What can your voice tell you?

We tell ourselves stories in order to live.
— Joan Didion

Kintsugi is a smart voice journaling platform for mental health. We use voice biomarkers to measure and predict well-being.


Kintsugi measures your mood and well-being with your voice. Convenient and discreet, Kintsugi is available on smartphones and home devices and pairs well with earbuds at home, work, or in the car.


With increasing awareness of improving our physical health through wearables, we actively measure steps as a proxy for fitness. Stress, anxiety, and depression are pervasive across modern society costing American employers $500B annually in lost productivity, yet how can we make reasonable strides in mental health if we don’t measure it?


Kintsugi has developed a neural-network model specifically for journaling entries that can analyze raw text and audio from natural conversation to discover speech patterns indicative of depression. Beyond recognizing sentiment, people love learning about how their voice biomarkers are tied to sleep, nutrition, outdoor activities, and other physiological triggers and adjusting personal habits to track positive outcomes.

We support the highest level of encryption (256-bit AES, E2EE) and are HIPAA compliant for use with your primary care person. We take privacy seriously and will never share individually-identifiable information. Our priority is in your personal well-being and we thank you for purchasing a Kintsugi license or subscription and entrusting us as your advocate.

Your Journey

Isn’t it incredible that no one’s journey is exactly alike and even with the same set of circumstances, outcomes can vary wildly?

You are remarkable in every way, and your experiences shape your values, attitudes, and beliefs. How we perceive and understand the world around us can dramatically shape our well-being and even impact our future success.

Wouldn’t it be amazing to improve your well-being by taking unhelpful thoughts and modifying the thinking around that?


What is Expressive Journaling?

Expressive writing, a free-flowing expression not impinged by typical grammatical or punctuation editing, demonstrated through Pennebaker Paradigm and in 200 successful U.S. clinical trials in reducing stress, anxiety, and depression, has demonstrably shown improvements for people immediately following the practice and beyond 2 months.

Further, expression from voice annotated journaling entries and more frequent entries as a result of lower friction of use, provides a continuous feedback loop, much tighter than the current episodic physician or psychiatrist check-in.

Utilizing cognitive behavioral techniques and tight coupling with features from Apple Health Kit, a user from a few voice journaling entries from the Kintsugi application, can start to track physiological activities with sentiment analysis and emotion classifiers from the latest advancements in Natural Language Processing. Deep reinforcement learning is also being applied on a points system from the recommended actions and activities based on mood (e.g. meditation for anxiety, walking for anger, etc.) and provides an incredibly customized, mental wellness solution for individuals.

What is CBT?

Cognitive behavioral therapy helps you become aware of inaccurate or negative thinking so you can view challenging situations more clearly and respond to them in a more effective way. CBT can be an effective tool to help anyone learn how to better manage stressful life situations.

CBT includes learning and practicing techniques such as relaxation, coping, resilience, stress management and assertiveness.

Kintsugi will encourage you to talk about your thoughts and feelings and what's troubling you. Don't worry if you find it hard to open up about your feelings. Your confidence and comfort grows with openness.

CBT generally focuses on specific problems, using a goal-oriented approach. As you work through your process, you may be asked to do exercises that build on what you learn from your sessions and we encourage you to apply what you’re learning in your daily life.

CBT follows these steps:

Identify troubling situations or conditions in your life. These may include such issues as a medical condition, divorce, grief, anger or symptoms of a mental health challenge.

Become aware of your thoughts, emotions and beliefs about these problems. Once you've identified the problems to work on, Kintsugi will encourage you to share your thoughts about them. This may include observing what you tell yourself about an experience (self-talk), your interpretation of the meaning of a situation, and your beliefs about yourself, other people and events.

Identify negative or inaccurate thinking. To help you recognize patterns of thinking and behavior that may be contributing to your problem, Kintsugi may ask you to pay attention to your physical, emotional and behavioral responses in different situations.

Reshape negative or inaccurate thinking. Kintsugi will encourage you to ask yourself whether your view of a situation is based on fact or on an inaccurate perception of what's going on. This step can be difficult. You may have long-standing ways of thinking about your life and yourself. With practice, helpful thinking and behavior patterns will become a habit and won't take as much effort.

Convenience and Health+

Kintsugi voice journaling is convenient, smart, and helpful in building a fuller picture of your health and well-being. Discover more about what makes you tick and reinforce positive behaviors for future success.

Always consult your primary care if you have an urgent issue and need live support. Kintsugi is not a substitute for seeing a therapist. We highly encourage strong relationships with your primary care provider and can also recommend qualified therapists near you. Our mission is to provide access to measuring our well-being and tools to promote positive holistic health. The Kintsugi community is here to support you and your journey.


As I get older, I want every tool and advantage to help me cope with my challenges. I know that avoidance isn’t a long-term solution.
