About Jammy
Jammy is a voice-first wellness app that creates an emotional operating system designed to help users feel seen, heard, and supported without the friction of traditional wellness tools. The platform combines conversational AI with emotionally aligned music recommendations, allowing users to speak naturally and receive playlists, prompts, or support tailored to how they actually feel.
Hume's Empathic Voice Interface (EVI) plays a critical role in this experience, enabling Jammy to analyze vocal cues such as tone, intensity, and nuance.
The Challenge: Making Emotional Support Feel Effortless
Jammy set out to solve a common but overlooked challenge: people want to feel better, but often don’t have the energy or language to explain what they’re feeling or what might help. Existing mood-tracking apps typically ask users to self-report or select from static menus, adding friction at the exact moment users need support the most.
The team needed a solution that could detect emotion in real time without relying on users to articulate how they felt.
The Solution: Real-Time Empathic AI with EVI
Real-Time Emotional Intelligence: Hume's EVI enables Jammy to respond to vocal tone, not just words, removing manual mood check-ins and enabling natural conversation.
Emotionally Aligned Music: EVI analyzes emotional tone and delivers music that mirrors or gently shifts the user's mood based on emotional cues.
Empathic Reflection & Validation: Users expressing sadness, stress, or frustration receive gentle nudges that help them explore or acknowledge how they feel.
For example, if a user says “I’m fine” but their tone reflects frustration or sadness, Jammy might recommend a playlist that speaks to those deeper feelings, followed by a prompt to reflect on what’s beneath the surface.
Results
Since integrating Hume's EVI, Jammy has achieved remarkable growth and user satisfaction:
- 109% increase in monthly active users (MAUs)

Jammy's User Feedback:
I use Jammy when I'm looking for the perfect playlist for the specific moment I'm going through. I don't have to search or think too hard—it just gets me.
When I’m overwhelmed, I don’t want to explain what I need. I just talk to Jammy. Somehow it gets the tone of my voice and plays exactly the right thing. It’s like a friend who knows what I need before I do.

Hume's EVI has enabled Jammy to move from surface-level personalization to true emotional resonance, building an emotionally intelligent product that listens, understands, and supports people when they need it most.
