- Mention the regex flavor (PCRE, JavaScript, POSIX) since escaping rules differ.
- Paste a few real sample strings so the pattern is tuned to your actual data.
- Ask for the non-greedy version if you're matching inside larger text blocks.

أسئلة شائعة
- Will the regex work in any language?
- Regex syntax varies slightly by engine; specify JavaScript, Python, PCRE, etc. so escaping and flags are correct.
- Can it explain a regex I already have instead?
- Yes, paste the pattern into the clipboard field and ask it to explain rather than generate one.
