Unique: Uses multi-dimensional performance signals (accuracy, response latency, error type) to trigger curriculum branching rather than single-metric thresholds, enabling finer-grained adaptation than platforms that only track completion or accuracy alone

vs others: More responsive than Duolingo's fixed-level progression because it adjusts within sessions rather than only between lessons, and more granular than Babbel's instructor-driven pacing
