What is Bookmuse?
Bookmuse is an AI language-learning tool built into a mobile reading app that lets you learn a language while reading books you already own. The core loop is read-and-translate: hold a word and tap Translate, and a card slides up with the meaning that word has in that specific sentence, so the translation is contextual rather than a dictionary stub. A Listen feature uses on-device voices for English and Vietnamese and can fall back to Apple or online providers, and an FSRS spaced-repetition system turns sentences from your own books into flashcards for vocabulary retention. An Ask AI feature answers questions about a passage or the whole book with page references, and the app exposes an MCP integration so Claude or ChatGPT can manage your library. Books import from EPUB files, Google Drive, Dropbox, or Project Gutenberg classics, sync across devices through an optional account, and can be shared with friends by link. Bookmuse is free with no ads, in-app purchases, or tracking; an account adds Bookmuse AI with a daily allowance and 300 MB of cloud storage. For readers who want language study inside the book rather than in a separate app, it is a privacy-first pick among the language tools BestAIFor tracks.
