Founder and maker of Mentalium, a voice CBT diary with on-device AI transcription. I built it after my own years in CBT therapy for anxiety and depression: the diary is what makes CBT work, but keeping one by hand between sessions never did — it always got reconstructed from memory two hours before the appointment. Voice plus offline AI was the fix. I write and publish on mental health tech, on-device AI, and building a privacy-first product as a solo founder. https://speakerdeck.com/trubetskov 2026-06-01 04:36:06 -0400 Mentalium is a voice CBT diary with on-device AI transcription, built for therapy that fits real life.
