Build powerful forms, surveys and quizzes with AI in minutes
Describe the form you need in plain language and Zite generates a branded form with logic, file uploads, and payments.
Add conditional logic, intelligent routing, and multi-step workflows to automate what happens after each response.
Respondents can log in to update their answers, and forms can be restricted to internal users only.
Use custom themes, fonts, logos, custom CSS, your own domain, and embed forms as popups, sliders, or full-screen pages.
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.
