Write with your AI, in your book.

1. Connect your AI app

Every app below uses the same address:

1. Claude (on the web, the desktop app and the phone): open the settings for connectors, add a custom connector, and paste the address. Claude sends you to MechaSquid to sign in and allow it.
2. ChatGPT: in the settings for apps and connectors, add a custom one with the address (ChatGPT may ask you to switch on developer mode first). You sign in to MechaSquid and allow it.
3. Other apps that speak MCP (Claude Code, Cursor, OpenClaw and others): add the address as a remote MCP server in the app’s settings. If an app cannot sign in, make an API key for one book in that book’s Settings, under Connect.

One connection reaches all your books. You see and disconnect every app on your Account page. How much an app may change by itself is yours to set in each book’s Settings; by default it proposes changes to your manuscript for you to accept.

2. Ask it something

Say “in MechaSquid” the first time, so it knows to use it. Copy any of these and change the names:

• Start a bookCopy

  “Start a new book in MechaSquid called The Salt Road. Give it a three-act shape: plan the chapters and a few scenes in each, with a line saying what each scene is for. Don’t write any prose yet.”

  Your assistant makes the book, its chapters and planned scenes. They appear in the Outline and on the Plot.

• Save an ideaCopy

  “I have an idea for a character: a ferry pilot who can’t swim and lies about it. Save it in my book.”

  It lands in Ideas, and shows up on the pages it mentions.

• Build the worldCopy

  “Describe the river town of Caldmoor for my wiki: what it looks like, who lives there, what it trades. Link the characters who live there.”

  A wiki page with links to the people and places it names.

• Plan what comes nextCopy

  “Read my outline and the last chapter. What should happen in the next chapter? Plan three scenes, and ask me before writing anything.”

  Planned scenes you can drag, rename or delete in the Outline.

• Check the storyCopy

  “Read chapter 3 and tell me if anything contradicts what happened before. Raise a flag for each problem rather than changing my text.”

  Flags you resolve or dismiss, each with the words it is about.

• Write in your voiceCopy

  “Read my writing brief, then draft the scene The Bent Nail from its plan. Propose it as a change I can review.”

  A proposed change on the scene: you accept, edit or reject it.

• Look something upCopy

  “Show me the page for Tobin Ashe.”

  In Claude and ChatGPT a small viewer opens in the conversation.
