What is this?
I've occasionally wanted a quick and easy way to apply a simple Javascript function or algorithm on some text, but I didn't want to trust random web apps for security reasons.
I made this web app with a focus on security through simplicity. It's an app that I understand and as long as I can trust the browser and the network, I can rest assured that my data will not be leaked.
This app is intended to be easily human-auditable. If your browser supports a "Sources" tab, you can audit the code there, or you can view the source code here.
If you're feeling extra-paranoid, you can copy the source code and host it yourself. No build tools are required. This app can be hosted directly by a web server.
