Shibutani Software Lab

Building productivity software.

Our approach

Local-first

Your data lives on your device. We build software that works fully offline and keeps you in control.

Privacy-aware

No tracking, no analytics, no surveillance. External data transmission only happens when you explicitly choose it.

Focused workflows

Each product does one thing well. Minimal interfaces that stay out of your way.
