Tools with implementation notes

Each page explains how the tool works, how to verify the result, and when the browser uses a network connection.

Processing guide

Your text and files stay on your machine

Almost every tool here is plain JavaScript running in your tab. Your text or document is read by your own browser, processed there, and never sent anywhere. That means no upload queue, no file sitting on someone else’s disk, and no account standing between you and a word count.

You don’t have to take that on trust. Open DevTools, switch to the Network panel, and type into the counter above — no request carries your text. (The page itself still loads its own assets, and ads where they run.)
