Lingvist
Adaptive vocabulary built on spaced repetition
We publish a full Four-Mismatches fit assessment for the student-facing exam tools first. For this one, the facts below are what we have verified — run the Four Mismatches Test on it yourself for your own students.
Independence: Addestra builds learning products too (MathsTutor, TinkerWell). We never review or score our own, and no tool pays to be listed or to rank higher — how we assess fit.
What it does
What the AI actually does — An adaptive algorithm models each learner's knowledge and schedules vocabulary via statistical spaced repetition tuned to usage frequency.
Why it was built — Use data science to learn a language faster by focusing each learner on exactly the words and gaps they need next.
