Jalees: AI Study Companion

Jalees turns the material you are already studying into something you can ask questions of. Upload a textbook, a lecture recording, or your own notes. Jalees reads them, and then answers questions grounded in the exact page or transcript timestamp in front of you — not a vague summary, and not something it invented. WHAT YOU CAN DO Read your own books Open a real PDF with crisp text at any zoom, or switch to a clean text view. Highlight, annotate, and pick up where you left off on any device. Ask about the page you are on The assistant sees what you see — current page, current scroll, current zoom — and answers about exactly that. Every answer points back to the page it came from, so you can check it. Turn a lecture into something searchable Upload a lecture video or audio recording and Jalees transcribes it. Ask a question and the answer is tied to the moment in the recording it came from. Work through a topic step by step Guided study builds a lesson from your own material and walks you through it, with narration if you want to listen instead of read. See it, not just read it When a diagram would explain something better than a paragraph, Jalees builds a small interactive visualisation inline. Adjust it, and ask follow-up questions about it. Keep the rest of your studying in one place Notes and notebooks, a units-aware calculator, and a calendar that syncs your timetable so deadlines sit beside the material they belong to. Study in your language Full support for English, Dutch, and Arabic, including right-to-left layout. BUILT FOR REAL COURSEWORK Jalees was built by a graduate student for their own degree, and it is shaped by that: dense technical PDFs, equations, diagrams, lecture recordings, and the specific problem of finding the one paragraph that explains the thing you are stuck on.
