Supermemory VS Readlink

Readlink's answer:

Readlink is the all-in-one book app. Instead of one app to track, another to read, another for notes and a group chat to talk about it, Readlink does all of it: book search and barcode scan, one-tap page tracking, a PDF reader with highlights and notes, reading stats and streaks, author pages, and a social feed where every post is tied to a real book. It also compares your library with other readers and with curated libraries of founders, writers and thinkers, and shows exactly which books you share.

Readlink's answer:

Most book apps do one job. Goodreads and StoryGraph track, e-readers read, note apps hold highlights, and the conversation happens somewhere else. Readlink keeps the whole reading life in one place, so your progress, notes and discussions stay attached to the book. Recommendations come from the books you actually finished, not just what you added. Moving is easy: import your Goodreads shelves from a profile link or CSV. The core app is free, and Premium adds AI reading chats across your own books and notes, plus shelf scanning that adds a whole bookshelf from one photo.

Readlink's answer:

Curious readers who read to learn, mainly non-fiction: founders, builders, researchers, students and anyone whose reading shapes how they work and think. They want a clean record of what they read, a place to keep the ideas that stayed with them, and other serious readers to talk to. Fiction readers are welcome too, and can shelve anything.

Readlink's answer:

Readlink is developed by Lykan Sagl in Switzerland together with Quanteron in the USA, and launched on iOS and Android in June 2026. The mission is to change how readers organize, manage and share their personal libraries and the knowledge in them. Since launch it has grown from a library and social feed into a full book app, adding a reading tracker and stats, a PDF reader, author pages, weekly picks, AI reading chats and AI shelf scanning.
