Introduction to the tool and how to use it
The repeated-digit filter finds numbers where one digit repeats often (or reaches an exact count) — for example, numbers containing 3 identical digits, or repeat numbers like 111, 8888.
Note: only digits 0-9 are counted; signs and decimal points are ignored; with at least selected, higher counts match more easily.

How to use
- Paste numbers into the input box; commas, spaces, line breaks, or any symbol can separate them.
- Choose the digit to count: pick a specific digit (such as 1), or keep any digit — then the most frequent digit in that number is used.
- Set the repeat count and choose at least or exactly as the match rule.
- Choose the filter mode: keep matches or remove matches.
- Click start; the text box on the right outputs results using the separator, the table below lists each row as index / number / repeated digit / count (copyable in place), and CSV can be downloaded.
