Small, sharp software.

How we build

Three things we don't compromise on.

Local-first

Software that keeps working without a server. Your data lives with you — in your Drive, on your disk, in your browser.

Minimal by default

No bloat, no dark patterns. Each tool does one thing and does it fast.

Cross-platform

One idea, every surface — desktop, Android, web, browser extensions. Build once, run where people are.
