How popular is each AI chatbot?

Different trackers measure popularity differently (website visits, app users, surveys), so exact numbers vary. The broad picture is consistent:

ChatGPT leads. First Page Sage’s November 2026 report puts ChatGPT at about 52% of AI chatbot market share. OpenAI said ChatGPT crossed 1 billion weekly active users on 31 July 2026 (as reported).
Gemini is second. The same report puts Gemini at about 26%, and Google’s Gemini app was reported to cross 1 billion monthly active users in August 2026.
Claude is growing fastest. First Page Sage estimated Claude’s three-month user growth at +22%, the highest in its list.
DeepSeek, Grok, Perplexity and Copilot have smaller shares of chatbot website traffic, though Copilot and Meta AI reach many people through apps they already use.
