Show HN: I made an AI that turn live lecture into structured notes,mind-maps,PDF

Hi HN, University lectures are long, dense, and fast-paced. Like many students, I used to record them thinking I’d revisit them later — but that never really worked. Even transcripts felt like raw logs. So I built [Notorium]( https://www.notorium.app ) — an AI assistant that records live lectures and automatically turns them into structured notes, flowcharts, and mind maps— within minutes after class. What it does: - Record lectures inside the app (in-person, live) - Transcribe using Whisper - Send the full transcript to LLM - Use a custom system prompt to: - Summarize the lecture - Break it into topics - Generate visual aids: flowcharts and mind maps Extras: - Download notes as clean PDFs - Tap Simplify to make notes more digestible - Tap Expand to deepen explanations - Tag notes by subject (e.g., Physics, CS) for filtering and fast retrieval Built for - In-person learners - Visual learners (flowcharts, concept trees, diagrams) - Students who want control — skim when you&#x2
