Regex Builder: Generate & Test Regex Patterns from Plain English

Why Regex Is Still Hard

Regular expressions are powerful but notoriously hard to write and debug. A misplaced quantifier can match everything or nothing. Vincony's Regex Builder lets you describe your pattern in plain English and generates a tested regex with explanations.

Plain English to Regex

import vincony

client = vincony.Client(api_key="YOUR_KEY")

result = client.tools.regex_builder(
    description="Match email addresses ending in .edu or .ac.uk",
    test_strings=[
        "[email protected]",        # should match
        "[email protected]",      # should match
        "[email protected]",         # should not match
    ],
    language="python"
)

print(f"Pattern: {result.pattern}")
print(f"Explanation: {result.explanation}")
for test in result.test_results:
    print(f"  {test.input}: {'✓' if test.matched else '✗'}")
