Features

Realistic Interview Practice

PIT simulates suspects and witnesses with distinct personalities, emotional states, and resistance levels. The AI adapts its responses based on your interview technique, creating genuinely challenging practice scenarios.

Adaptive AI Suspects

Suspects react to your approach — build rapport and they open up, pressure them and they clam up or become hostile.

Witness Interviews

Practice cognitive interviewing techniques with AI witnesses who have varying recall and emotional responses.

Voice-Enabled

Speak naturally using your microphone. PIT transcribes your questions in real-time and can respond with synthesised speech.
