Upload your PDFs and start reading.


A focused reading mode shows only a few lines at a time, helping you stay immersed and absorb the text more deeply.
Every page you finish adds context—highlights, lookups, and threads with the author chat. Our AI keeps that thread, so suggestions and answers improve the more you invest in the book.


Find ideas, themes, and concepts across in your PDFs.
Context-aware prompts and reflections appear as you read. The AI uses memory from your progress and past sessions, so the longer you stay with a text, the more tailored and useful the nudges become.


Tap any word to see definitions, examples, and synonyms—right where you are—so you never lose momentum while reading.
Customize font size, spacing, and line length to suit your eyes and your focus—designed to support long, comfortable reading sessions.


Your notes come together as a visual map, helping you spot patterns, connections, and insights across everything you read.
