Everyday AI

Which tool or AI should I use to write a book?

Write the book in a writing app and use AI as an editor, not the author. Reedsy Studio is free for drafting and formatting, and exports print-ready PDF and EPUB files; Scrivener, with a free trial, for Mac or Windows, keeps chapters, notes and research together for a long book; Google Docs is enough for a short one. For AI help, paste a chapter into Claude, ChatGPT or Gemini and ask for a critique of pacing, clarity and continuity. Sudowrite is built for fiction writers, from $10 a month, and Novelcrafter plans characters, outline and series from $4 a month, adding AI from $8 with your own key. If you publish through Amazon's Kindle Direct Publishing you must declare AI-generated text, images or translations, though not AI-assisted editing, and text a model wrote on its own is generally not something you can copyright. Rule: draft in Reedsy or Scrivener, ask AI for feedback, and keep the sentences your own.
