Mentalium Launches Voice CBT Diary with Offline AI Transcription on the App Store

```
FOR IMMEDIATE RELEASE

Yerevan, Armenia - May 27, 2026 - Mentalium, a new mental health app developed
by solo founder Pavel Trubetskov, is now available on the App Store. The app
lets users keep a cognitive behavioral therapy (CBT) thought diary entirely by
voice, with AI transcription running locally on the device.

CBT is one of the most evidence-based forms of psychotherapy, recommended by
NICE, APA, and WHO for anxiety, depression, OCD, and panic disorder. Its
effectiveness depends on keeping a structured thought diary between therapy
sessions. In practice, most people skip this - typing during a moment of anxiety
or a panic attack is not feasible.

Mentalium removes that barrier. Users press a record button and speak through
the five steps of a CBT thought record: situation, automatic thought, emotion,
reaction, and alternative thought. The AI on the phone transcribes the recording
and fills each field automatically. No typing is required at any point.

The transcription model runs entirely on the device. After a one-time download
of approximately 180 MB, the app works fully offline - on the subway, on a
plane, or anywhere else. Diary entries stay in a local database on the phone.
No voice data is sent to any server.

Additional features include anxiety rating (1-10 scale) before and after each
entry, charts tracking progress over time, cognitive distortion analysis across
seven languages, and an encrypted Excel report that users can email to their
therapist before sessions.

Mentalium supports English, Russian, Spanish, French, Portuguese (Brazilian),
German, and Italian. A free 7-day trial is available, followed by a subscription
of $4.99 per week or $29.99 per year.

"I built this after my own years in CBT therapy," said Pavel Trubetskov, founder
of Mentalium. "The gap between knowing the diary works and actually keeping one
in the moment - that's what the app closes. Voice was the obvious answer.
On-device AI was the missing piece."

Mentalium is available now on iPhone. An Android version is in development.
