Can it catch?

Is your AI quietly cutting corners — results that look tailored, logic that slacks off? This page preps an exam for the checking tool you built: plant known errors into a copy of your data — flip a digit, drop a row, shift a date — and see at a glance which ones it misses. Everything runs in this browser; no file is uploaded anywhere.

3Drilled copy & answer sheet

The drilled copy (CSV) and its answer sheet (JSON) will appear here. Feed the copy to your tool — then come back and score its report in step 4.

4Score your tool's report

Paste what your tool reported on the drilled copy (any text — error list, log, summary). Scoring is evidence-based: a fault counts as caught if the report mentions the planted wrong value or the affected row's key.
