Tools

Small, single-purpose things I built for myself. They run in your browser rather than on a server, so nothing you put into them is sent anywhere.

Single-page tools

One page each, nothing else. No account, no sign-in, and nothing you type ever leaves your device.

Workbench

Bigger, and less strict about it. Still no account and nothing uploaded — but this one loads a couple of libraries from this site, and can read and write files in a folder you choose.

Everything stays on your device

Nothing here has a backend, and nothing is uploaded, stored or tracked. Whatever you type is kept in your own browser's local storage, so clearing your browser data clears the tools too, and opening one on another device won't carry your notes across.

The single-page tools go further: each is one file that makes no other requests at all, and works with the network off. The markdown editor loads its parser and a stylesheet from this site, and can read and write files in a folder you pick — that happens directly on your device, and it only ever sees the folder you chose.
