How Word Counter works

Word Counter runs entirely in your browser. Words, characters, sentences, reading time and keyword density. Under the hood it uses Plain TypeScript (small, dependency-free code that runs instantly in your tab). Your files are read into this tab’s memory, processed on your own CPU, and handed back to you as a download. Nothing is sent to a server.

Tips
