Frequently asked questions

Is Text Similarity Checker free to use?

Yes. Text Similarity Checker is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.

Does Text Similarity Checker upload your text to a server?

No. Text Similarity Checker processes your text inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.

Is there a limit on how much input I can use?

Text Similarity Checker handles inputs into the megabytes without trouble; the only real limit is how much your browser tab can hold in memory.

Do I need to install anything to use Text Similarity Checker?

No installation is needed. Text Similarity Checker runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.

Can I use Text Similarity Checker on a phone or tablet?

Yes. The Text Similarity Checker interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.

What happens to your text when I close the tab?

It is discarded. Text Similarity Checker keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
