Ask a little.
A question, a half-formed idea, something you’re curious about. Hold the paddle and talk it through with Muse.
“Can you explain that more simply?”
A little device for your Muse
Your Muse.
A little more
tangible.
Meet Yolk. A lightweight e-ink companion that puts Muse in your hand. Ask out loud. Hear back. Let the words settle on paper.
Prototype in progress. A small thing with a lot ahead of it.
Push to talkPaper-like e-inkPowered by MuseA little personality
Small device. Meet big possibility.
It’s your Muse.
With something to hold.
Yolk gives Muse a home beyond your phone: a microphone, a speaker, a quiet screen, and a button you can find by feel. What you do with it comes from Muse—and the tools you connect to it.
Get your bearings.
Bring the useful bits into view. A briefing, a reminder, a list—through the capabilities available in your Muse setup.
“Give me a quick morning briefing.”
Make things happen.
Reach the tools and compatible devices you’ve connected to Muse. A little button can be the start of something useful.
“Turn on the desk light.”
Illustrative requests. Available actions depend on your Muse account, connected tools and compatible hardware. Yolk connects over Wi-Fi. Explore Muse Gadgets ↗
The very short instructions
Hold. Talk.
And there’s Muse.
One physical paddle starts the conversation. A little ink companion lets you know what’s happening.
- 01
Hold to talk.
Press and hold the side paddle. Say what’s on your mind, in your own words.
- 02
Let Muse take it from here.
Release to send. Yolk shows a thinking state while Muse works on your request.
- 03
Hear it. Read it.
Replies can be spoken through the speaker and shown on e-ink. A small screen for the words that matter.
A screen with a softer side
A little ink.
A little less glow.
Black and white. Paper-like. Easy to glance at. Yolk’s e-ink screen reflects the light around it instead of shining back at you.
It holds an image without powering the display continuously. A reply, a status, a familiar little face—right there on your desk.

Small screen.
Big character.
Listening looks like listening. Thinking looks like thinking. And when something goes wrong, Yolk says so.
The character brings a little warmth to the wait, with expressions drawn for the monochrome screen.
A little look under the shell
Small outside.
Quite a lot inside.
Every layer has a job. The e-ink display, board, speaker and battery fit inside a two-tone printed shell, held together by four rear screws.
This is the actual enclosure CAD. Turn it around, take it apart, and see how it all fits.
- 01 Printed shell & screen surround
- 02 E-ink display & ESP32-S3 board
- 03 Speaker & rechargeable battery
- 04 Rear tray & four screws
Current prototype CAD, including the planned dial.

A little room for you
Make it
yours.
Warm yellow? Quiet sage? Something a little brighter? Mix a body colour with an accent and give Yolk your own feel.
Drag the device to turn it around. The back, dial and screen surround share the accent finish.
Finish studies, not product options. The dial is the remaining prototype addition, planned for reply scrolling and quick settings such as volume.

A few things you might be wondering
Good questions.
What can I do with Yolk?
Talk to Muse through a dedicated device. Ask questions, work through ideas, or use the tools and services connected to your Muse account. Yolk provides the voice controls, speaker and e-ink display; Muse provides the assistance. Specific actions depend on your setup.
Does it work offline?
The current experience needs Wi-Fi and a connected Muse account to send requests and receive replies. E-ink can retain an image without a connection, but that doesn’t mean Muse runs offline on Yolk.
What does the dial do?
The dial is the remaining addition to the prototype. It is planned for scrolling multi-page text replies and controlling quick settings such as volume. It is shown in the design mockups and CAD model.
Can I buy one yet?
Not yet. Yolk is a prototype, with no confirmed price or shipping date. You can get in touch to follow its development and hear about future opportunities to try it.
Is this a Muse product?
Yolk is an independent device project built using the open-source Muse Gadgets SDK. Muse powers the connected experience. Learn about Muse Gadgets ↗
