Planchette: A Ouija Board Driven by Gemma's Real Token Probabilities

A developer built Planchette, a Ouija-style web app in which the planchette moves according to the actual next-letter probabilities of Gemma, a language model running locally on a laptop. When the model is uncertain, the pointer visibly swings between candidate letters before settling on one. Users can choose among three spirits, each with its own personality, and the app includes features such as live odds display and spirit responses that aren't pre-scripted. The project was submitted to the Hacktoberfest Open-Source AI Challenge and is available on GitHub, requiring Ollama and Python with no additional dependencies.
