Citation log, day by day
Which name each engine returned for the title, on each day between 25 September 2026 and 26 September 2026, by market. Days with no run are shown as gaps and are not filled in from the day before: an answer engine is not observed until it is asked.
Who each engine named, by day
A cell reading no single name means the engine answered but refused to pick one person: that is the answer it gave, and electing the first name it happened to list would be inventing a ranking. Only the prompts that ask about the title are counted here; the prompts about the field as a whole are in the full log.
