An agentic analytics platform that turns questions into governed, trusted answers
Ask a question in plain language and get a reasoned answer with the SQL, charts and tables behind it, available in the Hex workspace, in Slack and from developer tools.
Write SQL, Python and R side by side in one project, then turn cells into interactive, parameterised data apps and dashboards without a separate BI authoring tool.
Centralise metrics, semantics and corporate definitions so answers stay consistent, and see exactly where the agent lacked grounding so you can fix it.
Run graded, rubric-based test suites against the agent to measure answer quality and catch regressions as your data and context evolve.
