Tools for stories, lists and lifts. And a universe.
Arctaur makes apps and games. Three are in private beta, and one is a game on its way to Steam.

01 / App for macOSAriadne
The writing tool for branching, story-heavy games.
Your story lives as plain text in your game's own repository. The app, its command line and Claude Code all work on the same files, so writer and agent never fight over a database.
- Write scenes, then play them on the spot
- Walk every path to find dead ends and lines nobody can reach
- An MCP server, so your AI can read, check and edit the story too
02 / Web app for phone and computerWhat to read, watch and play next, in an order that means something.
Oplys turns your lists into one clear next pick for each, arcs that move from gentle to intense, and a journal of what stayed with you.
- A top 20 for books, films and games, arranged into themed arcs
- Battles to settle your top 5s, and journeys across media
- The AI of your choice does the curating. There is no AI inside.
03 / Web app for phone and computerOverload
Your AI writes the plan.
Overload runs it.
Bring a plan from any AI: training, nutrition, supplements and recovery. Overload logs every set, suggests the next weight, and sends your progress back to your AI for review.
- Fast logging in the gym, and it works offline
- Weight changes are proposals. Nothing moves without your OK.
- Training, macros and supplements in one place
04 / Game for Mac and WindowsORBIS
A god game about everything that ends.
One universe, from its first instant to its last. Watch it kindle, galaxies gather, worlds cool and minds wake, in one unbroken zoom from outside the universe down to a single creature.

Get in early.
Betas are small, and invitations go out by hand. Pick what you'd like to try and we'll write when there's room.
The bear and the bull. Bjørn and Tyr.
Arctaur joins arktos, the bear, and taurus, the bull. In Danish they are Bjørn and Tyr, the two brothers this studio is named after.
