Mentalium is a voice-powered CBT diary with built-in AI transcription.
Make entries in your CBT diary the moment automatic thoughts arise, triggering emotions and reactions.
This helps you get through an anxiety attack, panic attack, or moment of deep distress more calmly — and improves the overall effectiveness of cognitive behavioral therapy.
WHY A CBT DIARY MATTERS
Cognitive behavioral therapy is one of the most well-researched approaches to managing anxiety, depression, panic attacks, and ADHD, with proven effectiveness. Widely used by psychologists and psychotherapists around the world.
The core CBT tool is the thought and emotion journal (also known as a thought record).
It helps you track automatic thoughts that trigger anxiety, panic attacks, and depressive states — and replace them with more rational and realistic ones.
The problem is that keeping a CBT diary manually is extremely inconvenient. Typing on your phone takes too long. A laptop or notebook isn't always on hand.
You end up filling in your diary 2 hours before your session with your therapist, from memory. That's about as effective as going to the gym once a month.
Mentalium solves this problem.
VOICE-POWERED CBT DIARY
Just press record and speak. The app guides you through every step of the CBT thought diary:
— Rate your anxiety level before the entry
— Describe the situation that caused distress
— Identify the automatic thought
— Name the emotion and physical reaction
— Formulate an alternative, more realistic thought
— Rate your anxiety level after the entry
The AI built into the app instantly transcribes your speech into structured text. No typing — just talk.
Make entries in your CBT diary in the car, at home, at the office, on a walk. Anywhere. Whenever you need it.
TRACK YOUR PROGRESS
Mentalium records your mood and anxiety level before and after every CBT diary entry.
You will clearly see how regular practice with your thought journal reduces the intensity of anxiety and depression.
The app shows the dynamics of your condition — how many entries you make and how your anxiety level changes over time — and highlights your cognitive distortions.
All of this helps maintain your motivation for therapy and build confidence in yourself.
SHARE WITH YOUR THERAPIST
Send your CBT diary entries to your therapist directly from the app in one tap.
The app generates an Excel report for the selected period and emails it to your therapist.
This saves time during sessions and lets you jump straight into analyzing your thoughts.
COMPLETE PRIVACY
Therapeutic data is personal. Very. That's why all your CBT thought diary entries are stored only on your device and never transmitted anywhere.
The AI runs directly on your device. You never send voice recordings to third-party servers.
Your CBT diary is yours alone.
