Independent Studio · Stuttgart, Germany
Games and AI software,
made in Stuttgart.
Crimson Dragon is a one-person indie studio. We're bringing the 1989 classic Oil Imperium back as Oil & Soil, and building AI tools like Change Happens and rytica. Since 2011.
What we're building
Our Products
Oil & Soil
Our remake of the 1989 tycoon game Oil Imperium. Build an oil company, trade on the world market and outplay your rivals.
Change Happens
Tell Change Happens which websites to watch and what matters to you. Its AI agents check the pages and let you know when something relevant changes.
rytica
Mindmapping with AI. Type a topic, get a first draft of the map, then change it however you like. Works offline and syncs between Windows, Mac, Linux, iOS, Android and the web.
GKV Alarm
Get notified when your German statutory health insurer raises its additional contribution. The overview of all insurers is free; push alerts come with a one-time Pro purchase, no subscription.
Piano For Kids
Our first app, and families still play it today. Kids learn simple songs by tapping the highlighted animals on colored piano keys and singing along.
