A billion people use Gemini. The number to watch is 63%

On August 11, @sundarpichai posted Google's newest milestone: more than a billion people now use the Gemini app every month. He called it "our fastest growing product ever, and our 14th to hit the 1B-user mark." Josh Woodward, the VP who runs the app, followed with a thread on what Google learned from the first billion, and the thread is where the useful information lives.

The billion comes with fine print

Monthly active users is the friendliest metric in tech. It counts anyone who opened the app once in the past 30 days, whether they asked a single question or worked in it all day. ChatGPT crossed a billion monthly users back in June, and OpenAI has since moved to quoting weekly actives, a harder bar to clear. Google also didn't say how many of its billion pay for a subscription, an omission the tech press flagged within a day.

None of that makes the number hollow. Gemini reached a billion faster than any Google product before it, at a company with fourteen products at that scale. The app had 400 million monthly users in May 2025 and 900 million at I/O this past May, so the last hundred million arrived in under three months. Argue with the metric if you want. The curve is steep either way, which is presumably why the post landed one day before Made by Google, where the company teased task automation across 40 Android apps.

The stat worth stealing from Woodward's thread

Woodward wrote that the goal remains making Gemini "the most personal, proactive, and powerful assistant," and backed it with usage numbers. In a follow-up he noted more than 100 million active users on Apple platforms, with Mac power users prompting about twice as often as people on other surfaces. The app generates roughly 150 million images a day.

The number I keep coming back to is quieter: 63% of users now talk directly to Gemini. In Gemini Live, one session in five goes past voice into camera or screen sharing. Google is about to roll out more than 60 regional dialects to feed the habit.

That 63% is a behavior change, not a product stat. Two years ago, talking to your phone mostly meant setting a timer. Now the majority of a billion-user app's audience speaks to it, and Google is investing in dialects because people apparently want the assistant to understand them the way a neighbor would. Pichai's post tells you about Google's distribution machine, which puts Gemini wherever Google already is. Woodward's tells you what ordinary people do once the app is in front of them. They talk to it.

What a spoken answer means for your business

When a customer asks a question out loud, the answer comes back out loud, and nobody reads ten search results to you. The assistant mentions one or two businesses, and either you're in the answer or you're absent. That's a different game from ranking on page one, and most local websites aren't built for it. An assistant can't quote your prices if they live inside a photo of a flyer, and it can't confirm you serve St. Charles if your service area appears nowhere in plain text.

The fix is unglamorous:

• Put services, prices, hours, and service area in plain text on your site, not in images or PDFs.
• Answer the questions people actually ask out loud, like "do they handle emergency calls" or "how fast do they quote," in full sentences on the page.
• Keep your Google Business Profile current, since assistants lean on it for local answers.

One purchasing note from the other side of this story: a billion monthly users is a headline about Google's reach, not evidence that Gemini is the right model for your quoting workflow. Pick tools by task, not by user counts.

We look at both sides of this in New Face Design's free process audit: where AI would actually save you hours each week, and whether an assistant asked about your trade would mention you at all. Most owners are surprised by the second answer.

A billion people now open one AI app every month. The 63% tells you how they'll be asking about you.
