Fable turned reMarkable into Tom Riddle's diary from Harry Potter

Points and comments are a snapshot, not live.

A developer turns a reMarkable tablet into an interactive LLM-powered diary that drinks handwritten ink and replies.

The project requires a reMarkable Paper Pro in developer mode. When the user writes and pauses, the page fades the ink, sends the image to an OpenAI-compatible vision LLM (or local pi backend), and streams a reply written in Dancing Script stroke by stroke. Two display modes: a windowed AppLoad version and a takeover mode that stops xochitl for lower latency. Gestures include flipping the marker to erase, drawing a large ? for help, and a five-finger tap to exit. The diary suspends gracefully with the power button.

What commenters are saying

Many commenters wished the README had a video embed rather than an X/Twitter link that requires an account or third-party service to view. Some found the comparison to Tom Riddle's diary (a haunted artifact that mind-controls its user) uncomfortably apt for a GenAI-powered device. A few commenters argued that calling it a "high water mark for RTFA" was unfair to users who cannot access Twitter content.
