Sing into your phone. Get harmony parts for the people you love.
AI that brings real voices together. Not AI that sings for you. 🎵
Sing any song into your phone. HarmonyAlong instantly creates beautiful harmony parts — two, three, four, or five voices — for the people you love to learn and sing together.
🔒 No spam. Ever. Just one email when we launch.
Beautifully simple. Made for everyone who loves to sing.
Five simple steps. No music training required.
Tap the microphone and sing any song you love — a verse and a chorus is plenty. Don't worry about being perfect. Auto-tune gently corrects your pitch in real time as the app listens, the same way professional singers use it on stage.
Behind the scenes, the app detects your melody, identifies the underlying chords, and generates singable harmony parts based on the style and number of voices you've chosen — from a simple two-part duet to a rich five-voice arrangement.
Pick the vibe — pop, gospel, folk — and HarmonyAlong shapes the harmonies to match.
Each singer picks their part. Tap a singer to mute or unmute their voice. Slide each volume up or down. Practice your part alone first — then bring the others back in until you can hold your own against the full harmony.
When everyone knows their part, gather the people you love. Press play. Sing it together. That's the moment HarmonyAlong was built for.
You don't need to read music. You just need to love singing.
Music gives a soul to the universe, wings to the mind, flight to the imagination, and life to everything.
— Plato
"There's been a wave of AI tools that try to replace human creativity. We believe the opposite. The most beautiful sound in the world is real people singing together. HarmonyAlong uses AI as a teaching tool — so more humans, in more living rooms and kitchens and church halls, can find the joy of harmonizing with the people they love."
And as harmonies are shared from one home to another, across cities and countries, music quietly becomes what it has always been — a bridge between us. 🌍

Not at all. HarmonyAlong is built for everyday singers — from people who just love singing in the shower to those who sing in choirs. The app uses auto-tune to gently correct pitch as it listens, so don't worry about hitting every note perfectly.
Nope. HarmonyAlong is designed for people who don't read music. Each harmony part is taught the way singers naturally learn — by listening. Just press play and follow along with your voice.
We're in early development. Sign up for the waitlist and you'll be among the first to know — and the first to try it. Waitlist members will get priority access before the public launch.
There will be a free version so anyone can experience the magic of harmonizing with people they love. Premium features will be offered for those who want unlimited use, advanced controls, and additional features.
Any song you can sing — pop, gospel, folk, lullabies, hymns, holiday classics, musical theater, songs in any language. If you can hum it, HarmonyAlong can harmonize it.
Your privacy matters to us. Your voice will be used only to detect the melody — it won't be stored, sold, or used to train other AI systems. Full details on our privacy approach will be shared at launch.
HarmonyAlong is being built for both iPhone and Android, with web access coming later. Tell us which device you use when you sign up so we can prioritize your platform.
