Klean Data

Ask, don't write SQL

It removes the gap between a question and an answer: no hand-written SQL, no guessing at schemas, just a conversation with your data.

Every query is transparent. Klean Data shows the exact statement it intends to run and the plan behind it, so nothing touches your database without a human saying yes.

Transparent by design

Connectors make it work across engines, and the AI adapts its queries to each schema it discovers, explaining results as clearly as it explains the query.

Any database, any schema

The React and TypeScript front end keeps the chat fast and readable, while a FastAPI backend handles connections, query generation, and safe execution.

Model routing through OpenRouter means the right model handles each task, balancing speed and quality without locking you to one provider.

Human in the loop

Human-in-the-loop approval is the core safety principle, the AI proposes, you decide, and only approved queries ever run against real data.

Klean Data is built for real teams: connect a production replica, ask in plain English, and get answers you can trust, with the query always in view.

Built for real teams

Klean Data is built around trust and control. Connect PostgreSQL, MongoDB, MySQL or a CSV, ask in plain English, and the AI writes the query, shows its plan, and only runs it after you approve, so you always see exactly what will touch your data.

Each component is built to be modular and reusable, making it simple to maintain consistency while evolving the design.

Safe by default

Klean Data is not just about making a strong first impression, it’s about sustaining it. As brands grow and their needs expand, the template continues to support new ideas, content, and directions without losing its identity.

Answers you can trust

Every element in Klean Data works together to create a clear, confident presence. It gives brands the tools to express themselves boldly while staying grounded in structure, resulting in a digital experience that feels both powerful and refined.
