Homework help that points to the page

Generic chatbots invent answers. Offline AI Expert answers homework questions from your own textbooks and cites the passages it used - all on-device.

The trouble with asking a chatbot

A cloud chatbot answers from a blurry memory of the entire internet - which is how students end up quoting confident nonsense in essays. Worse, the question, the worksheet and sometimes the whole textbook travel to someone's server first, where they join a log nobody in the classroom asked for. Neither problem helps you learn - a study tool should fix both, not cause them.

Answers grounded in your textbook

Offline AI Expert takes a different path: load the PDF - a textbook chapter, the lecture notes, the assignment sheet - and ask. On-device vector search finds the passages that matter, and the answer comes back with citations pointing to exactly where they were found. Your material is the source, not the internet's guesswork. And because the file never leaves the phone, neither do your questions about it.

Built for studying, not copying

Because every answer points back to a page in your own material, the app behaves like a decent tutor: it shows you where to read instead of handing over something to paste. 'Which section explains this?' is a homework question too - and it is the one that actually helps when the exam arrives. The goal is finding things faster, not thinking less.

Works where homework happens

Everything runs on the phone - no upload, no account, no network. Kitchen table, school bus, the library corner with overloaded Wi-Fi: the textbook and the assistant travel together. Load the PDF once at home and the help is available wherever the homework actually gets done - which is rarely next to the router. Even a group study session works: pass the phone around and everyone asks the same book.
