The Top 100 Most Used AI Apps in 2025

a16z is back with its fifth deep dive into the 100 most-used consumer AI apps, ranking the top 50 web and mobile products by monthly usage. This latest list reveals an ecosystem that’s beginning to stabilize while still leaving plenty of room for explosive new categories to emerge.

The Maturing AI Frontier

  • "The web list I think is the best way to track changes over time... We still had 11 new names, which sounds like a lot out of 50, but it's actually a big reduction from the 17 new names we saw 6 months ago. This reflects that the ecosystem is starting to stabilize a little bit more."
  • "When we look at these 14 all-stars, more than half of them are actually hosting or using other people's models or are model aggregators. This speaks to the fact that in consumer AI, the UI and product experience matter just as much as the model."
  • The AI chaos is calming. The rate of new companies cracking the top 50 is slowing, and a clear group of 14 "AI All-Stars"—including ChatGPT, Character.ai, and Midjourney—have appeared on every list for the past two years, signaling market consolidation.
  • Product, not just proprietary models, wins. Over half of the All-Stars build on top of third-party models, proving that a superior user experience and workflow can create a powerful moat. True network effects are also emerging on platforms like Civitai and ElevenLabs, which leverage community-generated models and voice libraries.

Vibe Coding’s Breakout Moment

  • "For many of the leading vibe coding platforms, they actually see 100% or above revenue retention in the first 3 months, which is very rare to see for any consumer or prosumer product."
  • A new category has exploded onto the scene. "Vibe coding" platforms like Lovable and Replit, which simplify app development, have stormed the web list. This trend, which barely registered a year ago, now represents one of the most dynamic new sectors.
  • Retention is off the charts. These platforms are demonstrating unheard-of revenue retention for consumer products (often >100% in the first three months), suggesting they are delivering immense value and are likely being adopted for professional and enterprise use cases.

The Global AI Chessboard

  • "You could argue that Chinese companies show up in two or even three pretty interesting ways on the list. The first are AI products that are built for China and used in China. The second category are startups developed in or around China but are built for the rest of the world."
  • Google is finally on the board. After adjusting its domain tracking, four Google properties landed on the web list, with Gemini hitting #2 (with ~10% of ChatGPT's web traffic) and developer sandbox AI Studio cracking the top 10.
  • China is executing a multi-pronged strategy. Chinese companies are succeeding with: 1) domestic-only apps like Kimi, 2) globally-focused products, especially in video (e.g., Kling), and 3) apps like Monica that find traction both at home and abroad.

Key Takeaways:

  • While the consumer AI space is maturing, the game is far from over. The data shows that while incumbents are solidifying their positions, breakout categories can still emerge from nowhere, and the global race between U.S. and Chinese firms is intensifying.
  • Product and Distribution Are King: Having a proprietary model is not a prerequisite for success. More than half of the top-performing "AI All-Stars" thrive by building superior user experiences on top of existing models, proving that UI and community are powerful moats.
  • Vibe Coding Is the New Killer App: The explosive growth and unprecedented retention of vibe coding platforms signal a major new trend. These tools are empowering a new generation of builders and rapidly bridging the gap between consumer and prosumer use cases.
  • The Platform Wars Are Just Beginning: Don't count the incumbents out. Google's strong debut with four products shows the fight for AI dominance is a multi-front war, while Chinese firms are proving adept at competing in both domestic and international markets simultaneously.

This episode reveals a consumer AI market in transition—stabilizing around established giants while new, high-retention categories like "Vibe Coding" signal where the next wave of growth and investment opportunities lie.

Deconstructing the Consumer AI Top 100

  • Olivia, the list's compiler, explains its purpose is to track what consumers are actually using in AI, capturing both free and paid usage to provide a real sense of what is capturing consumer imagination.
  • The methodology involves ranking every global website by monthly visits (using SimilarWeb) and every mobile app by monthly active users (using Sensor Tower), then filtering for the top 50 AI-native companies from each source.
  • Justine notes this list serves as an inspiration for users and a signal for investors, answering the common question: “What are people actually doing with AI?”

Market Stabilization and Emerging Trends

  • The web list, a more stable indicator than the volatile mobile app stores, featured 11 new companies.
  • Olivia highlights this is a significant reduction from 17 new names six months prior, suggesting the ecosystem is maturing and becoming less chaotic.
  • A key emerging trend is Vibe Coding, a term for AI-powered low-code/no-code development platforms. Companies like Lovable and Replit entered the list, signaling a new, powerful use case gaining traction.
  • Olivia observes: “The ecosystem is starting to stabilize a little bit more.”

The Enduring Dominance of AI Companionship

  • Despite the emergence of productivity tools, AI companionship remains a dominant category, with three new names (Juicy Chat, Joyland, and Rolemate) joining established players.
  • Incumbents like Character.ai, Janitor AI, and SpicyChat continue to hold strong positions, demonstrating the category's deep user engagement and retention.
  • This persistent trend underscores a core human need for connection that AI is successfully fulfilling, representing a durable and significant market segment for investors to watch.

