wordcounter.net
Counts words and characters, and shows which words you overuse.
Live word, character, sentence and paragraph counts with reading and speaking time, plus a keyword-density panel that quietly reveals you have written 'basically' eleven times. There is a goal setting for anyone writing to a fixed count, and it keeps working while you type rather than needing a button. It is a counter with some analysis, not an editor.
AltFTool does this too
If you would rather not leave the site, Word & Character Counter covers the same job here — free, no account, and it runs in your browser.

Works the moment the page loads. No account, no email, no trial. Ad-heavy, and the grammar and AI extras bolted onto it are far weaker than dedicated checkers.
No. WordCounter does the work inside your browser, so the file never leaves your device — you can load the page, disconnect from the network, and it still works. That makes it a reasonable choice for material containing personal data.
