Most Popular AIs and Their Usage by Country

Determining the "most popular" artificial intelligence (AI) systems involves looking at user adoption, market share, and application areas, often measured by user base, website visits, or survey data. Below, I summarize the most prominent AIs, their primary uses, and available data on user percentages by country, based on recent statistics and trends. Note that precise, up-to-date percentages for every AI across all countries are limited, so I’ll provide the most reliable data available, supplemented by broader trends where specific figures are unavailable.

1. ChatGPT (OpenAI)

• Description: A conversational AI model based on GPT architecture, used for text generation, answering questions, and task assistance.
• Primary Uses:
  • Customer service (chatbots)
  • Content creation (writing, marketing)
  • Education (tutoring, research)
  • Personal productivity (task automation)
• Popularity and User Percentages:
  • United States:
    • 46% of generative AI users in the U.S. used ChatGPT in the past month (CivicScience, May 2025).
    • Estimated 60 million monthly active users (MAU) in the U.S., part of a global 600 million MAU (court documents cited on X).
  • Global:
    • ChatGPT had 14.6 billion visits in 2023, making it the most visited AI tool globally.
    • 800 million weekly active users worldwide (X post, May 2025).
    • Brazil: 82% of residents use AI technologies, with ChatGPT likely a significant contributor (KPMG study).
    • India: 81% AI usage, again with ChatGPT as a major player.
    • Netherlands: 58% AI usage, with 53% awareness, suggesting strong ChatGPT penetration.
    • South Korea: 85% subjective AI knowledge, indicating high ChatGPT adoption.
    • China: 82% AI knowledge, but ChatGPT’s usage is limited due to restrictions; local alternatives dominate.
    • Japan: Only 25% have high/moderate AI understanding, suggesting lower ChatGPT penetration.
• Notes: ChatGPT dominates globally due to its versatility and accessibility. Its usage is highest in countries with high internet penetration and fewer restrictions, like the U.S., Brazil, and India. In China, government restrictions limit its reach.

2. Google Gemini

• Description: Google’s multimodal AI model, succeeding Bard, capable of processing text, images, audio, and video.
• Primary Uses:
  • Search enhancement (Google Search)
  • Productivity tools (Google Workspace)
  • Developer tools (APIs for app integration)
  • Consumer applications (voice assistants, smart home devices)
• Popularity and User Percentages:
  • United States:
    • 37% of generative AI users in the U.S. used Gemini in the past month, closing the gap with ChatGPT (CivicScience, May 2025).
    • 350 million MAU globally, with significant U.S. contribution (court documents).
  • Global:
    • 241 million visits to Google Bard (predecessor to Gemini) in 2023, ranking 6th among AI tools.
    • 1.4 billion daily queries globally, indicating strong adoption in search-related AI (X post, May 2025).
  • Other Countries:
    • Specific percentages are scarce, but Gemini’s integration into Google’s ecosystem (Search, Android, Chrome) suggests high usage in countries with strong Google penetration, such as the U.S., India, and Europe.
• Notes: Gemini’s growth is fueled by Google’s vast ecosystem, making it a strong competitor to ChatGPT, especially in search and productivity applications. Its adoption is likely high in English-speaking and tech-forward countries.
