常见问题
Quick answers.
›Does it support regex?
Yes — toggle 'use regex' to enable JavaScript regex syntax in the find pattern. Use $1, $2, etc. for capture-group backreferences.
›Is it case-sensitive?
Toggle as needed. Default depends on whether 'use regex' is on.
›Can I do whole-word matching?
Yes — enable 'whole word' to match only complete words (uses regex \b internally).
›Is my text uploaded?
No — runs entirely in your browser.
›Is the tool free?
Yes — fully free, no signup.
