An EDC fidget slider that doubles as a Programmable Instrument.

Describe the feel.
Pi makes it real.

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.

Concept render

Feel it. Hear it. Make it yours.

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

Brushed metal curving over woven fabric

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.

A drop falling into dark water

Sound

Every click has a voice

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

Folded brushed metal with a thin lime line

Digital

Fully digital, totally yours

AI

Meet Pi.

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.
