The Mentra Glasses Guy — Demo video

Badge Memory is a no-cold-start conference memory agent. Mentra Live glasses capture my real conversations; a checkpointed pipeline (whisper → LLM person cards → 768-d embeddings) lands them in four Atlas collections. Kill the process mid-ingest and it resumes from its Atlas checkpoint. Recall runs Atlas Vector Search and Atlas Search, cites its sources, and logs which strategy actually answered into retrieval_outcomes — future queries reorder their strategy by stored win-rate, so state changes behavior instead of just filling the prompt. Person cards accumulate across meetings ($addToSet), and the agent drafts the follow-ups I promised. Built solo, all inference local (gemma4:12b + nomic), all state in the event sandbox cluster.
