The reMarkable is an E Ink writing tablet for reading documents and textbooks, sketching and note-taking that attempts to fully replicate paper writing. Developed by a Norwegian startup company of the same name, the device is geared towards students, academics and professionals.

The reMarkable uses electronic paper reading display and tablet computer writing system.

The company was founded by Magnus Wanberg and started product development in Oslo in early 2014. It has collaborated with Taiwanese company E Ink. Development was started in 2013 and a crowdfunding campaign launched in late 2016. Pre-orders began in 2017.

ReMarkable uses its own operating system, named Codex. Codex is based on Linux and optimized for electronic paper display technology.

As Codex is based on Linux and an open source ecosystem, it has gained community projects and 3rd party software for it. The device is accessible through SSH, allowing the installation of 3rd party software. Many packages are accessible through Toltec, a community-maintained free software repository. The Cloud system has been reverse engineered and an open source alternative has been created.

An alternative free operating system, Parabola-rM, has been made to replace Codex. Parabola-rM aims to turn the device into a full-fledged computer, allowing typical desktop Linux applications to be run, with the caveat that this is not a supported configuration.

In October 2021, a connect plan was launched which required a monthly subscription for its Connect Lite plan or its full Connect plan with unlimited cloud storage. This was withdrawn in September 2022. Some of the original features that were withdrawn, such as integration with file hosting services, were made available to all ReMarkable owners, with a single Connect plan price with a reduced price.

Of the first generation of the tablet, Remarkable 1 (or ReMarkable RM100 as known by its model number), launched in late 2017, suffered some criticism due to sluggishness when loading and unloading files.
