About whatisai

whatisai explains AI terms in plain words. Each explainer takes about five minutes to read, has one diagram, and shows where every fact came from.

Where to start

Start here lays out what to learn, step by step, at beginner or deeper level, and the daily lesson gives you one five-minute explainer a day. The glossary covers 890 terms. AI news is a short daily edition, updated at 7 PM ET: new models, open-source releases, research and what developers are trending, each in one plain line linked to the original source.

How it is written

Every factual sentence is backed by an exact quote from a primary or official source, and each explainer is checked for originality. Drafts are not published. Read how we write.

What it costs

Nothing. The site is free and open source. There is no sign-in, no accounts, no paid tier and no ads. Deep dives are public too.
