On October 21, 2026, Kopek Japan announced the launch of a project to develop a collaborative keyboard with Keychron and illustrator and designer lack.
The project page introduces it as a “left-hand device” for illustration and other creative work.
The project is currently in development, and a survey is underway to gather user feedback on key layout, usability, and the software they would like to use.
The survey is open through November 15, 2026.

A Project Inspired by lack’s “Ideal Left-Hand Device”

According to the project page, the project began with an idea for an ideal left-hand tool that lack posted on X on January 28, 2026.
Keychron responded to the post’s call for manufacturers to get involved, leading to a joint development project.
lack is an illustrator whose work includes character illustrations for Fate/Grand Order and Touken Ranbu -ONLINE-, as well as designs for VTubers including Shiranui Flare.
The project aims to create a device for a wide range of users, including illustrators, designers, gamers, and video editors.

Seeking Feedback on Key Layout, Usability, and Preferred Software
The survey asks for feedback on key layout and usability, as well as the software and apps users would like to use the device with.
The goal is to understand how people will use it and develop a product suited to their needs.
| Item | Details |
|---|---|
| Project | Keychron × lack Collaborative Left-Hand Device |
| Current status | In development |
| Survey period | October 21–November 15, 2026 |
| Feedback requested | Key layout, usability, and preferred software and apps |
| Who can respond | Anyone interested in keyboards, including fans of Keychron and lack |
| How to respond | Access the survey from the project page |
For those dissatisfied with their current left-hand device or looking to streamline the controls they use most during creative work, this could be an opportunity to share their needs.
Pricing, Release Timing, and Full Specifications to Come
The product’s official name, price, release timing, connection method, and final key layout have not been announced yet.
The project page also has an email sign-up form for updates on development progress and release information.
Beyond the key layout, it will be interesting to see how controls such as dials and customization features are designed.
Summary
That covers the device being jointly developed by Keychron and lack.
Keychron seems to have been exploring new possibilities for keyboards in recent years, actively engaging with users on its official social media and proposing product ideas.
This initiative also seems to be an extension of that approach to development.
The user survey is open through November 15. If you have specific ideas about the key layout or usability you want from a left-hand device, why not share them while the project is still in development?
