Frequently asked questions
Do I need to know regex?
No. You describe the result in plain English and the tool writes the regular expressions for you, explaining every step.
What can it do instantly?
Extract or remove emails, URLs, phone numbers, dates, IP addresses, prices and hashtags; remove blank lines, duplicates, HTML tags and extra spaces; replace words; keep or drop lines containing a word; change case and sort.
Can I reuse the regular expressions?
Yes. Every step shows its regex with a copy button, and “Copy regexes” copies the whole recipe.
Is my text sent anywhere?
In Instant mode everything runs in your browser. In “My own chatbot” mode only a short sample goes into the prompt, and only when you paste it into a chatbot yourself.
