Rishi turns the books on your devices into conversations. Read your EPUB and PDF library on iPhone, iPad, and Mac, then ask questions, get summaries, or talk through a passage out loud β€” all without leaving the page. Bring your own books. Drop EPUB or PDF files into Rishi and they live in a fast, searchable library with covers, progress, and a Reading Now shelf. Highlights and notes follow you across devices. Read the way you like. A focused, customizable reader handles fixed-layout and reflowable EPUBs, scanned PDFs with a real text layer, and table-of-contents jumps. Pick light, dark, or sepia. Adjust font size and spacing. Search every page. Pick up where you left off. Open a book on your Mac, keep reading on iPhone on the train, finish on iPad in bed β€” Rishi syncs your position, highlights, and notes in the background using silent push. Chat with any book. Ask "what does this chapter argue?" or "summarize this scene," and Rishi answers grounded in the book you're reading. Conversations are saved per-book and per-session, so you can come back to the thread later. Talk it through.
