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.
