Turn vocabulary into memory—not just a one-time score.
Paste terms, definitions and optional example sentences. The lab creates adaptive and spaced rounds, recycles weak words, checks confidence calibration, diagnoses mistake types, and builds an active-recall-weighted mastery estimate you can export and continue studying.
