Meta AI (FAIR) — User Count: 630 million

NoteThe source directly confirms the exact claim. The source states 'WhatsApp dominates Meta AI usage with approximately 630 million active AI users, representing a stunning 63% of all Meta AI interactions.' This matches the claim's exact stored value of 630,000,000 users and the context that this represents 63% of all Meta AI interactions. The temporal alignment is also correct—the source is dated as of Q1 2025 (May 2025 data shown), which aligns with the claim's 'as of 2025-03' timeframe. The numeric format equivalence (630 million = 630,000,000) and the percentage match (63%) both confirm the claim.
