Why STACK Exists
Modern note SaaS apps have become bloated database engines pretending to support Markdown. STACK restores Markdown as the first-class citizen.
Typing Never Waits
Every stroke commits to memory and IndexedDB immediately. Network sync happens in the background. Even during a complete network blackout, your editor flows uninterrupted.
Pure Markdown Storage
No obfuscated binary formats or proprietary database schema. If you export your workspace, you get clean, standard Markdown files readable on any system forever.
Post-War Industrial Tooling
A restrained palette of worn steel, slate, and bone white with red-slate controls. Built to feel like heavy-duty military avionics, not a childish toy or noisy gaming UI.
MARKDOWN WITHOUT THE NOISE
No proprietary blocks.
No hidden document format.
No database-shaped writing.
Just Markdown, with a workspace built around it.
