Frequently Asked Questions
Yes. Enable the 'Use Regex' option to use regular expression patterns in your search. This allows powerful pattern matching like wildcards, character classes, quantifiers, and capture groups. If your regex has an error, the tool displays a clear error message.
Yes. Use 'Replace This' to replace the currently highlighted match without affecting others. Use Prev/Next to navigate between matches. This gives you full control over which occurrences to replace.
Yes. Toggle the 'Case Sensitive' option to make your search match the exact casing of your query. When disabled, the search ignores case differences, matching both 'Apple' and 'apple'.
No. Everything runs in your browser. Your text is never sent to any server, making the tool completely private and secure for sensitive content.
The 'Whole Word' option ensures that your search term only matches complete words, not parts of longer words. For example, searching for 'cat' with Whole Word enabled will match 'cat' but not 'caterpillar' or 'copycat'.
