Who each one is for

Pick StoryStepper if you want something to read

You want a new romance, mystery, thriller, fantasy, drama, comedy, horror or crime novel shaped around your answers, and you have no wish to write it yourself. You choose the shape, the ending and the feel; the book is planned in full, checked for continuity and delivered within the hour. If you would rather read one chapter each morning, Stories does that.

Pick Sudowrite if the book is yours to write

Sudowrite is made by writers for writers, and it is one of the most complete AI tools for fiction. It can match your style, take an idea step by step to an outline and chapters with Story Bible, keep continuity across a series, suggest the next passage when you are stuck, expand a rushed scene and give feedback on a draft. If you are the author, it is the better choice.

The main differences

01

Author or reader

With Sudowrite you are the author: every sentence passes through your hands and your judgment. With StoryStepper you are the reader: you give a brief, then read the finished book.

02

A finished book or a better draft

StoryStepper plans the whole book first, critiques and refines the plan, writes the manuscript in one sitting and audits it for continuity. Sudowrite works passage by passage inside your manuscript, so the result is as finished as you make it.

03

Plans built around different things

Sudowrite plans are built around AI credits for writing work. StoryStepper plans are built around books: two a month on Books, five on Books+, or one living story plus one book a month on Stories.

04

Reading privately, or with friends

Nothing you read on StoryStepper is public. If you want company, an invite-only reading circle lets up to five friends read along.

Questions about StoryStepper and Sudowrite

Is StoryStepper an AI writing tool like Sudowrite?

No. StoryStepper does not help you write a manuscript. It writes a complete short novel for you to read, from six answers you give, and delivers it within the hour.

Can Sudowrite write a whole novel for me?

Sudowrite’s Story Bible takes a writer step by step from idea to outline to chapters, but it is designed for you to stay the author: you steer, edit and decide. If you want a finished book without doing that work, StoryStepper is built for that.

How much does each one cost?

StoryStepper Books costs $2.99 the first month for new subscribers and includes two complete books a month. Books+ includes five books a month, Stories is $15.99 a month, and a single book without a plan is $5.99. Sudowrite offers a free trial and monthly plans with AI credits; their pricing page has current prices.

Books and Stories are written in English, Spanish, Portuguese (Brazil) and Italian.

Can I use both?
