Why Erotica Writers Give Up on Most AI Tools

Adult fiction needs a tool that respects both the genre and the author.

Refusals mid-scene

Mainstream AI tools stop at the bedroom door, however the story is set up.

Generic smut

When they do write it, the scenes sound interchangeable and nothing like you.

No control over heat

It is all or nothing, with no way to set how explicit each chapter should be.

Series continuity

Relationships, histories and dynamics get lost between books.

See a chapter written at the author's chosen heat level and in their voice.

From Idea to Finished Spicy Book

Write, edit, format and publish, with the heat level and the voice set by you.

1.Write

Set the heat and the voice

Turn explicit content on for the book, set each chapter's explicit share in its story bible, and paste a sample of your writing so every scene sounds like you. Choose a model that handles mature scenes well.

  • Paste 6 to 10 paragraphs of your own writing and every chapter follows that style
  • Import a Word .docx of up to 200,000 words without a line of it rewritten
  • An outline, characters and chapters you can reorder, edit or rewrite
  • Choose the model for each chapter: Gemini, Claude or Grok
  • Standing instructions for the book, extra instructions for any chapter

2.Edit

Edit without losing yourself

Editing keeps your voice and leaves every decision to you. Ask for a change and see it as a diff, or run the Book Editor for an editorial letter, line edits and a proofread you review suggestion by suggestion.

  • Chapter chat shows every change as a diff you accept or reject
  • Book Editor: an editorial letter, a style sheet, line edits and a proofread
  • Every suggested replacement is accepted or rejected one by one
  • AI proofreader with several fixes to choose from for each issue
  • Edit any line yourself in the editor, whenever you like

3.Format

Format it like a real book

Pick an interior theme, a body font and a trim size in the book formatter, and export a print PDF, an EPUB and a DOCX that look professionally set. Design the cover in the same place.

  • Five interior themes and 12 embedded body fonts
  • Nine trim sizes, with front and back matter built in
  • Print PDF, EPUB and DOCX, with EPUB validation
  • A cover at the 1840 x 2784 KDP ratio, or upload your own
  • An audiobook made from the same manuscript

4.Distribute

Distribute it under your name

Take the files to Amazon KDP or any other store. The KDP extension fills the Details, Content and Pricing pages while you review each one. Share one Author Page link and collect the emails of readers who want your next book.

Coming from Sudowrite?

Sudowrite is a strong tool for mainstream fiction, and it refuses most explicit scenes. If you write adult fiction, read the side-by-side on voice control, explicit-content settings and publishing.
