Relai runs on your desktop, transcribes every word from your lecture or meeting live, and answers your questions instantly with AI — so you can focus on learning, not note-taking.
No credit card required · 60 free minutes per month
Relai sits on top of every window, captures audio in real time, and gives you AI-powered answers without switching tabs.
Every word appears as it's spoken. Works with your microphone for in-person lectures or system audio for Zoom, Teams, and recorded content.
Press one hotkey and Relai reads the transcript, finds the question being asked, and gives you a clear answer. No copy-pasting into ChatGPT.
Capture your screen or select a region and Relai will analyze it with AI. Works with diagrams, code, slides, or anything visible on your display.
Load your lecture slides, textbook PDFs, or notes. Relai pulls relevant passages automatically when answering, grounding responses in your course material.
Shrink Relai to a thin floating bar that stays out of the way. Still shows live transcript snippets and lets you ask AI with one click. Expand any time.
Save any session as a polished PDF with the full transcript, AI-generated summary, highlighted key concepts, and your complete Q&A history.
Audio is processed and discarded in real time. Nothing is stored or sent anywhere except what you explicitly save. All API calls are server-side.
Tell Relai what you're studying and it generates a tailored AI persona. Get answers tuned to organic chemistry, constitutional law, or whatever you need.
Relai adapts to how and where you work.
