The AI-powered interface for every database you run
Type a question in plain English and get an instant answer drawn from your connected data, without writing SQL by hand.
The AI editor reviews your SQL, corrects mistakes and suggests improvements, then turns result sets into presentation-ready charts automatically.
A snappy grid built from scratch for fast navigation of large tables, with customizable table plugins and edit-in-place controls.
Compose analytics boards manually or hand them to the AI, then embed charts anywhere using open-source web components.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
