Description

Turn a plain-language description into a ready-to-use regular expression. The on-prem AI at federicocalo.dev generates the pattern, explains it step by step and shows test cases (input → match yes/no) so you can instantly see whether it does what you need. No cloud fallback: your data stays on the on-prem infrastructure. The popup also checks the pattern against the browser regex engine and lets you copy it with one click.
