What is HeartDialog?
HeartDialog is a subscription mental wellness chatbot that blends CBT-based prompt workflows with voice and text conversation, daily emotion tracking and a privacy-first data stance. Individuals pay 10 USD per month after a 7 day trial, with enterprise tiers for integration and custom workflows.
HeartDialog is a mental wellness chatbot that pairs large language models with a structured prompt library drawn from cognitive behavioral therapy (CBT), DBT, mindfulness and goal-setting approaches. The premise behind it is personal: the team describes building the product after discovering that professional accomplishment did not resolve persistent anxiety, and that inner calm mattered more. Conversations happen in text or voice, around the clock, and are aimed at people who want somewhere to think out loud at 3 AM without waking a friend. What separates it from a general purpose chatbot is the scaffolding. HeartDialog runs more than 170 dynamic prompts that shift according to the stage of a conversation, and it uses a keyword-optimized long context technique (the company holds patents on both prompt adjustment and context handling) so the model retains relevant threads across a session. The stated therapeutic mix is supportive counseling plus CBT, mindfulness and goal-setting exercises, developed with practicing counselors. A daily emotion summary logs and analyzes mood over time, and enterprise customers get a backend with real-time usage reporting and configurable synchronous or asynchronous alerts. Privacy gets unusual emphasis. The company says data is handled under GDPR and HIPAA compliance, transmission and storage use an encrypted protocol, login is private, no personal information beyond the required account is collected, and third-party model providers are not authorized to use the data. The homepage also states plainly that HeartDialog is supplemental support and does not replace professional care. It fits between journaling apps and on-demand therapy: more structured than a generic assistant, lighter and cheaper than a human counselor. Individuals pay 10 USD per month, new accounts get a 7 day trial, college students are offered four years free, and businesses can license it per monthly active user or commission a custom deployment. Native iOS and Android apps are listed as coming soon.
How do you use HeartDialog?
1Create a private account
Open the login page and register. HeartDialog states that beyond the required login it does not collect personal information, so keep the credentials separate from identifying details if anonymity matters to you.2Choose voice or text for the first session
Both interaction modes are included in the personal plan. Pick whichever feels less exposing, and start with a single topic rather than a full history.3Set a goal so the prompts can adapt
The dynamic prompt system adjusts to your conversational stage. Naming what you want from the session, such as calming anxiety before sleep or reframing a recurring thought, gives the workflow something to work with.4Review the daily emotion summary
After conversations, check the emotion summary and analysis. Treat the log as a pattern finder across days rather than a verdict on any single entry.5Read the CBT background to get more from sessions
The blog explains how cognitive behavioral therapy reframes negative thought patterns. Understanding the model makes the AI's reframing questions easier to answer honestly.
6Understand the limits and the paid terms
The premium overview covers what the subscription includes and where the product draws the line. HeartDialog does not replace professional care, so keep a clinician in the loop for anything clinical.
