It's available on web, ios, android and has 6M+ books & audiobooks available for free. You don't even need to signup to read/listen (only necessary if you want to make notes, highlights, save progress across devices). Lex premium gets you a catalogue of exclusive translations, licensed content, and what I am calling 'lexicons' (book summaries). Also Lex AI, a conversational reading assistant (with RAG / book indexing), and a handful of other features.
Lmk what you guys think, would love to get feedback from the heavy readers out there.
