Connect ChatGPT To Write

What connecting means

Write can work alongside an AI assistant. Once connected, the assistant can do in your books the kinds of things you do—read a chapter, draft or revise a scene, keep notes, look something up in the codex, build a PDF—when you ask it to. It signs in as you, so it sees only the books you can see, and nothing in them changes unless you ask for it.

Connecting takes a couple of minutes, and you only do it once per app.

Connect ChatGPT via the your web browser

  1. Click your profile icon in the lower left and choose Settings.

  7. ChatGPT will validate that it can connect, and then show you a connection button for you to continue to our site

About the permission screen

When you allow access, Write is granted both reading and writing in one step; there isn't a read-only option at the moment. If you'd rather an AI only looked and never changed anything, the simplest way is to say so in your conversation—and know that whatever it does is saved in your book's history, where you can see it and undo it.

If something doesn't work

  • The sign-in page wants a password you don't recognize. It's asking for your Author Tools account, not your Claude or ChatGPT account.
  • The connector sits there saying "not connected." Usually the address was mistyped. Remove it and add it again, copying the address from this page.
  • You signed out of Author Tools in your browser and expected the AI to stop. It won't—the connection has its own sign-in. To stop it, see Disconnect an AI.
