Sudowrite is an AI writing app built specifically for novelists and fiction writers, not general content. Its Write, Rewrite, Describe, and Brainstorm tools are all story-aware — they analyze your characters, tone, and plot arc instead of generating generic text.

Story Bible takes a project from idea to outline to chapter beats to full drafts in your own voice. Write suggests the next few hundred words based on your characters and plot arc, Describe and Expand help with vivid detail and scene pacing, and Rewrite/Feedback handle revision. Canvas is a visual space for planning plot points and character arcs, and the platform runs on Muse and Ballad, Sudowrite's own fiction-specific models, alongside 30+ industry models.
| Plan | Price | Credits/month |
|---|---|---|
| Hobby & Student | $10/mo | 225,000 |
| Professional | $22/mo | 1,000,000 |
| Max | $44/mo | 2,000,000 |
Where it holds up: dedicated fiction models (Muse, Ballad) and Story Bible take a project from idea to full drafts in the author's own voice, with an EZ Cancel Guarantee and no credit card needed for the trial.
Where it falls short: there's no permanent free plan, and developmental edits, line edits, and beta reads are reserved for the $44/mo Max plan.
For another AI book-writing tool, see Squibler — both are covered in our Best AI Tools for Writing & Publishing a Book collection.
Is Sudowrite free to use? There's a free trial with no credit card required. Paid plans start at $10/month.
Does Sudowrite own what I write? No, Sudowrite claims no rights over anything you write or anything it generates, and does not use your writing to train its models.
Is Sudowrite only for fiction? Yes, it's purpose-built for novels and screenplays — its tools (Story Bible, Canvas, Muse/Ballad models) are designed around plot, character voice, and pacing rather than general content.
