900 million weekly active users. That's where ChatGPT stands in a16z's sixth edition of their Top 100 Gen AI Consumer Apps report, up 500 million from a year ago. The report, published March 10, maps out a consumer AI landscape that looks radically different from even six months ago.
The headline numbers tell one story: ChatGPT remains 2.7x larger than Gemini on web and 2.5x larger on mobile. But the more interesting story is everything shifting underneath those totals.
The Winners and Losers Are Surprising
Claude grew paid subscribers 200% year-over-year. Gemini grew even faster at 258%. But ChatGPT is still 8x larger than Claude and 4x larger than Gemini in paid subscriptions, so those growth rates are coming off much smaller bases. About 20% of ChatGPT's weekly web users also use Gemini in the same week, suggesting people are shopping between models rather than committing to one.
The real casualty is standalone image generation. Midjourney dropped from the top 10 all the way to rank #46. The reason is simple: ChatGPT and Gemini now bundle image generation directly into their chat interfaces. Why pay for a separate tool when your chatbot does it? DALL-E as a standalone product is in the same boat.
Music and voice tools bucked this trend. Suno held at #15 and ElevenLabs kept its rank because their capabilities haven't been replicated well by the big chatbots yet. That's the pattern: if a general-purpose AI can absorb your feature, you're in trouble. If it can't, you're safe for now.
"AI Tool" No Longer Means What It Used To
a16z had to expand their definition of what counts as a gen AI app, and the reason tells you everything. CapCut has 736 million monthly active users and now depends on AI as a core feature. Notion's paid AI attachment rate (the percentage of paying customers who also pay for the AI add-on) jumped from 20% to over 50% in one year.
This is the most important trend for anyone choosing tools: the line between "AI tool" and "regular tool with AI" is gone. Canva, Notion, and CapCut are all on this list now, not because they're AI startups but because AI became central to what they do. For users, this means you're probably already using more AI tools than you think.
Coding Agents Are the Fastest-Growing Category
Claude Code hit $1 billion in annualized revenue in just six months. OpenAI's Codex reported 2 million weekly active users growing at 25% per week. Lovable, Cursor, and Bolt represent what a16z calls "vibe coding" - AI agents that build working software rather than just generating text.
Revenue for these coding tools keeps climbing even as traffic growth slows, which suggests the people using them are getting serious value and paying for it rather than just experimenting.
The agent trend extends beyond coding. OpenClaw, an open-source agent project, hit 68,000 GitHub stars in weeks and was acquired by OpenAI in February. Manus was acquired by Meta for roughly $2 billion in December 2025. Genspark raised a $300 million Series B and crossed $100 million in annual recurring revenue.
Geography Is Splitting the AI World
One finding that doesn't get enough attention: AI adoption per capita is highest in Singapore, followed by UAE, Hong Kong, and South Korea. The US ranks 20th despite producing most of the products. China has its own parallel ecosystem with DeepSeek, Doubao, and Kimi. Russia developed a separate market around Yandex Browser (71 million monthly users) and Sber's GigaChat after sanctions cut off Western tools.
For the platforms, the strategic divergence is clear. ChatGPT is building a super-app with 220+ integrations across 13 categories, including Expedia, Instacart, and Zillow. It's testing ads and planning a "Sign in with ChatGPT" identity layer. Claude is going the opposite direction with roughly 160 curated connectors focused on financial, developer, and scientific tools. Only 41 apps overlap between the two catalogs, about 11% of their combined offerings. They're competing for different users.
