Does it change my text?

No — it only reports repeats so you can edit them yourself.

Is it useful for SEO?

Yes. Density figures show when a keyword is repeated more than it should be.

Does the duplicate word finder tool work for online form and portal uploads?

Yes. It is built for portals that enforce strict file limits — exam boards, job applications, university and government forms. You control the output before you download it.

Will it work on a low-end phone or a slow mobile connection?

Yes. Files are processed inside your browser instead of being uploaded, so nothing depends on upload speed and it works on budget phones on 3G or 4G.

Is there any charge, watermark or sign-up?

No. Every tool is completely free, unlimited, watermark-free and requires no account, email or payment.
