The AI writing studio
Write books with an assistant that remembers every thread.
Folio is a calm, chat-based studio built for long-form fiction. Draft and rewrite with the right model for each task, keep a living story bible that tracks your characters and canon, and generate covers and character art — all in one place.
Chat tuned for prose
Draft, continue, and brainstorm in a conversation that understands scenes, chapters, and voice — not just messages.
Highlight to rewrite
Select any line and reshape it — tighten, expand, shift POV or tone — then accept the change with a clean diff.
A living story bible
Characters, places, and canon facts are tracked automatically, with continuity warnings before a contradiction reaches the page.
Covers, portraits & audio
Generate character portraits and book covers, and listen to your chapters read aloud — or dictate the next scene by voice.
