Overview
- Daily active users reached 2.7 million on October 17, up from roughly 775,000 four weeks earlier, according to Similarweb.
- New installs climbed to about 300,000 per day from under 200,000, compared with just 4,000 daily downloads on the same date last year.
- The rise coincides with the September 25 introduction of Vibes, a short‑form AI‑generated video feed embedded in the Meta AI app.
- Similarweb found no meaningful search or advertising signal tied to the spike and notes its models may miss internal Facebook or Instagram promotions.
- In the same snapshot, ChatGPT fell 3.51%, Grok 7.35%, and Perplexity 2.29% in DAUs, as coverage of OpenAI’s invite‑only Sora may have nudged users to sample Meta AI.
