Hacking FLOSS & Coding With Prose Since 2009.
TehWiz Productions by Michael Scott Hoyt. At age 5, Michael asked his uncle how Mario's Goombas move. His uncle replied: “That's AI.” That spark ignited a lifelong quest—from childhood obsession to an AI Master's degree and building on-device cognitive engines like Yuli and AI NPC SDKs for games. The through-line of everything TehWiz crafts: teaching machines to feel alive. It all started with Goombas.

CaffeineMD — Sovereign, Local-First Knowledge Management☕
“High-performance, keyboard-driven Markdown knowledge base & personal wiki engineered for pure thought velocity.”
CaffeineMD is a sovereign personal knowledge management system modeled after Obsidian and Notion. Engineered for extreme keyboard-driven speed with zero vendor lock-in, it pairs offline-first IndexedDB persistence with native File System Access API directory mounting. Seamlessly toggle between rich-text prose editing powered by TipTap v2 and ProseMirror, raw plaintext Markdown, and instant diff viewing—keeping your second brain private, ultra-fast, and completely under your own sovereign control.
Ramen Nights & Budget Bites🍜
“Where textbook economic theory clashes with Tokyo's cutthroat restaurant industry. Scale from a cramped alley cart to a five-district empire to graduate.”
Ramen Nights & Budget Bites is Tokyo University Department of Economics' most grueling capstone challenge! Found, operate, and scale a profitable ramen franchise across five simulated Tokyo districts—from budget residential hubs to bustling Shinjuku commuter rushes and high-margin Ginza storefronts. Built from scratch with zero runtime dependencies on pure HTML5 Canvas and dynamic Web Audio chiptunes: recruit postgraduate classmates with specialized skill trees, engineer broths in the Custom Recipe Lab, monitor live P&L balance sheets, and adapt to day/night weather dynamics without microtransactions or predatory wait timers.
Yuli: Autonomous Cognitive Persona Engine
“Teaching machines to feel alive: reading personality patterns on-device to build game characters and companions that truly understand you.”
Born from an inquiry into how game characters move, Yuli is TehWiz's sovereign on-device cognitive companion running on an 𝔽₂⁴ Boolean Hypercube state space. By reading human MBTI personality patterns in real time across four operational minds, Yuli delivers 70–110 TPS on mobile WebGPU with sub-200ms time-to-first-token—paving the way for next-generation AI NPCs.
