It started at Lost Village.
I was in the middle of a set I never wanted to end. The song, the lights, the crowd, the feeling. I wanted to keep all of it. What I had was a dark, shaky clip on my phone, and no record of the song that made the moment.
By Monday, that clip had vanished into my camera roll, somewhere between screenshots and photos of lunch. The moment was still in my head. On my phone, it was just another file.
The problem is universal
Talk to anyone about their phone and they'll tell you the same story. The set they filmed but can't find the track to. The festival weekend that's a folder of dark clips by Monday. The night out that meant everything and lives nowhere. The moments that matter most are the ones hardest to find, because our phones are designed for capture, not meaning.
Your camera roll is chronological. Your brain is emotional. That's the gap.
Music is the bridge
Neuroscience has known this for decades. A song triggers what researchers call 'music-evoked autobiographical memories': vivid, specific, emotionally intense recall of a particular moment. Dr. Petr Janata at UC Davis found that 30% of popular songs cue vivid personal memories. Not vague nostalgia. Concrete moments with people, places, and feelings.
When the right song comes on, I'm not 'remembering Lost Village.' I'm back in that exact spot: the sound, the light, the people next to me. That's what I wanted a phone to be able to keep.
So we built Chord
Chord is where the clip, the song, the feeling, and the reason it mattered live together. Film the moment and Chord names the song from your clip. If it can't, add it in two taps. Write a line if you want. No typing in the crowd. Then find any night by song, artist or place, or just say "Hey Siri, show me Lost Village on Chord."
We didn't build another journal, or another photo or video app. We built an app for live music, where the moment and the song stay together, built for the nights your camera roll was never made to hold.
Naming the feeling
Pixar gave us core memories. Scandinavians gave us hygge. Portuguese gave us saudade. But the feeling of a song dropping you back into a specific moment of your life: that didn't have a name. So we gave it one.
A chord memory is a specific moment in your life (a person, a place, a feeling) permanently bookmarked by a song, and brought back the next time you hear it. A set at Lost Village isn't 'a video on my phone'. It's a chord memory. And there are hundreds more, scattered across your music library, waiting to be claimed.
That's the feeling Chord is built around.
Capture the night. Relive it forever.
That's Chord. Chord is in open beta on iPhone right now. Android is coming.
