Tools we built for everyone.

We don't just build software for clients. We build products that solve our own problems first, then ship them to the world.

Sudoku

Sudoku. No ads. Ever.

An ad-free, distraction-free Sudoku built in SwiftUI with SwiftData persistence. Daily puzzles, multiple difficulties, and clean haptic feedback. Built because every free Sudoku app on the App Store is buried under banner ads and interstitials.

MAGI

A council of agents that argue.

Three local Ollama models (Melchior, Balthasar, Casper) deliberate on your hard calls. They see each other's verdicts, rebut by name, and land on consensus or deadlock. Auto-journaled so you can revisit decisions later.
