How we count

• We monitor 34 AI and technology sources continuously and publish original write-ups of what matters.

• One story means one article published on AI2Day. Each edition covers a single UTC calendar month.

• Once a month ends its figures are frozen and never recalculated, so a number you quote today still reads the same in a year.

• Category and topic counts can exceed the story total, because a story may sit in more than one.
