About "Sudowrite"

How to Use

  1. Create an account

    Create an account on the official site (sudowrite.com). A free trial with no credit card required is available.

  2. Create a project (work)

    Create a new work and open the writing editor. You can manage the works you want to create, such as novels, short stories, and screenplays.

  3. Solidify your setup in the Story Bible

    Enter ideas, characters, world-building, and a synopsis into the Story Bible, then progressively break them down into an outline and the structure of each chapter.

  4. Write with Write / Expand / Describe

    Use Write to have it suggest the next passage (about the next 300 words) from multiple options, Expand to flesh out rushed scenes, and Describe to add scene-setting, advancing your writing.

  5. Polish with Rewrite and Feedback

    Try alternative phrasings with Rewrite and refine your work while understanding improvement points with Feedback. Generation consumes credits.

Pros and Cons

Pros

  • Specialized in novel and fiction writing, with a rich set of creative-specific features such as passage suggestions and scene-setting
  • The Story Bible lets you progressively build everything from ideas to chapter structure
  • Brainstorm lets you generate unlimited ideas for names, settings, and more
  • You can try it without a credit card

Cons

  • The interface and optimization are primarily in English, making Japanese writing effectively close to unsupported
  • Because it uses credits, long works or heavy use consume a lot
  • It is specialized for creative (fiction) writing rather than general business documents or SEO articles

Reviews and Reputation

  • Novelists and creators praise it: "Idea generation and next-passage suggestions keep my pen moving" and "the Story Bible makes it easy to structure a long work."
  • Users say "Describe expands my range of description" and "it's an excellent sounding board."
  • On the other hand, some point out that it "assumes English and requires workarounds for Japanese writing" and that "credit consumption can be fast in some situations."

Frequently Asked Questions (FAQ)

Q. Can I use Sudowrite for free?

A free trial with no credit card required is available. For continued use, you subscribe to one of the monthly plans—Hobby & Student, Professional, or Max (credit-based).

Q. Does it support Japanese?

The interface and the optimization of each feature are primarily in English, and at present it effectively does not support Japanese writing. The community shares workarounds for multilingual use (such as specifying the language in the Story Bible), but behavior can be unstable in languages other than English, making it unsuitable for serious writing in Japanese.

Q. Who is it for?

It is for authors and creators who write novels, screenplays, and fiction. It suits people who want to advance the entire creative process—from idea generation to writing and revision—together with AI.

Q. What are credits?

They are points consumed each time you use a generation feature such as Write, Describe, or Brainstorm. Each plan has a set number of credits per month, and longer works or more generations consume more.
