Wrong About You: what five AI engines state about 70 software vendors

Answers captured under method v1.1 on 22 to 23 Sep 2026 for the Absence Index release 2026-09 (DOI 10.5281/zenodo.22907695). Statements were extracted and classified under the published Record rules and checked against each vendor's own public pages. Every flagged statement is published with its engine, run, question, capture date and the vendor page it was checked against. Team review of the flagged statements is in progress; rows change only if the review changes them, and every change is logged in the public ledger.

2,922 engine statements, provisionally classified: 1,924 true, 113 wrong, 5 stale and 880 unverifiable. Wrong or stale among verifiable statements: 118 of 2,042 (5.8 percent, 95 percent Wilson interval 4.8 to 6.9). Pricing carries most of them. ChatGPT, Claude, Perplexity, Google AI Overviews and Google AI Mode each have their own row in the study.

Every vendor's record is on its Absence Index page, with the engine, the runs that stated it, the page we checked and its review state. The 118 flagged statements remain provisional; 0 are analyst verified. Each row says "Team review: in progress".
