Sudowrite is an AI writing tool purpose-built for fiction rather than marketing copy or generic chat. Its Story Bible takes a writer from a loose idea through outline, chapter beats and full first draft in their own voice. Write acts like autocomplete tuned to a manuscript's characters, tone and plot arc; Describe adds sensory detail; Expand fixes rushed pacing; Rewrite handles line-level revision; and Feedback gives five actionable notes without needing beta readers. Under the hood, Sudowrite routes requests across multiple models — Anthropic's Claude, OpenAI models, open-source models and its own in-house fiction model, Muse — picking whichever fits the task. A visual Canvas for plotting, a Brainstorm tool for names and twists, Visualize for character/world art, and a library of 1,000+ community plugins round out the toolkit. Sudowrite claims no ownership over anything written in or generated by the app and does not train on user writing.

Read the full NovelAI review

NovelAI pairs an AI text generator tuned on literary and light-novel style prose with a separate anime-style image generator. Writers use its story mode to co-write open-ended text adventures and long-form fiction, while the image side produces anime character art, illustrations and book covers with tools like Vibe Transfer and multi-character prompting. It's a different shape of tool than a manuscript-focused drafting assistant — NovelAI leans into collaborative, open-ended storytelling and visual worldbuilding rather than structured outlining and line-by-line revision.
