Sudowrite

Sudowrite is an AI writing partner made specifically for fiction. Instead of generic text, it helps novelists, screenwriters and fan-fiction writers brainstorm plots, draft scenes, add sensory description, rephrase tricky dialogue and keep characters consistent across a series. It runs on its own fiction-tuned models, Muse and Ballad, plus more than 30 leading models from providers such as Anthropic and OpenAI.

This review covers what Sudowrite does, Sudowrite pricing and the free trial, how credits work, privacy and ownership, and how it compares with ProWritingAid.

What Sudowrite does

• Write, Rewrite, Describe and Expand: continue a scene, rework a passage, add sensory detail or flesh out a moment with “story intelligence” that knows your characters and plot.
• Match your style: suggestions follow your voice instead of a generic AI tone.
• Series continuity: keep names, facts and timelines consistent across books.
• Brainstorm and outline: generate characters, plot ideas and outlines, and use an AI chat built for fiction.
• Developmental edits, line edits and beta reads on the Professional and Max plans.
• 30+ languages: write in almost any language and Sudowrite matches it, though some features may fall back to English.

Sudowrite pricing (2026)

Sudowrite has no free plan, but you can start a free trial with no credit card. Plans are priced in US dollars and use monthly AI credits:

• Hobby & Student: $10 a month billed yearly, 225,000 credits a month. For people who write for fun or for school.
• Professional: $22 a month billed yearly, with more credits plus developmental edits, line edits and beta reads. Good for a novel or screenplay.
• Max: $44 a month billed yearly, 2,000,000 credits a month, and unused credits roll over for 12 months. For authors who publish several times a year.

Yearly billing saves up to 50%; when we checked in early October, monthly billing cost $19, $29 and $59. Sudowrite’s “EZ Cancel Guarantee” lets you upgrade, downgrade, pause or cancel from your subscription page. See the official Sudowrite pricing page for current prices.

Is Sudowrite free?

Not permanently. There is a free trial with no credit card, which is enough to test Write, Describe and Brainstorm on a chapter of your own. After that you need a paid plan to keep using the AI features. If you cancel, you can still open and edit your projects; only the AI tools stop.

Privacy and ownership

Sudowrite says it claims no rights over anything you put in or anything it generates for you, and it does not use your writing to train its own or OpenAI’s models. It also states that it won’t plagiarize unless forced to with copied text, and it encourages you to run plagiarism checks to be sure.

Sudowrite vs ProWritingAid

They work well together. Sudowrite helps you generate and develop a story; ProWritingAid helps you edit it with grammar checks, 25+ style reports and manuscript analysis. If you only want cleaner prose, Hemingway Editor is a simple option. Compare: Sudowrite vs ProWritingAid vs Hemingway.

Who Sudowrite is for

Sudowrite is for fiction writers: novelists, short-story and fan-fiction writers, screenwriters and students in creative writing. It is not designed for blogs, business copy or academic essays. Sudowrite positions itself as a creativity partner rather than a ghostwriter; check any publisher, contest or school rules on AI use. See more AI tools for authors.
