Vocabulary Builder

Kids type meanings in their own words. AI knows if they get it.

Vocabulary Builder replaces multiple-choice flashcards with active recall — students explain each word in their own language and the AI judges genuine understanding. Already in use across London selective schools and inside Microsoft Teams; teachers see live dashboards, students see streaks and badges.

What it does

Built around the moments that actually matter

Active recall, not picking

Type the meaning; AI evaluates real understanding, not pattern matching.

Tricky Words loop

Anything misunderstood comes back automatically until it sticks.

In-Teams + live dashboard

Embedded as a Microsoft Teams tab; teachers see classroom progress in real time.
