Write your book by chatting in ChatGPT.
Connect BookWriter to ChatGPT and finish a real book the way you already work — in conversation. You steer, the AI drafts, and every word you write is kept verbatim.
How to connect & set up
ChatGPT connects as a developer-mode MCP connector. Paste one Server URL, authorize over OAuth, and you’re writing.
Your Server URL
https://www.bookwriter.vip/api/mcp/v1ChatGPT requires a public https URL (not localhost) and signs you in over OAuth — no token to paste. If a client ever asks for a Bearer token instead, grab one on your connection page.
- 1In ChatGPT, open Settings → Connectors and turn on Developer mode (available on Plus, Pro, Business, and Enterprise; currently in beta).
- 2Go to Settings → Connectors → Create and paste the Server URL below.
- 3Authorize when prompted — ChatGPT signs you in over OAuth, so there is no token to paste. Sign in with your BookWriter account.
- 4In any chat, click + → Developer mode → pick BookWriter.
- 5Say “Start a new book” and follow the prompts.
The write-a-book loop
Set up the book, write a seed paragraph, hand it off, sharpen, accept — then repeat. Your words are never overwritten.
- 1
Set up the book
Tell ChatGPT your premise and length. create_book spins up a real project — title, word target, chapter plan — not a blank prompt box.
- 2
Write a seed paragraph
Type a paragraph or a few lines to open the chapter. Those words are your seed, kept exactly as you wrote them.
- 3
Hand it off
handoff lets the engine finish the chapter in your voice, built around your words — your sentences are kept verbatim, never overwritten.
- 4
Sharpen, then accept
sharpen nudges the draft lighter or stronger until it reads right. accept_chapter locks it in and you repeat for the next chapter.
