Someone turned a reMarkable Paper Pro into Tom Riddle’s diary, with disappearing ink

If you’ve ever wanted to own the magical diary from Harry Potter and the Chamber of Secrets, a new open source project now makes it possible. A developer has created a mod for the Pro Remarkable Paper that transforms the electronic ink tablet in an AI-powered version of Tom Riddle’s haunted diary.

Maxime Rivest designed the experience to make you feel like writing in a real notebook instead of chatting with an AI. He writes a message on the page with the pencil and then pauses. After a moment, your writing slowly fades away as if the tablet is absorbing the ink. The page “thinks” for a second before an answer appears in elegant cursive, written across the page stroke by stroke. After a while, that response fades as well.

The developer says the goal is to completely eliminate the usual AI interface. There are no keyboards, chat bubbles, or glowing screens. Instead, users interact with the AI ​​by typing on the tablet.

Behind the scenes, the project takes a snapshot of the handwritten page, sends it to a large vision-enabled language model, and transmits the response to the tablet. It works with OpenAI-compatible APIs, including OpenAI, OpenRouter, and Groq, as well as compatible local servers that support image input.

According to the developer GitHub pageAnswers start appearing on the E-Ink screen in about a second, and the handwriting animation begins before the AI ​​has finished generating the full answer.

That said, installing the project is nothing magical. It is only compatible with reMarkable Paper Pro, requires developer mode, SSH access, and third-party startup software, and makes deep system changes by temporarily taking over the tablet’s interface. The developer also warns that it runs with root privileges, has been tested only on specific software versions, and may stop working with future updates.
