About Mentalium - CBT Diary by Voice

Mentalium is a voice-first CBT diary that lets users capture thoughts, triggers and moments of anxiety immediately by speaking into their phone. Transcription and AI processing run fully on-device (offline), so audio never leaves your phone. Designed to reduce recall bias, it helps users log authentic, in-the-moment CBT entries wherever they are — e.g., in the car, on the street, or at work.

Key Features

  • On-device AI transcription — runs offline so audio never leaves the device
  • Voice-first CBT diary for in-the-moment logging of triggers and thoughts
  • Reduces recall bias by enabling capture wherever the moment happens (car, street, work)

Who is this for?

People practicing CBT or therapy, mental-health journaling users, and privacy-conscious individuals who want immediate, voice-based recordkeeping.
