Hey HN — I built this after realizing I kept forgetting everything people told me. My friends would mention their job stress or a family situation, and two weeks later I'd ask as if they'd never said it. Aura lets you describe an interaction by voice, the AI extracts the key details and sets a reminder, and there's a social coach for when you need to prepare a difficult conversation. Stack: Netlify Functions, Groq (llama-3.3-70b), Supabase. Fully PWA — installs like a native app on iOS and Android. Would genuinely love feedback on what's missing.
