MintBook AI

MintBook AI is an intelligent eBook reader that combines a seamless reading
experience with powerful AI translation — all in one app.

Read Any Format
Open and read EPUB, PDF, and TXT files with a beautiful, distraction-free
reader. Import books from the Files app, iCloud Drive, or transfer wirelessly
via Wi-Fi.

AI-Powered Translation
Select any text while reading and get instant AI translation. MintBook AI
breaks down translations into three helpful parts:
• Full sentence translation
• Difficult vocabulary with definitions
• Example sentences for context

Bring Your Own AI
Use your own OpenAI (GPT) or Anthropic (Claude) API key for translation. Your
keys are stored securely in the iOS Keychain — never on our servers.

Designed for Every Device
Optimized for both iPhone and iPad. On iPhone, translations appear in a
convenient bottom sheet. On iPad, enjoy a side-by-side panel for uninterrupted
reading.

Customize Your Reading
• Adjustable font size, family, and line spacing
• Light, Dark, and Sepia themes
• Page curl, slide, and fade page transitions
• Bookmarks and reading progress tracking

Privacy First
Your data stays on your device. The only network requests are your translation
API calls — nothing else leaves your phone.
