What's New in Lectr 4.0 Book Recommendations Get personalised book recommendations based on your reading portrait. Your tags and themes are mapped to generic literary descriptors on-device before anything is sent. The server never sees your personal vocabulary. Thematic Search Search your notes and quotes by concept, not just keywords. Type "power" to find passages about authority, control, and influence (even if those exact words never appear). Powered by on-device NLEmbedding; nothing leaves your device. Book & Quote Sharing Share books and quotes via universal links. Recipients can add shared books to their library with one tap, with automatic duplicate detection. ISBN Scanner Improvements Three-tier metadata lookup (ISBNdb → Open Library) for better coverage of obscure and non-English titles. Now includes a flashlight toggle for low-light scanning.
