About

The AI Dictionary explains artificial intelligence terms in plain English, for students, teams, and anyone curious.

Every definition is checked against at least one trusted source, such as ISO/IEC 22989, the NIST AI glossary, the Google Machine Learning Glossary, or the paper that introduced the term. Sources are listed on every page.

Every definition is written and checked by people. Pages marked Draft haven't been reviewed yet. If you can't find a term, search for it and choose Request. The most-requested terms are written first.

Privacy: to learn which terms to add, we count the words people search for. We store only the search text and the date, never who searched. No cookies are used, and searches aren't counted if your browser sends a Global Privacy Control signal.

Developers can use the free JSON API: /v1/terms.json for the list, and /v1/terms/<slug>.json for one term.
