Inspiration

Millions struggle with mental health, often hiding pain behind "I'm fine." According to the WHO, one person dies by suicide every 40 seconds, and depression affects over 280 million people worldwide. Most never get help.Not because it doesn't exist, but because it's hard to ask, and harder to notice.

Resonate listens to your voice, not just your words. Decades of research show that acoustic features in speech can reveal mood and emotion (Scherer, 2003). We believe technology can help us hear what’s unspoken, making support more accessible and stigma-free.

Resonate is a lifeline, not just an app.

What Resonate Does

Resonate is an AI-powered emotional wellness companion that analyzes your voice to understand your mood. It combines how you speak (acoustics) and what you say (semantics) for over 90% accuracy.

How it works:

  1. Record: Speak about your day (English or Bengali). No scripts, just your voice. POSTER
  2. Analyze: Our AI examines your vocal patterns and words, then fuses both for a mood score.
  3. Results: Instantly see your mood, detected emotions, transcript, and confidence level. POSTER
  4. Track: Entries are saved, letting you view trends and streaks over time.
  5. Insights & Actions: Get personalized AI insights and wellness suggestions, like meditation, journaling, or reaching out to a friend, based on your mood. POSTER

Resonate follows a easy-to-use liner workflow for users. Everything is private, secure, and designed to help you understand yourself better.

Why it matters: Most apps ask you to rate your mood. Resonate listens. Your voice reveals what words can’t. We help you notice patterns and get support before things get worse.

Beyond mood tracking:

  • Guided journaling
  • Gratitude practice
  • Wellness goals
  • Support network
  • Meditation, breathing, quick workouts
  • Curated music
  • Daily reminders POSTER POSTER POSTER POSTER

Privacy you control: Choose from 4 privacy levels, from full analysis to acoustic-only. Audio is never stored. You can export or delete your data anytime. Your privacy, your choice. POSTER

Language support: English and Bengali (বাংলা) supported, with more languages coming soon.
