Is Sudowrite free to use?
Sudowrite offers a free trial with no credit card required, but ongoing use requires a paid plan starting at $10/month. You can still access your projects after canceling, but AI features require an active subscription.
Does Sudowrite plagiarize or copy other writers' work?
Sudowrite says it generates text one word at a time based on patterns rather than copying verbatim, so plagiarism is extremely unlikely unless you explicitly feed it copyrighted text. They encourage running outputs through plagiarism checkers to verify.
Who owns the writing produced in Sudowrite?
You own everything. Sudowrite explicitly claims no rights over what you put in or what the AI generates for you.
What AI models does Sudowrite use?
Sudowrite uses a mix of Anthropic Claude models, OpenAI models, open source models, and its own in-house fiction model called Muse. These are paired with proprietary narrative processing layers.
Does Sudowrite work for non-fiction or business writing?
Sudowrite is explicitly built for fiction — novels, short stories, and screenplays. While you could technically use it for other writing, its features (Story Bible, character arcs, plot tools) are designed for narrative work.
How much does Sudowrite cost for a typical novelist?
Most novelists will want the Professional plan at $22/month, which includes 450,000 credits — enough for novel-length work. Yearly plans offer up to 50% off.
Does Sudowrite use my writing to train its AI?
No. Sudowrite states they do not use your writing to train their models or OpenAI's models.
What languages does Sudowrite support?
Sudowrite supports 30+ languages for the Write feature, matching your input language. Some other features may fall back on English when the model is uncertain.
