects a few seconds later. The next time the app asks Journzy for something, it asks you to sign in again. To use it again, connect it again from the app.

If the list shows an app as “Not connected”, it has no live connection to Journzy anymore, for example after 30 days without use. Click “Remove” to delete its choice of projects from the list.

An email about an app you did not connect? If Journzy tells you that an app connected to your account and it was not you, disconnect the app now. Then change your password on the Security tab.

10. How long a connection lasts

A connection ends by itself after 30 days without use, or 90 days after you approved it. The app then asks you to approve it again.

11. If something does not work

• The app says that it cannot read a book: the book is not ticked for that app. Tick it in Connected apps.
• The app asks you to sign in again: the connection ended. You disconnected it, or 30 days passed without use, or 90 days passed since you approved it. Approve it again.
• Journzy says that the connection request does not exist or has expired: start the connection again from the app. Each request is valid for a few minutes.
