Every AI search tool makes you copy data out and sync a second source of truth forever. SemiLayer flips it: an intelligence layer that bolts onto the database you already run — point at a table, declare a lens, get a typed client. Your data never leaves. Stands out: 4 features in one client (semantic search, similarity, drillable dashboards, personal feeds) where most tools do one; cross-source joins across Postgres/Mongo/ClickHouse; zero vector infra; airgap-capable Runners.
Hey Product Hunt 👋 David here — I built SemiLayer.
Every time I wanted semantic search, "more like this," or a real recommendation feed on my own data, it was the same slog: stand up a vector DB, write an embedding pipeline, babysit drift, keep a second copy of prod in sync forever. The embeddings were never the hard part. The plumbing was.
SemiLayer bolts onto the database you already run — Postgres, Mongo, SQLite, ClickHouse. Point it at a table, declare a lens in a TypeScript config, run semilayer generate:
beam.products.search("eco-friendly water bottle under $30")
Your tables stay in your DB — we query through, we don't replicate them. There's a vector index (semantic search has to land somewhere); we run it so you don't. Need airgap? A Runner in your VPC reads the rows locally and talks out over an outbound-only WebSocket — we never connect to your database directly.
Not just Pinecone with a nicer SDK: four features in one typed client (search, similarity, dashboards, feeds — other tools give you one), cross-source joins across Postgres/Mongo/ClickHouse in one call, ~100–200ms at millions of rows. Free tier is real: 10k rows, no card.
For you if you've got real users on a real database and the smart stuff — search, recommendations, a ranked feed — never made it past "someday." What SemiLayer is for (and, honestly, what it isn't): semilayer.dev/what-is-semilayer
Demo, zero signup: demo.semilayer.com. It's early — what search/rec feature did you quietly give up shipping because the pipeline wasn't worth it? Around all day.
