Natural-language to verified regex
Describe what you want to match. Get a regex that is actually tested — with a live red/green panel, multi-flavor warnings, and a plain-English explainer.
Verified, not guessed
Every generated pattern is compiled and run against your samples. The red/green test panel shows real matches — never trust an unverified regex again.
Multi-flavor aware
Targeting JS, PCRE, RE2, or POSIX? We validate per flavor and warn you about differences — lookbehind in RE2, shorthands in POSIX, possessive quantifiers, and more.
Explain + edit loop
Paste any regex for a plain-English, token-by-token breakdown. Then refine it by describing the change you want. Generate and debug in one place.
Free, instant testing
The test panel is always free and runs locally — no signup, no model calls. It is the retention hook, not a cost center.
