Vocabulary for your exact world.
Type any niche — 'Spanish for programmers', 'French for negotiating' — and ContextDrill generates AI dialogues and Leitner flashcards just for it.
a compromise — negotiating vocabulary
Every beginner gets the same 500 words.
Dogs, apples, umbrellas. Fine if you’re a tourist. Useless if you’re trying to review a pull request, negotiate a contract, or order dinner on a work trip. ContextDrill throws out the standard deck and writes you one for your actual life.
Type any niche, get real content.
Four example niches below — tap one to see the kind of dialogue and flashcard ContextDrill’s AI actually generates for it.
the deployment — “Antes del despliegue, revisa los logs.”
Cards move. Progress is never invisible.
Every card lives in one of five boxes. Get it right and it climbs toward “Mastered,” reviewed less and less often. Miss it, and it drops straight back to Box 1 for daily review — no hidden algorithm, just a box you can see.
This is the Leitner system, the same spaced-repetition method behind decades of flashcard learning — ContextDrill just makes the movement visible instead of burying it in a hidden score.
First review, recalled correctly — moves to Box 2.

Words saved from forgetting
Track your real progress — not just streaks, but words that actually stuck.
Every niche lives in its own deck.
Start “German for hiking trips” on Monday and “Spanish for programmers” on Tuesday — each niche gets its own card catalog entry, its own Leitner boxes, and its own progress. Nothing gets mixed into one giant pile.
Spanish for programmers
German for hiking trips
French for negotiating
Japanese for ordering food
Illustrative example — not user data
A streak tells you nothing. This does.
Most vocabulary apps show you a flame that resets to zero the moment you skip a day — which measures showing up, not learning. ContextDrill counts the thing that actually matters: words that made it all the way to Box 5 and stayed there.
Your niche text
The niche and context you type is sent to our AI processing provider solely to generate your cards, and is not used to train AI models or retained beyond your request.
Words that stuck, for niches that mattered.
I typed “Spanish for restaurant management” and got cards about inventory and shift schedules on day one. That’s not something a generic app has ever done for me.
Watching the card physically move to the next box when I get it right is oddly satisfying. It makes the spaced-repetition thing click in a way flashcard apps never have.
I have four decks going — hiking German, negotiating French, two work ones — and the category hub keeps them from turning into one giant pile.
