ChapterPlay - Playable Previews for Indie Authors

A tool for self-published romance and fantasy authors to spin off a 15-minute playable game from their upcoming book as a viral marketing hook on TikTok and BookTok.

Target user

Self-published romance and fantasy authors launching a new book

Features
  • Paste your manuscript chapter and pick a hero, conflict, and visual mood
  • Auto-generate a 15-minute web game with your book's world and a teaser ending
  • BookTok-ready share link with a QR code for the back of your paperback
  • Email capture: 'Want the full novel? Get notified' embedded in the game's ending
Why now

Self-published authors spend thousands on BookTok ads; a 24-hour-turnaround playable preview is a new, cheap hook for a category that already thrives on viral gimmicks.

Demand
6/10

BookTok drove ~59M print sales and ~$760M US revenue in 2024; indie authors actively buy marketing tools like AuthorScale ($19.99/mo) and pay for TikTok ads, showing real willingness to try new hooks.BookTok for Authors: How TikTok Is Driving 59 Million Book SalesPricing - AuthorScale | Affordable Plans for Author Marketing

Crowded: Storio AI, Rosebud visual-novel maker, Gameer, Combos, Episode (150K stories), Spotlight, and Wattpad interactive all already turn stories into playable experiences — and Rosebud explicitly markets romance/sci-fi templates. The specific 'playable book preview as BookTok ad' niche is narrow.Storio AI - Interactive Story Creation - AI Powered by storioaiFree Visual Novel Maker — Create Visual Novels Online, No Code - RosebudEpisode - Choose Your Story - Apps on Google Play

Monetization
5/10

Indie authors do pay ($19.99/mo for AuthorScale, hundreds–thousands on TikTok Spark Ads), but this is a one-off per-book product rather than SaaS, and the category (AI-generated game preview) is unproven — high churn risk and price-sensitive buyers.Pricing - AuthorScale | Affordable Plans for Author MarketingTikTok Ads for Books — Real ROI Math for Indie Authors in 2026

Longevity
6/10

ScribeCount reports BookTok 'matured rather than peaked' in 2026, interactive fiction (Episode, Wattpad) is a decade+ established medium, and AI novel-to-game pipelines are a current trend — but the specific 'playable teaser' gimmick likely has a 2–3 year novelty window before saturation.TikTok for Indie Authors: BookTok, TikTok Shop, and Discovery in 2026Episode - Choose Your Story - Apps on Google Play

Feasibility
4/10

A novel-to-game skill pipeline exists (referenced GitHub repo at 75 stars), but 24-hour production of a polished, romance/fantasy-toned playable teaser that's embeddable on TikTok and won't embarrass the author is a non-trivial UX, art-pipeline, and QA challenge.Storio AI - Interactive Story Creation