Google's Multi-Pronged AI Offensive

  • Google made a significant impact, landing four distinct properties on the web list for the first time due to changes in how their traffic is tracked.
  • Gemini ranked #2, capturing about 10% of ChatGPT's web traffic and nearly 50% of its mobile traffic, driven heavily by Android users.
  • Surprisingly, AI Studio, Google's developer-facing sandbox, ranked in the top 10, indicating strong interest from builders.
  • NotebookLM (#13) maintained steady traffic, defying the narrative of being a one-time viral hit.
  • Google Labs (#39) also made the list, with its traffic spiking 15% in the month of the release of its video model, VEO, suggesting strong interest in generative video tools.

The Rise of Chinese AI Companies

  • Chinese AI companies are showing up in three distinct ways:
    1. Domestic Focus: Products like Alibaba's Quark and ByteDance's Doubao rank in the top 20, serving the massive Chinese market where competitors like ChatGPT are banned.
    2. Global Exports: Startups developed in China, particularly in image and video (e.g., Pika, Kling), are built for a global audience and are often inaccessible within China.
    3. Hybrid Model: Companies like Remini (a popular photo enhancer) are developed in China but find major audiences abroad, with Brazil and the US as its top two markets.
  • Justine adds that many Chinese models are also distributed through US-based platforms like Replicate or application layers like Crea, making their true influence harder to measure directly but still significant.

Vibe Coding: A High-Growth, High-Retention Category

  • The Vibe Coding category has expanded beyond early entrants, with Lovable and Replit now on the main list.
  • These platforms show exceptional financial metrics. Lovable, for instance, announced a $100 million ARR.
  • Crucially, data from Consumer Edge shows these platforms have over 100% net revenue retention in the first three months. This indicates users are not just trying the service but are upgrading plans and increasing their spending—a strong signal of product-market fit and potential enterprise adoption.
  • An interesting usage pattern emerged: traffic to the creation platforms (e.g., lovable.com) is much higher than traffic to the apps built on them (e.g., *.lovable.app). This suggests users are either deploying projects on custom domains or building valuable "personal software" for themselves and small groups.

The AI All-Stars: Pillars of Consistency

  • Olivia introduces the "AI All-Stars"—14 companies that have appeared on all five editions of the list over two years, demonstrating durable product appeal.
  • Key All-Stars include:
    • General Assistants: ChatGPT, Perplexity, Poe
    • Companionship: Character.ai
    • Creative Tools: Midjourney, Leonardo, ElevenLabs
    • Productivity: QuillBot, Gamma
    • Model Hosting/Community: Hugging Face, Civitai
  • A critical insight for investors: over half of these consistent performers are not building proprietary models. Instead, they are model aggregators or application-layer companies focused on superior UI, workflow, and community.

Unpacking Network Effects in AI

  • The discussion moves beyond the standard data network effect (more users -> better models).
  • Platforms like Hugging Face and Civitai demonstrate powerful community-based network effects. Users contribute models, datasets, and LoRAs (Low-Rank Adaptations, which are small files used to fine-tune models), creating a content moat that is difficult to replicate.
  • ElevenLabs exhibits a similar effect with its Voice Library, where users upload and share voices, creating a vast, user-generated asset library. Justine notes, “one of the reasons they love using 11 is there's thousands and thousands of voices you can choose from.”

The Prosumer Bridge: From Consumer Fun to Enterprise Value

  • A significant trend is the graduation of consumer AI tools into enterprise use cases.
  • Companies like Gamma (presentations), PhotoRoom (image editing), and ElevenLabs (voice synthesis) are seeing bottoms-up adoption within companies.
  • This prosumer model—where products serve both individual consumers and professionals—allows for organic, self-serve enterprise sales. An employee adopts a tool for personal use, brings it to their team, and it spreads, bypassing traditional top-down sales cycles.
  • This model creates a powerful growth loop, as enterprise use can drive further consumer awareness and adoption.

Future Outlook: Verticalization and New Frontiers

  • Looking ahead, Olivia predicts continued verticalization, where users choose different AI assistants for specific tasks (e.g., Grok for real-time info, Perplexity for research). Grok's debut at #4 on the web list underscores this trend.
  • The hosts anticipate growth in categories where model accuracy is critical and has only recently become reliable enough for mainstream use.
  • Key areas to watch for future list entries include:
    • Prosumer Productivity: Tools for financial modeling, spreadsheets, and email.
    • Education (EdTech): Where hallucination reduction is crucial.
    • Personal Finance & Health: Categories requiring high reliability and trust.
    • AI-Native Social: The search for the first major AI-centric social platform continues.

Conclusion

The consumer AI market is maturing, with durable "All-Stars" solidifying their positions. However, the rapid rise of high-retention categories like Vibe Coding and prosumer tools shows significant opportunities remain. Investors and researchers should focus on platforms building strong community network effects and those bridging consumer and enterprise use cases.
