Products

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.

Sayo

Talk. Sayo handles the rest.

A voice-first note-taking app that turns spoken thoughts into structured tasks, calendar events, and reminders. Record a memo, and Sayo extracts what matters using on-device Apple Intelligence. No cloud, no API keys, no typing.

0Daily

Daily puzzles. Zero ads.

Four puzzles, one daily ritual: Sudoku, Letters, a 5x5 mini crossword, and Blocks, a 3D roll-the-block game. Streaks, stats, Game Center leaderboards, and iCloud sync across devices. Built because every free puzzle 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.
