Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 126 of the 129 answers that named Microsoft 365 Copilot and are not a share of its labels.
293 of the 334 domain citations in answers naming Microsoft 365 Copilot came from somebody else's page.
Pages are listed as the models cited them.
Search figures are US estimates from DataForSEO, read October 5, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.
An email the morning each edition publishes: where this product moved, where it held, and by how much against the noise floor. One address, confirmed by a click; a stop link in every email.

What Microsoft 365 Copilot's own pages state, read October 5, 2026: clarity.microsoft.com/copilot, microsoft.com/bg-bg/microsoft-copilot/locale, microsoft.com/bg-bg/microsoft-copilot/copilot-101, microsoft.com/bg-bg/microsoft-365/modern-workplace, microsoft.com/bg-bg/microsoft-copilot/organizations. A claimed page can correct any of them.
Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Microsoft 365 Copilot's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Microsoft 365 Copilot, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.
A new claim receives the current edition's vendor brief for Microsoft 365 Copilot by email, built from the raw record of the edition. It shows:
Microsoft 365 Copilot is among the products AI models recommend first in Enterprise AI assistants this edition. Each badge says so in the buyer's words, names the edition, and links to the standing. The next edition issues a new badge; this one stays true as a record of October 2026.
Badges read on light and dark pages. Alt text carries the claim, the category, the edition and the index, so it stays a citation where the image does not load.
