Jammy: Building a Human-Centered Emotional OS Through Music

Jammy, a voice-first wellness app that uses emotionally attuned music to support users in real time, is creating 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 freely like they would to a trusted friend, and receive playlists, prompts, or support tailored to how they actually feel.

Hume’s EVI plays a critical role in this experience, enabling Jammy to analyze vocal cues such as tone, intensity, and nuance. This emotional signal powers Jammy’s real-time content recommendations, making each interaction feel personally relevant and emotionally attuned.

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, Powered by Hume

Jammy integrated Hume’s EVI to bring emotional awareness to its conversational AI layer. This allowed the platform to respond to how a user sounds, not just what they say, removing the need for manual mood check-ins and unlocking natural, supportive conversations.

• Emotionally Aligned Music: EVI analyzes the emotional tone of a user’s voice and delivers music that mirrors or gently shifts their mood.

• Empathic Reflection Prompts: Based on vocal cues, Jammy offers reflection prompts that respond to underlying emotions even when unspoken.

• Validating Nudges: 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.
