Sudowrite
An AI writing partner built around fiction, from Story Bible to draft.
About
Sudowrite is an AI toolkit built for fiction writers. It organises a novel through a Story Bible of braindump, synopsis, characters, outline and scenes, then drafts, continues, rewrites and describes prose with its own fiction models and other leading models. Every plan includes the full feature set; plans differ only in monthly credits.
Key features
- Story Bible that keeps characters, plot and world details in context
- Write and Guided Write for drafting and continuing scenes
- Rewrite, Describe, Brainstorm and Expand tools for revision
- Draft mode for generating longer passages from an outline
- Chat and Feedback for discussing and critiquing your manuscript
- Plugins, series support and mobile companion apps
Pricing
Hobby & Student $19/month ($10/month billed annually); Professional $29/month ($22 billed annually); Max $59/month ($44 billed annually)
Prices from the official pricing page as reported in 2026; published sources disagree on Professional's credit allowance (450,000 vs 1,000,000), so confirm credits at checkout.
Best for
Novelists and fiction writers who want an AI partner for planning, drafting and revising stories.
Limitations to know
AI output can be wrong or inconsistent with your story, so check names, plot details and continuity before keeping generated prose. Credit costs also vary sharply by model, so a large model can burn a month's allowance far faster than a small one.
What users like
- Story Bible keeping characters, plot and world consistent across long stories
- Revision tools that improve a writer's own prose rather than replacing it
- Full feature set on every plan, with no key tools locked behind higher tiers
What users complain about
- Credit costs varying sharply by model, draining allowances faster than expected
- Generated prose sometimes generic or needing heavy editing for distinctive voices
- Occasional continuity slips despite the Story Bible
