One job, done right
Each tool solves one core problem and solves it deeply. Not a Swiss army knife, but a scalpel.

Tools that respect
your workflow.
We build focused utilities for Mac, Windows, and the web.
Each one solves a real problem with no bloat and no compromise.
How we build
Great tools should follow clear principles

Native first
Built on native APIs with zero drivers. We respect system design instead of fighting it.

Privacy by design
Local-first architecture keeps your data on-device. No tracking. No telemetry.
04
No subscriptions for basics
Core functionality is sold as a one-time purchase. No lock-in and no forced subscriptions.
