ENGINEERED FOR SERIOUS WORK

Built like physical stationery.
Powered by native code.

Modern cloud boards suffer from memory bloat, sluggish zoom, and arbitrary subscription walls. Parchment is built from first principles for instant flow.

01 / LOCAL-FIRST

Your Files in Documents

No proprietary cloud database lock-in. Every board is stored directly on your drive as clear JSON in ~/Documents/Parchment. Sync automatically with Git, Syncthing, or OneDrive.

ZERO CLOUD SILOS
02 / DEEP ZOOM

0.3% Deep Superzoom

Miro locks up at 2.5%. Parchment zooms out 8x further down to 0.3%, allowing you to inspect massive multi-year architectures and enterprise roadmaps at high altitude with zero stutter.

8X WIDER VISUAL RANGE
