Flags
JavaScript flags control how the pattern runs.
Your pattern and test text are evaluated locally and never leave this browser.
Enter a pattern and sample text to see matches as you type.
How it works
- Enter a JavaScript-compatible regular expression.
- Choose the flags that change how the pattern runs.
- Paste sample text and review the live matches.
When translators use it
Find tags, placeholders, repeated spacing, and QA patterns without sending text away.
What to know
It uses your browser’s JavaScript regular-expression engine, so syntax may differ from CAT tools.
