What is Sudowrite?

Sudowrite is an AI writing assistant designed specifically for fiction authors, made by a team of writers focused on narrative-driven projects. The platform operates on a freemium model and uses Muse 1.5, a custom language model trained on storytelling rather than general text generation.

The tool provides several core features for novel writing. Write generates contextual suggestions of up to 300 words based on character voice, tone, and plot arc—functioning as an advanced autocomplete. Describe helps authors develop atmospheric scene details without slowing pacing. Expand lengthens rushed sections by building out existing scenes while maintaining narrative momentum. Rewrite offers flexible sentence-level revision with multiple options generated on demand. Canvas serves as a planning interface where authors explore plot points, character arcs, and themes, with the system suggesting alternate plot twists and character secrets. Story Bible guides users from initial concept through outlining, chapter breakdown, and full draft composition. Brainstorm generates names, titles, items, and worldbuilding elements with feedback-based learning. Feedback provides three actionable revision suggestions after analyzing a complete draft. Visualize generates character art and worldbuilding illustrations from written descriptions.

The interface includes a distraction-free writing environment with customizable themes, dark modes, and full-screen focus mode. Projects organize chapters and drafts hierarchically. Sudowrite works with the user's existing style and voice rather than imposing a single tone.

The platform has attracted endorsements from published authors including Hugh Howey (Silo series), Bernie Su (Emmy-winning screenwriter), and Chris Anderson (New York Times bestselling author). Pricing includes a free tier with limited monthly usage and paid subscription plans offering expanded feature access and generation limits.
