Sudowrite

Sudowrite is an AI writing app for fiction: drafting, rewriting and feedback tools for novelists and screenwriters, sold on credit-based plans.

Sudowrite is an AI writing app for fiction, built for novelists, screenwriters and short story writers who work in long form. It is made by Sudowrite, an independent company founded in 2020 and based in San Francisco, and it is the only product that company sells. The app works inside the manuscript rather than in a separate chat window, so the AI reads what is already on the page before it suggests anything. The job it takes on is keeping an author moving through a long draft without leaving the text to go and prompt something else. Write continues the draft in the author's own voice, and Rewrite takes direction on a passage that is not working. Describe turns a place or a person into sensory detail, while Brainstorm returns lists of names, plot turns and complications to choose from. Story Bible holds the project itself: an outline, a first draft, characters, worldbuilding notes and a Canvas view for arranging them. Feedback reads a finished draft and leaves comments on the lines they refer to, each with a rewrite the author can accept or reject. Sudowrite Chat answers questions about the work in progress, and the plugin library adds custom AI tools that run on a selection or a chapter. Sudowrite suits a writer working alone on something long: a novel, a screenplay, a serial, or fiction written for a class. It fits authors who publish on a schedule and need a series to stay consistent, and it fits people who write for fun and want company at the blank page. It is built for one author at a time, with plans sold per account and no shared seats or team style rules. It is bought as a subscription, monthly or annually, metered in credits that refill each month, and the plan cards list every tier with its credit allowance. Sudowrite runs in the browser and keeps each book or script as a project, so drafts, notes and character cards stay in one place. Writers use it to turn an idea into an outline and then into chapters, to get past a scene that has stalled, and to sharpen description before a beta reader sees the draft. It writes in almost any language, matching the language of the text it is given. It stands on its own rather than plugging into a word processor or a browser extension, so the drafting, the revising and the feedback all happen in the Sudowrite editor.
