The AI reader that helps busy people actually finish more books
Ask for a plain-language explanation of dense or confusing passages without leaving the book you are reading.
Bring your own library — ebooks, PDF documents and web articles are all supported formats.
Instant translations, pronunciations and definitions in more than 118 languages turn real books into study material.
The app learns when you are most likely to read and prompts you at that time instead of on a fixed schedule.

AI research platform for reading, understanding and writing scientific papers
Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
