Wellbeing Wizard: personalized learning AI for 120K active users.

Wellbeing Wizard needed to feel like a tutor who remembers you, not a generic quiz engine. We built a personalization layer that adapts pacing, difficulty, and tone to each learner’s history, validated against real engagement metrics rather than offline accuracy alone.

Now in its third version and serving 120K active users, the system lifted engagement 38% while staying grounded in the platform’s own content — every recommendation is explainable back to the learner’s progress.

Evals and monitoring shipped from day one, so quality is watched continuously and every model update is scored before it reaches a student.
