About Folirei

Folirei is a Japanese (and English) language-learning ebook reader with built-in spaced repetition. Import epub, txt, or manga, read with instant word lookup, mine vocabulary from the exact sentence you met it in, and review it with FSRS scheduling.

The whole learning loop is free, forever: importing, reading, lookup, furigana, pitch accent, mining, and review. Bring your own AI key (Ollama, OpenAI, Anthropic, and others) at no cost, or upgrade for managed, no-setup AI and cloud sync across every device.

Folirei runs natively on desktop and mobile, with the same library and progress syncing everywhere you read.
