Yes. Text Prefix/Suffix 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 Prefix/Suffix upload your text to a server?
No. Text Prefix/Suffix 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.

What happens to your text when I close the tab?
It is discarded. Text Prefix/Suffix keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
