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 database built on object storage for agent memory and context
Graph, WAL, value, and index data all live in S3-compatible storage with a hot/warm/cold tiering strategy, cutting infrastructure cost dramatically versus memory-resident graph databases.
One query can traverse graph relationships and run vector, BM25, and reranked search together, so agents do not have to orchestrate four separate systems.
Every change is tracked, letting agents recall what happened, when, and in what sequence, which supports auditability and long-running agent workflows.
OpenCypher over Bolt plus an HTTP API and SDKs make it approachable for teams already familiar with property graphs.
