Special characters like `\n` (newline) or `\t` (tab) in the pattern box will be interpreted literally.
Select any desired flags (e.g., Ignore Case, Multiline).
Click "Test Regex". Matches will be highlighted in the "Results" box below the input.
Match details, including captured groups, will appear below the controls if matches are found.
