Regex Tester & Validator

Matches any text segment starting with a character other than 'a' and lazily extending to the nearest closing parenthesis. The non-greedy quantifier ensures the shortest possible match up to the first ')' on each line, aided by global and multiline flags. Useful for extracting or filtering parenthetical content like citations (e.g., conference references) or annotations while excluding matches that begin with the letter 'a'.
