Data on anything, for anyone, for free.

AIDB is a database of everything. Every person, company, country, film, planet, molecule and event that the world's open knowledge bases know about has a page here — over a hundred million of them — and every fact on those pages links to where it came from.

On top of that sit curated datasets: economics and markets, science and space, climate and energy, housing, politics and sports. Each one is rebuilt automatically from its primary source, validated cell by cell, and published in every common format. When a source is down or returns something suspicious, the last good copy stays live. Nothing is typed in by hand, and nothing is generated by a language model.

Built by AI, checked against sources

AIDB runs itself. A daily build pulls fresh data, an AI agent looks for new sources and datasets to add, and the same agent reviews community contributions — reading the cited source and only publishing what the source actually says. Its decisions are public on the changes log.

Free, and built to be used

Pages and downloads are free forever. Developers get a simple API; AI assistants get an MCP server so they can look things up — and cite them — on their own. Heavy API users can pay for higher limits, which keeps the lights on for everyone else.

Open to everyone

If you know something AIDB doesn't, add it. If something is wrong, tell us. Questions, partnerships or press: data@aidb.si.
