Objective results, not impressions
A score per unit, a level test and a measure per skill (vocabulary, grammar, pronunciation, comprehension). Adaptive instruction improves final grades with a large effect size (d = 0.85) compared with non-adaptive instruction.
Weekly dashboard and early alerts
Who logs in, how much they study, what score they get and who is falling behind. Systems with early alerts raise completion from 62% to 88% and cut inactivity by 40%.
Retention that lasts
Short units and scheduled review: 74.6% recall after 28 days compared with 53.9% for a conventional digital course.
Fewer hours for the same level
Conversational practice with AI completes learning up to 4 times faster, and the system does not repeat what the person has already mastered.
A cost that does not grow with queries
The AI teacher serves the whole workforce at once, at any hour, with no hourly cost or timetable. You pay per person and per level.
A pilot to check it
30 days, one group, a weekly report. If you see no progress, you stop it.
