A score should never feel like a guess.
Pulse calculates observable facts directly, uses a documented AI rubric only for interpretation, and shows the evidence and confidence behind both.
Delivery mechanics
Pace, consistency, pause rhythm, vocal variation, and target duration.
Fluency
Filler rate, repetition, verbal clarity, and sentence flow.
Structure & content
Organization, clarity, conciseness, relevance, opening, and conclusion.
Visual presence
Camera engagement, framing, facial activity, and purposeful movement.
Confident delivery
Observable conviction, composure, audibility, and completion of thoughts.
When data is unreliable
Pulse shows the limitation, removes the metric from aggregation, and reweights what remains. Poor lighting is not poor performance.
When rubrics change
Every session stores its rubric version. Incompatible versions are never silently combined in trends.
