There is no free plan. Sudowrite offers a free trial with no credit card required, after which the paid plans run from $10 to $59 per month depending on tier and billing cycle.

Do Sudowrite credits roll over?

Only on the Max plan, where unused credits roll over for up to 12 months. On Hobby & Student and Professional, unused credits expire when the monthly allowance refreshes.

Does Sudowrite own or train on my writing?

No. Sudowrite states that it claims no rights over anything you write or generate in the app, and that your writing is not used to train its models or OpenAI's.

Which AI models does Sudowrite use?

Dozens, including its in-house fiction models Muse and Ballad, the latest Claude models from Anthropic, several OpenAI models and open-source models. Credit cost per generation depends on the model chosen and how much context is sent.

Sudowrite 是什么？

Sudowrite is a web app built only for fiction, founded in 2020 by Amit Gupta and James Yu. It walks a book from premise to finished chapters: the Story Bible holds your synopsis, characters, worldbuilding and outline, and tools such as Write, Describe, Rewrite and Brainstorm generate or expand prose from that context. Its own fiction-tuned models, Muse and Ballad, sit alongside dozens of others — including Anthropic's Claude and OpenAI models — all drawing on a single pool of credits.

The features map to stages of drafting rather than a blank chat box. First Draft turns an outline beat into a scene, Feedback returns developmental edits, line edits and beta-reader-style critique, and the Story Engine tracks chapter continuity across a long manuscript. Finished work exports to DOCX. Sudowrite suits novelists and screenwriters who want AI help inside a structured manuscript workflow, and who accept metered credits instead of flat, unlimited generation.
