What it does
Paste a text and get a verdict on each claim in it, with a confidence score and the sources behind it. Instead of one true or false for the whole piece, you see exactly which sentence holds up and which does not. It first splits the text into single checkable statements and drops opinions. It labels each as a number, a date, a science finding or a definition, then looks for the best source type: official data for statistics, journals for research, records for history. Each claim is compared against at least two independent sources. Verdicts run from true to false, with unverifiable as its own result.
