Frequently Asked Questions
- Is my text sent to a server?
- No. All processing runs in your browser. Your text never leaves your device.
- Can I use capture groups in regex mode?
- Yes. Use standard JavaScript regex syntax — e.g. find: (\w+), replace: [$1] to wrap each word in brackets.
- Why is Whole Word greyed out in regex mode?
- In regex mode you control the full pattern, so you can add \b word boundaries yourself. Whole Word only applies in plain-text mode.
