About the project

Quill is an E-ink UI framework we created to drive E-ink displays on low-cost hardware. Inspired by React for the web and SwiftUI for iOS, Quill enables developers to build sophisticated apps for various IoT devices, including restaurant menus, medical devices, and digital price tags. Because it’s tailor-made for low-cost embedded devices, it can drive stunning displays without any advanced—and expensive!—hardware.

The Calming Effect of E-Ink

The key advantage of E-Ink is that it provides a calmer experience compared to regular screens, as the display doesn't emit light but resembles paper or a sign.

The Benefits of E-ink

What sets Quill apart is its departure from simply copying traditional LCD-centric digital design and instead playing to the strengths of e-ink technology. By leveraging e-ink's unique aesthetic, Quill creates interfaces that feel tangible and authentic, transforming digital interactions into tactile experiences. This unique approach not only ensures optimal performance but also enhances the user experience by delivering interfaces that feel both real and intuitive.

Tailored for Developers

We put a lot of effort into making Quill developer-friendly, enabling faster development cycles and better end results. Developers will recognise the paradigms and best practices from mobile and web development and feel right at home.

What’s more, Quill removes the need for embedded development, enabling anybody to build beautiful UIs.

Words from the team

❝ E-ink is awesome; it looks great and is easy on the eyes. But until now, it’s been challenging to develop beautiful and snappy user interfaces for E-ink devices. Quill aims to change that.
