I've spent the last two years studying consumer AI trends.

Yesterday, our team @a16z published our latest report on the top 100 AI products (by usage).

My biggest surprises - and what to learn from them ⬇️
1️⃣ DeepSeek falls off

DeepSeek traffic significantly declined, now down 22% from peak on mobile and 40% on web.

Of DeepSeek's top 5 countries, usage fell in the U.S., Russia, India, and Brazil - and was flat only in China.

Once the novelty wore off, users did not retain. Image
2️⃣ Grok surges

On the other end of the spectrum, @xai's Grok had a big debut - at #4 on the web list and #23 on the mobile list.

Grok 4 and companions (Imagine released too late for inclusion), released in July, were as real unlocks - driving a jump of nearly 40% on mobile! Image
3️⃣ Google relative ranks

Four Google products made the top 50 on web. After Gemini (#2), AI Studio (developer sandbox) ranked #10, NotebookLM at #13 and Google Labs (Veo 3) at #39.

Two surprises here: (1) NotebookLM keeps growing!; (2) dev-facing products are now mainstream. Image
4️⃣ Claude and Meta struggle on mobile

Despite significant distribution on web, Claude and Meta AI have struggled to take off on mobile, while Perplexity and Grok have soared.

This is more understandable for Claude as usage is heavily coding-related, but more confusing for Meta. Image
5️⃣ Vibe coding delta

For both Replit and Lovable, we tracked traffic to the builder products (.com,.dev) and separately to apps made on them (.app).

Traffic to the builder products dwarfs traffic to apps. Users are either vibe coding personal software, or buying custom domains. Image
6️⃣ Number of "All Stars"

14 cos made all five versions of our top 50 web list.

This is nearly 1/3 of the list - network effects (or at least data moats) are starting to emerge.

And, the All Stars are a mix of categories, geos, and models (proprietary vs. API vs. aggregator). Image

🚨 The @a16z consumer AI Top 100 is back!

For the sixth time, we ranked consumer AI websites and mobile apps by usage (monthly unique visits and MAUs).

This edition, we changed the rules. Here's why - and what the new list says about where consumer AI is heading 👇 Image
Image
For the first time, we're including AI-powered products - not just AI-native ones.

@CapCut, @Canva, @NotionHQ, @freepik, @picsart, @Grammarly all make the list.

If AI is core to the experience, we'll include it. In fact, three of the top 15 web products are not AI-native. Image
ChatGPT leads - but it's no longer a one horse race.

ChatGPT is AI for most consumers - it's 2.7x larger than Gemini on web and 28x larger than Claude.

But, Gemini, Grok, and Claude are all gaining share - especially of paid subscribers. Image

AI is here to transform marketplaces.

But it's not creating new ideas - it's taking old ones, and finally making them work.

Marketplace categories that were previously graveyards are now greenfields, with space to build massive companies.👇 Image
First - what are these graveyard categories?

Think talent marketplaces, home repair, personal services (legal, tax), etc.

Shared traits are high value, infrequent transactions, that have required real manual coordination to make a match. This leads to high CACs and low LTV.
AI can change this in a few ways:

1️⃣ Serving as the middleman - plugging in where a human was needed before for intake, support, etc.

2️⃣ Allowing the marketplace to offer a new "product" to either buyers or suppliers, that uniquely attracts or retains them

Some examples ⬇️

🚨 Introducing the AI Apps 50: Startup Edition

Ever wondered how startups are spending their money when it comes to AI?

Our team at @a16z worked with @mercury to crunch the numbers and rank the top applications by spend.

The list + what we learned from it👇 Image
First of all, how did we assemble this list?

We took data from Mercury's 200k+ customers (many are early stage startups) and ranked the vendors based on total spend between June and August 2025.

We then pulled the top 50 AI-powered applications from this list.

Takeaways ⬇️
1️⃣ Horizontal apps have a slight lead over vertical (60% of the list)

This includes general assistants (ex. @perplexity_ai) and SIX different meeting support tools (ex. @fyxerai).

But, it also encompasses creative tools and vibe coding tools that are used in roles across orgs.

OpenAI just released the largest-ever report on how consumers are using ChatGPT.

It looks at millions of (anonymized) messages over the last 3 years to analyze usage evolution over time.

Key takeaways 👇 Image
1⃣ Usage engagement is increasing.

Older cohorts initially saw a dip in usage throughout 2023 (when new model/feature release was slow)

...but since then, every cohort has seen increasing usage (message volume) over time.

This is also true looking at usage / WAU in a cohort. Image
2⃣ For users on non-enterprise accounts, usage is largely non-work related.

This has only increased over time and for newer cohorts.

In June '24, 53% of usage was non-work related, Now (June '25), it's upwards of 73%. Image

In the AI era, consumer startups are on a new trajectory.

The best B2C companies are exceeding 100% net revenue retention - which was previously only possible in B2B.

At @a16z, we call this "The Great Expansion." How companies achieve it👇
First, what does 100%+ NRR mean?

Net revenue retention = % of revenue that is retained over a period of time after accounting for churn and expansion.

If it's over 100%, the company is making MORE money from a cohort of customers over time.
In the pre-AI era, B2C companies almost never exceeded 100% NRR.

Why? Most users were monetized via a flat monthly subscription or ads. Usage-based pricing was rare.

So user retention = revenue retention. And since some users churned, NRR was less than 100% (and often <50%!) Image

🚨 Announcing the latest @a16z top 100 AI apps!

This marks the fifth edition 🎉 of our global ranking of consumer AI websites and mobile apps by usage.

And in my opinion, it was our most surprising list yet!

Our top takeaways + who made it 👇 Image
Image
1️⃣ Consumer AI is starting to stabilize.

This edition of the list saw only 11 new names on the web rankings*, compared with 17 on our last edition.

The mobile list saw more new entrants, as the App Store cracked down on ChatGPT copycats!

*excl. Google properties - more below! Image
Image
2️⃣ Google makes big moves

For the first time, we ranked Google domains separately - and four properties made the web ranks:

- @geminiapp (#2)
- @googleaistudio (#10)
- @notebooklm (#13)
- @googlelabs (#39)

NotebookLM's traffic has continued to ⬆️ since its viral moment. Image
