Hit Listen. Relai captures the whole lecture in real time, so you follow along instead of scribbling.
One hotkey. Relai reads the live transcript, works out what you're asking, and answers it: direct answer first, then the detail.
One click turns a lecture into a clean PDF: summary, key terms, and practice questions from what was actually said.
Small touches that make it usable in a real class.
Capture a diagram, slide, or problem set and Relai explains it, for when the hard part is visual rather than spoken.
Tell Relai what you're studying, whether it's organic chemistry or statistics, and every answer matches that subject's depth and terms.
Collapse Relai into a thin floating bar that stays out of your way, wherever you're working. Audio is processed live and discarded; nothing is stored unless you save it.
No card to try it. The free plan is genuinely usable.
Available for Windows today. macOS is on the way.
Transcribe the lecture, get answers on the spot, and leave with a study sheet. Free to start.
