AI SQL assistant that writes, fixes and runs queries on your real schema
Describe the result you want in plain English or another language and get SQL written with your real table and column names in the dialect of your chosen database.
Paste any query — generated or hand-written — to get a clause-by-clause explanation, corrections with reasoning, performance rewrites and clean formatting.
Execute queries against a connected read-only connection and inspect the returned rows and timing directly in the interface.
Expose your database to Claude, ChatGPT in developer mode, Cursor or your own agent through a governed MCP endpoint and a REST API with per-agent keys.
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.
