AI providers
Last changed: November 10, 2026
Character chats, stories, recaps, translations and book analysis are generated by AI models run by the companies below. When you use these features, the app sends the data listed here to them through our server. This page always shows the providers in use right now; our privacy policy explains the rest.
Who receives your data
| Provider | Used for | Privacy policy |
|---|---|---|
| Anthropic | Reading the books you import: characters, scenes and summaries Replies from characters and the book chat, and stories Translating passages you select while reading | Anthropic privacy policy |
What is sent
- The messages you send to a character or to the book chat
- Passages from your books that a request needs (for a translation, the text you selected and the sentences around it)
- Photos you choose to send in a chat (so a character can see them)
We send only what a request needs. If you add your own AI provider in the app's developer settings, those requests go straight from your device to that provider instead.
