Most Markdown editors mean installing a heavy desktop app, fiddling with IDE extensions, or paying for a subscription. For people who live in the browser anyway, launching another resource hog just to take notes is wasteful, it clutters the desktop, drains battery, and adds friction.
live.md cuts through that. Keep it open in a browser tab instead. A new tab uses far fewer resources than an Electron app or IDE, and your workspace stays clean.
