Why Bookworm beats pasting chapters into ChatGPT, Grok, Gemini, or Claude
General chatbots are not a reader. Bookworm keeps illustrations, narration, Ask, and glossary inside the EPUB you own — spoiler-safe, synced to your place, without dumping whole books into a chat.
| Feature | Bookworm | ChatGPT / Grok / Gemini / Claude |
|---|---|---|
| Spoilers | Answers stay behind your reading position | Easy to spoil the ending by pasting ahead |
| Sync to your place | Illustrations, Ask, glossary, and narration follow the chapter you are on | No reading position — you re-paste context every time |
| Illustrations | Scene art painted from the words on the page, in six styles | Generic image prompts, not tied to your EPUB |
| Audiobook narration | On-demand chapter narration with lock-screen controls | No synced audiobook experience inside your book |
| Cost model | Credits for the chapters you generate — no subscription required to start | Subscription chat limits and usage caps |
