Documentation

Calliope is a writing app, an MCP connector for your own AI client, and a plain HTTP API over your manuscript — three ways to work, one canon. Everything below is drawn from how the product actually behaves.

The app

For writers

Everything the editor and the surrounding app can do — the writing surface, structure, the Map, marginalia, the AI companion, goals, and export.

The MCP connector

For connecting an AI client

Connect Claude, ChatGPT, or Cursor to your manuscript — what your agent can read, augment, and never touch, and what it costs.

The Writer API

For scripting your own book

A plain HTTP/JSON API over your own manuscript, authed by a personal key — for your own scripts, and the LLMs you hand a prompt to.

The writing is yours. Keep it that way.

Calliope is the AI companion for writers who want help thinking — not typing.
