About this tool
Paste sample text to run the fixed pattern \b\w{4,}\b with the global flag. The output lists each matching word and its character position.
This is a fixed-pattern demonstration, not a general regular-expression editor. There are no pattern, flag, highlighting or capture-group controls. Matching uses JavaScript word characters rather than language-aware word segmentation.
Frequently asked questions
Can I enter a custom regular expression?
No. This version only runs the displayed fixed pattern for words of four or more word characters.
