Mentalium is a voice-powered CBT diary with built-in AI transcription. Developed together with professor of psychotherapy Alexander Erichev, it is built to make your cognitive behavioral therapy genuinely more effective.The real progress in CBT happens between sessions — when you keep your thought diary regularly. That is the key "homework" of therapy: the more often you work through your automatic thoughts, the faster your thinking shifts and your anxiety eases. The problem is that almost no one keeps the diary by hand — typing on a phone is slow, and a notebook is never around. So people fill it in from memory a couple of hours before their session. That works about as well as going to the gym once a month.Mentalium removes the main obstacle. Anxiety does not arrive on schedule, and you need to capture the thought in the moment — while it is still fresh. Just tap record and say it out loud: the AI instantly turns your speech into a structured CBT entry. The act of speaking and reframing the thought already helps you get through a wave of anxiety more calmly.How it worksThe app guides you through every step of the CBT thought diary:— Rate your anxiety level before the entry— Describe the situation that triggered anxiety— Identify the automatic thought— Name the emotion and physical reaction— Formulate a more realistic, calmer thought— Rate your anxiety level after the entryNo typing — just talk. In the car, at home, on a walk.Watch your anxiety go downMentalium records your mood and anxiety level before and after each entry and shows the dynamics: how many entries you have made, how your anxiety changes over time, and which cognitive distortions come up most often. Progress is visible — and that keeps you from quitting.Why CBTCognitive behavioral therapy is one of the most researched, evidence-based approaches to anxiety. Its core tool is the thought record, or thought journal: catch the automatic thought that set off the anxiety and replace it with a more realistic one. Mentalium makes that tool convenient enough to actually use every day.Share with your psychotherapistSend your CBT diary entries to your psychotherapist straight from the app in one tap. The app builds an Excel report for the selected period and emails it.
