NovelSpell Remix gives classic novels a fork button.

Before this hackathon, NovelSpell already sold classic books, and this week I built Remix: a fork button for the classics.
- All of Remix was built October 26 – November 4, 2026, for the Meta Global AI Developer Hackathon, on public-domain texts. NovelSpell's store, books, covers, pipelines and code are not part of it. The app only links out to novelspell.com.
- Every model the app calls at runtime is a Meta model: Muse Wonder writes each chapter and Muse Image draws each comic page, through the Meta Model API. In Fast mode (the reader's toggle) Muse Spark Open, Meta's open-weights model, writes the chapter instead, served by Baseten.
- Code written with Claude and Codex assistance.

The problem: fan fiction is one of the biggest kinds of reading online (Archive of Our Own alone hosts over 18 million works), and "what if" is its favourite question. A general chatbot is not given the book's state at the moment you pick: who knows what, and when. Remix gives the model that state.

What Remix does: every book is mapped first. The map holds the cast and their motives, the timeline, who knows what at each point, the world's rules and the turning points where the story can split. A reader picks one of ten public-domain classics, picks a turning point and asks "what if". The moment they press Write, Muse Image starts the cover of the forked book, with a title it invents. Muse Wonder plans the chapter in six events, and the moment that plan is complete, Muse Image starts drawing the chapter as one multi-panel comic page while Wonder streams the prose in the author's voice, written from the book's state at that moment. The reader can revise in plain words (a separate revision step decides what the request reaches and is asked to keep the rest word for word), with every version kept in their browser, open the original chapter to compare, share the remix, or press "Make it a full novel": NovelSpell can write a full novel inspired by this chapter.

Who it is for: readers and fan-fiction writers who want to play inside a book they love. For Frostwave Labs, it is a new front door to a bookstore that is already live. Its AI publishing pipeline publishes 72 titles (25 original novels it wrote, 47 classics) in 21 languages: 1,512 language editions and 4,533 sellable SKUs.
