About this data
Every statistic on this page is attributed to a named source and dated. AI usage numbers move fast, and platforms report on different schedules and definitions — weekly active users, monthly active users, downloads, and visits are not interchangeable, so each figure states which metric it is. Where market-size forecasts differ by research firm, we cite the firm and the figure rather than averaging them.
