Show HN: Resona – Finds connections across what you save

Built Resona (https://useresona.com) to solve a recurring frustration: you save something, think "this relates to something I read before" — and never find what.

Those connections are where the aha moments live. Same underlying idea, different domain, months apart.

What it does: - Save anything (Chrome extension or forward emails) — no folders, no organizing - Weekly digest surfaces connections across months of reading - Interactive graph ("Overtones") shows how ideas relate over time - Chat with your library — "What have I saved about scaling teams?"

Tech: TypeScript monorepo, React SPA, Supabase (Postgres + Auth), OpenAI for embeddings and semantic search, Chrome extension.

Would love feedback: Do the surfaced connections make you want to revisit what you saved?
