Output

Example use cases
Email validation in user signup flows
“I need to check if user-submitted email addresses match our standard email format before processing them. Can you test a batch of these email addresses against the pattern '^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$' to see which ones are valid?”
Extracting phone numbers from text
“I'm getting customer messages with phone numbers in different formats. Can you check if this text contains a phone number matching the pattern '^\+?1?\d{9,15}$' and let me know if it matches and what the captured number is?”
Validating API response data formats
“Our payment system returns transaction IDs in a specific format and I need to make sure they're correct before processing. Can you test whether 'TXN20240115ABC12345' matches this regex pattern '^TXN\d{8}[A-Z]{3}\d{5}$'?”
