How this works

Every tool runs entirely in your browser. There's no server behind this. No database, no accounts, no analytics tracking what you paste. Your text goes into a JavaScript function on your machine and the result shows up on your screen. That's the whole architecture.

We built this because most online tools want your email before they'll format your JSON. Or they're "free" but your data takes a round trip through someone else's infrastructure. Scratchpad skips all of that. The code runs client-side. You can verify it yourself (View Source still works, we checked).

Works offline too, once the page loads. Airplane mode, sketchy hotel wifi, that one conference room where nothing connects. The tools don't care. They already have everything they need.
