A regex pasted into a code review or dropped above a function as a comment doesn't need a full token-by-token tutorial explaining every character, it needs one clear sentence describing what the pattern is actually for, matches a valid US phone number, matches an email address with a required domain, the kind of concise summary that documents intent rather than walking through syntax. This tool generates a single plain English description summarizing what a regex pattern matches overall, built for documentation rather than a step-by-step breakdown of each token.
