AI-moderated customer interviews that turn conversations into decisions
Describe your objective and the platform drafts objectives, likely questions and probing context, or you can upload your own interview guide.
Studies are filled from a qualified global network covering many markets and languages, with targeting to match your audience.
Responses are turned into ranked preferences, insight quotes and theme summaries, so readouts are ready without manual coding.
Beyond words, the platform captures hesitation, emotional tone and gaps between what people say and what they do.
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.
