AI search and retrieval platform for modern apps and commerce
Deliver keyword, semantic, and hybrid results from a single index, with natural-language query understanding built in.
Create, test, and deploy AI agents, and generate grounded conversational answers via retrieval-augmented generation over your own content.
Use behavioral signals to surface related products and tailor results to each visitor's journey.
Curate category pages, pin or boost items, and track performance in dashboards without engineering support.
Graph, vector and text retrieval for AI agents on your Postgres
Query graph, vector, full-text and hybrid retrieval through one consistent interface instead of stitching multiple systems together.
The open-source pgGraph engine follows relationships across your records, enabling multi-hop and shortest-path retrieval without moving data.
Semantic search over embeddings combines with sparse and full-text matching so queries that mix meaning and exact terms still work.
A dashboard playground, CLI for imports and configuration, and a typed Python SDK make it straightforward to prototype and then ship.
