glossary.dev learn everything anywhere

The AI tutor that meets you where you are.

It builds on what you already know, quizzes you until it sticks, and won't skip the foundations underneath. Whether you're seven or a CTO.

Open app What it does
What it does

Four things, every session.

Teaches

Walks you through it at your level, draws a picture when one helps, and points you to the best things to read or watch.

Tests

You say it back in your own words. It judges the reasoning, not the recall, and names the gap.

Builds foundations

Won't go deep while the ground under it is shaky. Shores up the missing piece first.

Remembers

Tracks your confidence on every term. Each session picks up where the last one left off.

Who it's for

Same tutor. Every stage of learning.

One engine. It meets a seven-year-old and a CTO each where they are.

Selective-test prep, or whatever they wonder about.

Times tables and spelling one day; dinosaurs, the planets, or Harry Potter the next. Big buttons, talk to it out loud, and a picture when it helps.
