Repeated number checker

Find numeric values repeated across pasted passages so you can compare their contexts.

Applied rule

Extracts numeric tokens and lists values appearing more than once with line references.

Boundary

Repeated values can be intentional; this flags review candidates, not contradictions.

Result

Enter your own values or load the documented example, then run the local check.
