Riddle transforms reMarkable into interactive Tom Riddle diary

Riddle is an open-source application built in Rust and C for the reMarkable Paper Pro that recreates the magical experience of Tom Riddle's diary from Harry Potter. Users write on the e-ink display, and after a pause, the app captures the handwriting, sends it as an image to a Vision LLM, and animates the AI's response writing itself out in a flowing cursive font before fading away.

// ANALYSIS

–This is a remarkably creative hardware hack that seamlessly blends modern generative AI with nostalgia to create a deeply immersive "magical" experience.
–The technical execution is impressive, particularly the decision to bypass the native OS UI and write a custom interposition shim for the e-ink engine to achieve the lowest possible pen-to-glass latency.
–It demonstrates a compelling diegetic interface for AI, proving that we can move beyond standard chat bubbles and keyboards into interfaces that feel physical and magical.
–Relying on Vision LLMs to read the user's raw handwriting from a committed page image is a smart, robust alternative to standard OCR, allowing the LLM to interpret context and intent alongside the text.

CHOI builds LLM Wiki workflow system

AI creator CHOI built an operational workflow system centered around Andrej Karpathy's 'LLM Wiki' pattern to capture employee responsibilities and company context in structured markdown. The system automatically decomposes commands into specialized agent tasks, prompting the creator to declare humans as the primary organizational bottleneck.
