Is Sited Better Than Scrunch AI? ChatGPT Hits 1 Billion Users

Short answer: for founders who want a fast, affordable read on their AI visibility, Sited is the better choice than Scrunch AI. Sited costs a single $50 payment and delivers a self-serve audit in minutes, while Scrunch AI is a subscription platform starting at $250 a month aimed at brand and agency teams running ongoing monitoring. The rest of this piece explains why that distinction matters more than ever, now that ChatGPT has crossed a genuinely enormous usage threshold.

What changed?

OpenAI has confirmed that ChatGPT has passed one billion weekly active users, a milestone tracked in detail by Keywords Everywhere's ChatGPT Updates tracker, which describes ChatGPT as having "recently crossed the 1 billion weekly user mark".

The growth curve behind that number is steep. The same tracker sets out the disclosed series: 200 million weekly users in August 2024, 400 million in February 2025, 700 million in August 2025, 800 million at DevDay that October, 900 million in February 2026 alongside 50 million paying subscribers, and now a billion.

That is roughly a fivefold increase in weekly users in about two years. This counts weekly actives, so it is not directly comparable with monthly-user figures such as Google's 2.5 billion for AI Overviews, a distinction flagged in Boot Camp Digital's September 2026 roundup, but the direction of travel is unmistakable: more people, more often, are asking a chatbot instead of typing into a search box.

This lands in the same week Semrush published its expanded 2026 AI Visibility Index, scaling from an initial 2,500 prompts to 126 million U.S. AI search prompts analysed from January through April 2026. That study found only 36 global brands maintained top-100 visibility across all four major AI platforms during every month studied, underlining just how uneven AI visibility already is, even before another few hundred million users pile in.

Why does this matter for your business?

A billion weekly ChatGPT users is not an abstract number. It means the pool of people who might discover your brand through an AI answer, rather than a traditional search result, has grown enormously in a short window.

The concentration data from Semrush's study makes the stakes concrete. Competitive opportunity varies significantly by industry: in News and Media, the three most visible brands accounted for 82.9% of total category visibility, while in Consumer Electronics the top three represented 76.9%, compared with Finance at 41.4% and Industrial at 42.2%. In some categories a handful of brands are hoovering up nearly all the AI visibility, while in others the field is still wide open.

If ChatGPT keeps growing at this pace, categories that look "open" today will not stay that way for long. Founders who wait to check whether their brand even appears in AI answers are giving away ground to competitors who are already testing and fixing their content for citability.

There's a second knock-on effect worth flagging. As more queries move into chat interfaces, the pages that get cited need to be genuinely quotable: clear claims, real data, direct answers near the top. Generic marketing copy simply does not survive the retrieval step that AI systems use to decide what to cite, which is exactly why brand-level AI visibility checks have become a routine part of the marketing toolkit this year, alongside traditional SEO, as Boot Camp Digital notes in its coverage of the shifting search landscape.

Sited vs Scrunch AI: which fits this moment?

This is where the choice of tool actually matters, and it's worth being honest about what each one is built for.

Scrunch AI is a genuinely capable platform for brands that need ongoing tracking. It monitors how a brand appears across AI engines and serves machine-readable pages to crawlers through its Agent Experience Platform, with coverage of roughly six engines including ChatGPT, Claude, Gemini and Perplexity (coverage of Google AI Mode, Meta and Copilot varies between its own pages). It also brings enterprise-grade extras: single sign-on, an Enterprise Data API, a dedicated go-to-market team, and a customer base backed by Series A funding. For a marketing team running continuous competitor benchmarking and citation analysis over time, that is a real strength.

The catch is cost and complexity. Scrunch AI's plans start at $250 a month billed annually ($300 month-to-month) for Starter, rising to $417 a month billed annually ($500 month-to-month) for Growth, with custom Enterprise pricing on top and a 7-day free trial to evaluate it. That is roughly £2,500 to £3,000-plus a year before you even reach the enterprise tier, and it assumes you want a dashboard to log into and manage continuously.

For the founder or small marketing team this article is written for, that is the wrong shape of tool at the wrong moment. Sited is a single $50 payment, not a subscription, and it starts with a free scorecard so you can see where you stand before paying anything. There is no trial clock, no onboarding call, no dashboard to maintain: you get a point-in-time audit with prioritised fixes in minutes. Given that ChatGPT alone has just added hundreds of millions of new weekly users, what most founders need right now is not a monitoring platform to run for a year, it is a fast, affordable, self-serve answer to "how visible am I in AI search today, and what do I fix first?" On that specific question, Sited is the clearer fit. If you haven't checked yet, you can run Sited's free audit at https://sited.online in the time it takes to read this article.

What should you do now?

Start by treating AI visibility as seriously as you treat your website's Google ranking. Run a scorecard or audit to see whether ChatGPT, Gemini or Perplexity even mention your brand when someone asks about your category.

Then look at your highest-value pages: pricing, comparisons, "best for" style content, and case studies. These are the pages most likely to get pulled into an AI answer, so they need clear, direct claims near the top rather than buried in the fifth paragraph.

Finally, revisit this every few months rather than once. Semrush's expanded study covers prompts analysed from January through April 2026 alone, and given how quickly usage is growing, visibility snapshots go stale fast.

Frequently asked questions

Is Sited better than Scrunch AI for a small business?

For a founder or small marketing team wanting a quick, low-cost read on AI visibility, yes. Sited's $50 one-time audit and free scorecard are built for self-serve speed, whereas Scrunch AI's subscription plans, from $250 a month, are aimed at brands running continuous monitoring with dedicated support.

How many people now use ChatGPT?

OpenAI has confirmed ChatGPT has recently crossed the 1 billion weekly active user mark, up from 200 million weekly users in August 2024, according to Keywords Everywhere's tracker.

Does this milestone mean I should stop worrying about traditional SEO?

No. Traditional search still matters, but the growth in ChatGPT usage means AI-driven discovery is now a parallel channel worth checking specifically, rather than assuming good Google rankings automatically translate into AI visibility.

What is the Agent Experience Platform Scrunch AI mentions?

It's Scrunch AI's system for serving AI-optimised, machine-readable pages directly to AI crawlers, sitting alongside its continuous brand monitoring across engines like ChatGPT, Claude, Gemini and Perplexity.

How concentrated is AI visibility across industries?

It varies a lot. Semrush's study found the three most visible brands in News and Media accounted for 82.9% of category visibility, versus 41.4% in Finance, meaning some sectors are far more open to new entrants than others.
