Voice CBT diary with offline AI
Your private voice-powered CBT diary. Speak, track anxiety, and share reports—completely offline.
Overview
Mentalium is a revolutionary CBT thought diary that you keep by voice instead of typing. When anxiety strikes—in the car, in a queue, or mid-panic—you simply answer five CBT questions out loud. An AI model running directly on your phone transcribes your answers and fills in the diary instantly. One entry takes just 1–2 minutes, compared to 15 minutes with traditional methods.
Your privacy is paramount: nothing leaves your device. Your voice recordings and notes stay fully private and offline. The app provides before/after anxiety scales and visual charts to track your progress over time. A one-tap report gives your therapist a clear picture of your real week, making therapy more effective.
