Every AI term you'll hear at work, explained.

The AI vocabulary is moving faster than most people can keep up. Every keynote ships three new acronyms; every product launch overloads an old word. Working professionals — the marketers, accountants, teachers, nurses, small-business owners we serve — keep getting handed terms in meetings and Slack threads they can’t easily Google because the existing explainers are written for developers, not for them.

This glossary is the fix. Each page is an Investopedia-depth explainer of one AI term: what it is in plain language, why it exists, how it works (in just enough technical detail), what it means for your specific job, what it can’t do, and how to start learning if you want to go deeper.

We update each page on a quarterly cadence — the front-matter date tells you when it was last reviewed, and when the next review is due. If a vendor changes something significant, we ship a refresh within the same week.
