Privacy-first tools
Your input. Your browser. Nothing else.
Most online tools work the same way: you paste something in, it gets sent to a server, and you hope nobody looks at it or keeps a copy. Noviilo is built the other way around — whenever a tool can run entirely in your browser, that's the only place your input ever goes.

Not: your input sent to a server, held in a database somewhere, and a result sent back. For the tools below, that second path simply isn't how the code works — there's no upload step to intercept, because there's no upload step.
