ChatGPT has a massive user base, with estimates in late 2025 and early 2026 pointing to over 800 million weekly active users (WAU), while some projections estimate Monthly Active Users (MAU) to be between 1.2 to 1.5 billion by early 2026, with significant growth driven by its viral adoption and features like image generation, even reaching hundreds of millions of mobile app users alone. 

But user counts don't tell you how people actually use it. In May 2025, OpenAI published the biggest study ever on AI usage. They analyzed 1.5 million conversations and found that 49% of usage is people asking questions, 40% is getting work done like writing or coding, and 11% is just exploring ideas.

Key User Metrics & Growth

• Weekly Active Users (WAU): Over 800 million as of late 2025/early 2026, doubling its base in just months.
• Monthly Active Users (MAU): Estimates suggest 355 million in 2025, with projections for 2026 reaching 1.2-1.5 billion.
• Mobile App Users: 557 million monthly active users on mobile by August 2025.
• Website Visits: 775.6 million visits in October 2025 alone, with total visits to web properties exceeding 5.8 billion.

How People Actually Use ChatGPT: OpenAI's 2025 Study

OpenAI published the biggest study on AI usage in May 2025. They analyzed 1.5 million ChatGPT conversations from 700 million weekly users. Here's what they found.

The Three Types of Usage:

Asking (49% of all usage):

• People seeking information and factual answers
• Getting advice on decisions
• Consulting ChatGPT like an advisor
• Most valued category according to user ratings

Examples: "What are the pros and cons of React vs. Vue?" or "How should I approach this salary negotiation?" With half of ChatGPT usage being people asking for recommendations and advice, brands naturally want to know if they show up in these conversations. One easy way to do this is by using an AEO tool that shows what people are asking, whether your brand appears in ChatGPT answers, and how it's presented.

Doing (40% of all usage):

• Writing emails, reports, code, and content
• Planning projects and organizing info
• Task-oriented work where ChatGPT generates outputs
• About one-third of "Doing" is explicitly for work

Examples: Drafting documents, debugging code, creating presentations

Expressing (11% of all usage):

• Personal reflection and exploration
• Creative experiments and play
• Conversations without specific goals
• Just chatting and exploring ideas
   

Work vs. Personal Split:

30% of ChatGPT usage is work-related. That includes:

• Writing (top work task: emails, reports, documentation)
• Coding and debugging
• Research and fact-checking
• Data analysis

70% is personal/non-work usage. That includes:

• Learning new skills (26% of US adults)
• Entertainment and exploration (23% of US adults)
• Personal decisions and advice
• Creative hobbies
   

For Developers Specifically:

79% of developers use ChatGPT for work. That's higher than any other profession.

What developers do with it:

• Code generation and boilerplate (38% of full-stack devs)
• Debugging and error messages (57% of junior devs)
• Documentation writing
• Learning new languages and frameworks
• Code review and optimization

A Harvard/MIT study found that consultants using GPT-4 completed tasks 12.2% faster and produced 40% higher quality work than those without AI.
 

Who Uses ChatGPT:

The gender gap closed in 2025. In January 2024, only 37% of identifiable users were women. By mid-2025, usage matches the general adult population.

Age breakdown:

• 18-29 years: 43% have used ChatGPT (highest)
• 30-49 years: 30% adoption
• 50-64 years: 20% adoption
• 65+: 6% adoption

Education level:

• Postgraduate degree: 52% have used it
• Bachelor's degree: 51%
• Some college: 33%

• Direct visits: 79.77%
• OpenAI.com referrals: 5.79%
• Google organic search: 5.10%
• Social media and other: 9.34%

Desktop vs. Mobile:

76.22% of traffic comes from desktop, 23.78% from mobile. Desktop dominance makes sense for a productivity tool. Most coding and writing happens on computers.

Mobile usage varies by region. In Sub-Saharan Africa, mobile makes up 57% of sessions. In the US, Europe, and Japan, it's 70%+ desktop.
