AI Jargonaut

Every term now tells you where you'd actually meet it — the products and tasks it turns up in. Plus a new FAQ in Settings.

The language of artificial intelligence, explained on your device.

AI Jargonaut turns AI jargon into something you can say out loud without bluffing. Start from a curated set of 48 acronyms and terms — each with its full expansion, a plain-language definition, an everyday analogy to make it stick, where you'd actually meet it, the source it came from, and the date it first appeared — then make the whole dictionary your own.

WHERE EVERY TERM IS ACTUALLY USED

New in this version: every entry now names the products, systems, and tasks the term turns up in. Not more theory — RAG comes with enterprise Q&A over internal documents and citation-backed chat; Quantization with 4-bit local inference and integer-only edge deployment. It's the line that turns "I've read the definition" into "I'd recognise one."

DEFINITIONS WRITTEN ON YOUR DEVICE

Type an acronym on the Ask screen and Apple Intelligence fills in the full term, the definition, the analogy, the uses, the source, and when it first appeared. On devices with Apple Intelligence it runs entirely offline.

PRIVATE BY DESIGN

What you look up stays with you. There's no account to create, no server to ask, and nothing reported back to anyone.

ON EVERY DEVICE YOU OWN

Terms you add travel through your own iCloud account, so the same entries are waiting on your iPhone, iPad, Mac, and Apple Vision Pro.

WRITTEN BY YOU, NOT JUST FOR YOU

Rewrite any entry in your own words and illustrate it with your own picture. Change your mind and Restore Original puts back the definition, analogy, uses, source, date, and illustration the term came with. Take the lot with you as a plain JSON file, and bring it back the same way.

A TERM AWAY, WHEREVER YOU ARE

Search your acronyms and terms from Spotlight, ask Siri to define one, or keep one on your Home Screen with the widget.

QUESTIONS, ANSWERED

A new Frequently Asked Questions page in Settings covers how to edit a field, what editing costs you, how to put the original back, what happens to a bad date in an imported file, and why some entries are dated January 1st.

The app now speaks Spanish throughout. The dictionary entries themselves are in English.

Definitions are drafted with a language model and offered as a starting point, not as authority. Please read the Disclaimer before you begin.
