Record a lecture, get notes — how it works

AI lecture notes are class notes made from a recording. You record the lecture, and hearlog transcribes it with Google Gemini, then writes structured notes and key points — so you can listen and understand in class instead of racing to copy the board.

Handwritten notes force a trade-off: pay attention, or write things down. In a fast statistics class or a dense UPSC lecture, that trade-off costs you the explanation of why a result matters. Recording removes it. hearlog writes out what was said, then hands you a transcript you can search, a detailed summary for deep study and a key-points list for the night before an exam.

With a free account, every lecture is saved, so a semester becomes one library you can search. Looking for the professor's definition of "opportunity cost"? Search your notes — or, on Pro, ask "What did sir say about opportunity cost, and in which class?" across all of them. Nothing to install, and recording keeps going even if the campus Wi-Fi drops.

hearlog is built by USD Vision AI LLP and powered by Google Gemini AI. See the full workflow for students on our students use-case page.
