Muse & model choice

AI built around the craft of fiction.

Muse is Sudowrite’s AI model built for fiction, with dialogue, pacing, viewpoint and descriptive detail at the center of its design. Genre and style instructions give the work a direction; your story material supplies the substance.

Muse, Ballad and other available models give you a choice of what powers the prose.

Story Bible · Scenes · Draft

An outline that becomes a working draft.

Story Bible brings premise, genre, style, characters and worldbuilding into one connected plan. The outline leads into Scenes, where chapter events, viewpoint and extra instructions become the basis for drafting prose.

Draft draws on the characters and worldbuilding referenced in those scenes, along with genre and style. A plan can become a chapter draft without moving your story material into another tool.

Story-aware Chat

A writing conversation that can change the manuscript.

Chat works with your active document and enabled Story Bible, so a conversation about motive, structure or a revision can draw on the story already in the project. Series context can bring the other books into that conversation, too.

With Allow edits, Chat can create and revise documents, update story notes, leave comments and highlight passages. For changes that span several steps, it proposes a plan for you to review and adjust before the work begins.

Chat-only conversation uses no credits. Allow edits uses credits.

Feedback & AI beta readers

Fresh editorial angles, right in the margins.

Feedback reads the manuscript alongside Story Bible and places its notes beside the text. Developmental, line, dialogue and copy-editing modes give different kinds of attention to the draft; custom feedback types let you focus the review.

Three AI beta-reader perspectives cover emotional impact, structure and motivation, and plausibility. You can discuss a comment with Chat, then apply or dismiss a proposed edit without leaving the manuscript.

Feedback is available on Professional and Max plans only.

Series support

One story world, across the series.

Books in the same Series folder share characters and worldbuilding, with access to each other’s outlines. Changes to those shared details carry across projects, giving the next installment a working foundation in the world you’ve already built.

Shape the prose at the level it needs.

Write

Keep a passage moving.

Continues from the prose at your cursor, using preceding text and enabled story context. Auto offers a continuation; Guided takes your direction for what should happen next.

Describe

Give the scene a sensory life.

Suggests sensory language and metaphors for a selected word or phrase. Choose the senses you want to explore, then keep the details that belong in the passage.

Expand

Give a compressed moment more room.

Builds out selected prose with fuller action and detail, drawing on nearby text and story context.

Rewrite

Change the telling.

Offers alternative phrasing for selected prose, from a tighter version to greater intensity or inner conflict. Preset approaches and custom instructions let the revision follow your intention.

Accepts up to 6,000 words at once.

Quick Edit

Review the change where you write.

Takes natural-language instructions and edits a selection inline, with the original visible for comparison. Accept, reject or refine the changes in place.

Up to 1,000 words. Standard mode uses no credits; High Quality mode uses credits.

Plugins

Build a writing tool around your process.

Sudowrite’s library offers more than 1,000 plugins for work such as editing, analysis, feedback and marketing.

Describe what the plugin should do to create it without writing code. More advanced controls let you choose models, pass in Story Bible details and build tools with several stages.

More tools inside the studio.

Canvas

A visual home for notes, character arcs, references and plot development. Move cards around, explore alternative directions and generate outlines in a flexible two-dimensional space.

Brainstorm

Generates options for names, titles, plot turns and world details from your seed material. Save promising choices to a Keepers List and steer further suggestions with what you keep.

Uses the context supplied in Brainstorm, rather than reading Story Bible.

Characters & Portraits

Develop personality, backstory, dialogue and physical appearance in editable character records. Portraits turns a character’s Physical Description into images in four styles, with a gallery for different looks.

Visualize

Generates an image from a descriptive passage selected in your document. It makes character and setting descriptions visible; Portraits works separately from the character record.

A workspace for the book

Keep drafts and chapters organized inside projects, switch to full-screen focus mode and choose a theme or dark mode that suits the writing session.

Word choice, close at hand

The integrated thesaurus offers alternative words inside the editor, keeping sentence-level choices close to the prose.

Writing fit

Where Sudowrite fits in a writing project.

  • Context handling differs by tool; review generated prose against your intended voice, story facts, and enabled context. Brainstorm uses its own inputs rather than the Story Bible.
  • Draft length follows the numbered scenes rather than an exact chapter word-count setting.
  • Chat only does not use credits; Allow edits does. Feedback requires Professional or Max.
  • Mobile includes Write, Rewrite, Chat, and Smart Dictation, with Story Bible generation through Chat; the web app has the fuller toolset and document history.
