Where Claude is stronger

  • A frontier model with a very long context that can read a whole manuscript in one pass.
  • Claude Code has full autonomy over a local folder: scripts, git, any tool.
  • Generous usage on the higher plans for heavy drafting.

Where Authr is different

  • A structured workspace (manuscript tree, codex that tracks mentions automatically, graph, timeline, plot grid) instead of loose files.
  • Several agent roles that comment and suggest edits you accept or reject, with version history.
  • One place where you, your co-writers and every agent review the same changes.

Use both

Add Authr as an MCP server in Claude Code with one command, or to Claude Desktop through a small bridge. Claude then reads the book, drafts scenes, files suggestions and answers comments, and it doesn't touch your in-app agent allowance.

Questions

What's the main difference between Authr and Claude?

Claude writes beautifully and can read a whole manuscript at once, and Claude Code can work through a folder of chapters. What's missing is the book around it: structure, a story bible, review and approval. Authr is that book, and Claude connects to it over MCP in one step.

Does this work with Claude Desktop?

Yes, through a bridge such as mcp-remote that sends your Authr API key as a header. The Claude Code guide shows the config.

How do I connect Claude Code?

Run the one-line claude mcp add command with your Authr API key. The step-by-step guide walks through it.

Is Authr free?

Yes. The Free plan has every feature and unlimited books, with about 15 agent tasks a month for in-app agents. Agents you connect over MCP or the API are unlimited on every plan. Pro is $19 a month and Studio $49.
