Sudowrite
A fiction-writing assistant that drafts scenes, suggests alternates for a stuck sentence, and tracks characters across a manuscript.
What you'd use it for
Getting past a stuck scene or blank page in a novel or screenplay with tools built for fiction craft specifically, not a general writing assistant repurposed for it.
- Generate a scene draft from a rough outline with Story Bible and Expand
- Get several alternate continuations for a sentence or paragraph you're stuck on with Write
- Keep characters, plot threads and worldbuilding details straight across a long manuscript with Story Bible
- Get craft-level feedback on a chapter's pacing and prose with Feedback
- Turn a scene or character description into reference artwork with Visualize
The verdict
Worth it if you're actually writing fiction and getting stuck is the recurring problem — the tools are built around scenes, characters and prose craft rather than generic text generation. The credit system means cost tracks how much you generate, which rewards a writer who drafts sparingly and edits by hand, and punishes one who leans on it for every paragraph. It won't outline or finish the novel for you, and it isn't trying to: treat it as a tool for pushing past a blank page, not a co-author.

What you need to start
- An email address or Google account to sign up
- A paid plan from $10/month once the free trial's credits run out
A few minutes to create a free account with no credit card needed; most people are looking at a paid plan within the first real drafting session once trial credits are used up.
Your first run Sign up with an email or Google account and you're in the editor with free trial credits already loaded, no credit card required. Paste in a paragraph or outline and run Write or Expand to see a generated continuation within a couple of minutes, though the trial credits are enough to test the tools, not to draft a full chapter.
Where it breaks
Sudowrite runs monthly and yearly billing with up to 50% off on yearly plans, but the exact yearly figure wasn't shown without selecting a plan first — the monthly prices above are the ones confirmed on the page.
Browser-based editor. Uses a mix of models, including Anthropic's Claude, open-source models, and an in-house fiction model called Muse.

When not to use it
A business operator writing emails, proposals or web copy gets nothing here that a general assistant like ChatGPT or Claude doesn't already do more cheaply. Also not for a fast drafter who generates constantly, since the credit pool on the cheaper tiers empties quickly at that pace.
This is not a general writing tool wearing a fiction hat — Sudowrite was built for novelists and screenwriters specifically, and it shows in the feature names: Brainstorm for getting unstuck, Expand for turning an outline into a rough draft, Write for pushing through a scene when the words won’t come.
The credit system is the thing to understand before picking a tier. Every generation — a paragraph, a beat, a description rewrite — draws down a monthly credit pool rather than a hard cap on documents or words, so a slow, careful writer on Hobby & Student may never hit the ceiling while a fast drafter on the same plan burns through it in a week.
It won’t plot your novel for you, and it says so plainly in its own FAQ: this is a tool for getting past a blank page and a stuck scene, not a ghostwriter that hands you a finished manuscript. The company also states it does not train on what you write, which matters if the manuscript is unpublished and you’d rather it stayed that way.
Next to a general assistant like ChatGPT or Claude, the difference is depth in one genre: Sudowrite knows fiction craft the way those tools know everything a little.
