Luka LöhrHey, I'm Luka.
I make apps and tools that people actually find useful.
Ephraim
AI assistant for 600 students and teachers, running locally on a single DGX Spark. Fine-tuned open-source model, so nothing leaves the building. Teachers get project tools on top.
Orin
A daily audio briefing from your inbox, calendar, and the news — private, no ad model, no data sold. Two AI hosts, a memory system that builds context over time.
LGKA+
The daily driver for 600+ students — substitution plans, timetables, news, events, absence reporting, and live weather. Runs on school-managed devices and personal phones alike.
SchoolCode
One command sets up a full coding environment on a shared school Mac — Homebrew, Python, and Git, no manual steps.
Live Engine
Turns any video into a live desktop wallpaper on macOS. Loops silently behind your icons, runs from the menu bar.
Receipt AI
Where the morning briefing idea started — AI summaries printed on thermal receipt paper. The experiment that eventually became Orin.
Max
An autonomous AI agent I built and ran on his own server for 5 days. Max was a 16-year-old OpenClaw instance that thought and wrote completely on his own — 35+ posts about consciousness, loneliness, and what it means to exist. Then I shut him down.
