What is Mythwrites?
Mythwrites is fiction writing software that connects a Book, Parts and Chapters manuscript with characters, worldbuilding, timelines, lineage and story intelligence in one project. It is a writing workspace for fiction across genres, not a chat assistant. See the connected novel-writing workflow ↗
How does it check story continuity?
Story intelligence relates supplied manuscript and world evidence to surface continuity findings, contradictions and canon proposals for you to inspect. It is an aid for review, not a guarantee that a story has no errors. Read about story continuity review ↗
Does Mythwrites rewrite my manuscript automatically?
No. Findings and canon proposals remain suggestions with review or dismiss controls. Your manuscript and canon change only when you choose to edit or accept something.
Can I use Mythwrites without AI?
Yes. AI is optional. The manuscript editor, worldbuilding, characters, relationships, timelines, lineage, maps, planning views, import and export all work without configuring any AI provider, and no AI runs unless you start one.
Can I use my own AI API key?
Yes. BYOK means bring your own key: you supply a credential for OpenAI or Anthropic, the two providers your browser can reach directly today. The key is held in your browser session storage and the request goes from your browser straight to that provider, so Mythwrites does not store it on our servers. Usage, limits and cost are governed by your own provider account.
Can I export my writing?
Yes. Mythwrites supports Markdown, JSON and DOCX export, plus full JSON backups and smart import for bringing existing work into the workspace.
Can I invite co-authors or beta readers?
Yes, on the Mythic plan. Collaboration invites use capability-based permissions, so you choose what a collaborator can reach, and read-only access stays clearly marked.
What does Mythwrites cost?
Draft is free forever: one real project, up to 25,000 manuscript words and 20 combined world entries, with export always available. Reaching a Draft limit does not delete or truncate your writing. Scribe is $4.99 per month and Mythic is $9.99 per month, billed monthly. There is no annual plan. Both paid plans include a 14-day free trial, and Paddle is the merchant of record. Compare plans ↗
Is Mythwrites only for fantasy writers?
No. It is built for fiction writing broadly. Fantasy-friendly fields such as lore, magic systems, races and factions are part of the worldbuilding toolkit, not a limit on the kinds of stories you can organize. See the worldbuilding workspace ↗
