Sudowrite is an AI writing tool founded in 2020 and designed exclusively for creative fiction writers. Built by writers who were frustrated by the generic prose of general-purpose AI tools, Sudowrite understands genre conventions, narrative structure, and the craft of storytelling in a way ChatGPT does not by default. It has been used by published novelists, screenwriters, and game writers as an active creative collaborator — not just a text generator.
Sudowrite's toolkit goes beyond basic generation. The Describe feature expands a scene using all five senses. Rewrite offers multiple stylistic alternatives for a paragraph. The Brainstorm tool generates plot twists, character motivations, and story beats. Story Bible maintains a persistent document of your world's rules, characters, and timeline to keep AI output consistent. The Write feature generates prose in your established voice using the current scene context. These features are not available in general-purpose tools — they require training on what makes narrative prose work.
Novelist and fiction authors who want a collaborator that understands plot structure, character arc, and genre conventions. NaNoWriMo participants using AI to meet 50,000-word targets without losing narrative coherence. Screenwriters brainstorming story possibilities before committing to a direction. Game narrative designers building branching dialogue and world lore. Anyone frustrated with how general AI tools produce flat, ungenerous prose for creative projects.
Sudowrite's Hobby plan is $10/month for 30,000 words/month — enough for regular short story writing or early-stage novel drafting. Professional is $25/month for 90,000 words/month. Max is $100/month for 300,000 words, suitable for prolific novelists or series writers. All plans include a 3-day trial for $4.88.
Sudowrite is single-purpose: if you need it to write marketing copy, product descriptions, or business content, it will disappoint. Word limits on the Hobby plan stall active novel writers quickly. The small team means bugs sometimes linger longer than they should. Support response time is slower than enterprise tools.
Sudowrite pays 25% recurring commission for the first 12 months of each referred customer via Rewardful. The creative writing niche is underserved by most AI tool affiliate content — there is genuine SEO opportunity for content targeting fiction writers.
For creative fiction writers, Sudowrite is the best-purpose-built AI writing tool available. It understands story in a way no general tool matches out of the box. The $10/month Hobby plan makes it an easy trial. Not for business writing — full stop.
