Mentalium is a voice CBT diary with on-device AI transcription, built for therapy that actually happens in real life.
THE PROBLEM
Cognitive behavioral therapy works when you keep a thought diary between sessions. But typing in the moment of anxiety, panic, or a post-work meltdown is impossible. Most people end up filling it two hours before therapy, from memory — and CBT loses half its effect.
HOW MENTALIUM WORKS
Press the red record button. Speak the five steps of a CBT thought record — situation, automatic thought, emotion, reaction, alternative. The AI on your phone transcribes everything and places it in the right field of the diary. No typing, no cloud, your voice never leaves the device.
PRIVACY BY DESIGN
The transcription model runs entirely on the phone, downloaded once (~180 MB), then offline forever. Every entry stays in a local database. No cloud sync. No analytics on what you said. No model training on your worst night.
PROGRESS YOU CAN SEE
Rate anxiety on a 1–10 scale before and after each entry. Charts show how the curve moves week by week. Cognitive-distortion analysis highlights patterns from your text — catastrophizing, mind-reading, all-or-nothing — across all seven supported languages.
FOR YOUR THERAPIST
An Excel report for any period (7, 30, 90 days, or all-time) goes to your therapist's email in one tap. Encrypted with AES-256, structured by the five CBT steps. Sessions start prepared, not scrambling to recall the week.
