Ask AI while you read
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Read PDFs on iPhone and iPad, ask AI about the current page, search the whole book, and use OCR when text is not embedded.
Yomu is a PDF reader for iPhone and iPad that helps you understand documents as you read.
You can ask AI about the pages currently open, search across the book, and read scanned PDFs with OCR support. Yomu is designed for studying, reading documents, and checking unclear parts without losing your place.
[Key Features]
• Ask AI about the page you are reading
Yomu uses the content of the currently open spread, so you can ask questions in context while reading.
• OCR support for scanned PDFs
If a PDF does not have enough embedded text, Yomu uses OCR to extract text for reading support and search.
• Full-text search across the book
Build an index for the book and jump to matching pages from search results.
• Voice input for questions
Use speech input when you want to ask without typing.
• Reading features built for documents and books
Support for two-page spreads, reading direction settings, shadow cleaning, and color inversion for comfortable reading.
Core features are free to use. A subscription is available for people who want to use AI features more extensively.
