Highlight your data, get a working regular expression back — no regex expertise required
Paste up to 4000 characters and highlight the exact substrings you want to capture — the AI derives the regex from your examples rather than from a written description.
Several independent AI agents each return their own pattern, so you can compare approaches and pick the one that generalizes best instead of trusting a single black-box answer.
Every candidate pattern is applied to your text instantly, showing the full list of matched strings so over-matching and missed entries are obvious at a glance.
Click a highlighted string to remove it and the agents re-run, letting you steer the result by tuning examples in seconds.
