What it does
ActuallyFreeTools compares two versions of any text for free and highlights every addition in green and deletion in red — by word, line or character. Ignore capitalisation and extra spaces when they do not matter. It is handy for contract clauses, essays, code and lists, and the text never leaves your browser.
How to use it
- Paste the original and the changed text.
- Choose by word, line or character.
- Compare and read the highlights.
Questions people ask
Can I compare two PDFs instead?
Yes — Compare PDFs reads both files and shows word changes plus a visual overlay.
Is my text sent anywhere?
No. The comparison runs in your browser.
Which mode should I use?
Words for prose, lines for code and lists, characters for short strings like IDs.
Is Text compare on ActuallyFreeTools really free?
Yes. There is no sign-up, no daily limit, no watermark and no paid tier. Nothing is held back for paying users.
Are my files uploaded anywhere?
No. Text compare runs inside your browser, so your files are processed on your own device and never sent to a server. That is also why there is nothing to meter or charge for.
