Feel
Real clicks, not buzzes
Every click is a real one under your thumb, not a vibration faking it. Choose how many there are and where they sit along the slide.
An EDC fidget slider that doubles as a Programmable Instrument.
Real clicks you can reprogram, and a sound for every one. Tell Pi, our AI, what you want to feel and hear, and it tunes both.

What we're building toward. The working prototype is in progress.

Feel
Every click is a real one under your thumb, not a vibration faking it. Choose how many there are and where they sit along the slide.

Sound
Seven clicks, seven notes, each with a tap of vibration to match. Metal, raindrops, wood, strings. Swap them whenever you like.

Digital
Save your favorite setups and switch in a second. Record a riff and play it back. Share a feel with a friend.
Try it here
Drag the slider, or tap the track.
Your screen can only play the sound. The real one clicks back.
AI
The AI in the echopi app. Describe a feel or a sound in your own words, and it builds both for you.
“Like an old mechanical keyboard.”
PiAll seven clicks on, each with a clean metal tick.
“Three clicks, room to glide.”
PiJust three clicks, with long, quiet glides between them.
“Rain on a tin roof.”
PiEvery other click on, each one a raindrop note.
“A heartbeat you can hold.”
PiClicks in pairs with low, warm notes, like a pulse.
Works for tunes too. Hum a few notes and Pi maps them onto the seven clicks.

Specs
Two layers of brushed metal and a single light, built to be picked up a hundred times a day.
