Not only does it have the most visits and users, but it also has the highest stickiness and app-store ratings among competitors. It\u2019s a true omnichannel, multi-audience tool.<\/p>\n<p><strong>Gemini<\/strong>, the runner-up, passed 700 million visits, and also leads in download numbers, which continue to be higher than ChatGPT&#8217;s. Its daily stickiness, however, is the lowest of all apps. As Gemini is a Google product, I suspect all signs point to Google pushing installs of this app via their Android OS, resulting in many installs and no uses.<\/p>\n<p>While MAU is still very much on ChatGPT&#8217;s side, I advise SEOs to continue watching the Gemini download trend.<\/p>\n<p>Google, as a competitor, might motivate more users to download the app, getting it installed on more devices than ChatGPT eventually. If that happens, there&#8217;s a chance Google will manage to shift the user base to its favor, and that&#8217;s also something we need to be aware of. However, as said, remember to also watch stickiness and MAU before making any quick decisions.<\/p>\n<p><strong>Claude.ai<\/strong> and Google&#8217;s (them again) <strong>AI Studio<\/strong> show impressive growth MoM of 18.6% and 12.5% respectively. Both are still very far in terms of numbers from ChatGPT, but if their growth continues, they might be able to close the gap in the future.<\/p>\n<h3>The most visited AI tools websites: 12-month trend<\/h3>\n<p>Let&#8217;s start with web usage. Website traffic over time gives a great view of each AI tool&#8217;s growth trend and can help estimate metrics like visibility and potential traffic from them in the future. Here are the top 5 AI tools websites&#8217; traffic in the last 12 months:<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-205900\" src=\"https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-top-ai-sites-monthly-visits.png\" alt=\"Monthly visits to top ai websites\" width=\"1396\" height=\"483\" srcset=\"https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-top-ai-sites-monthly-visits.png 1396w, https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-top-ai-sites-monthly-visits-300x104.png 300w, https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-top-ai-sites-monthly-visits-1024x354.png 1024w, https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-top-ai-sites-monthly-visits-768x266.png 768w\" sizes=\"(max-width: 1396px) 100vw, 1396px\" \/><\/p>\n<p>Aside from ChatGPT.com reaching 5.84B visits in August, it has also reached almost 100% growth compared to September 2024. In terms of <a href=\"https:\/\/www.similarweb.com\/blog\/marketing\/marketing-strategy\/traffic-share\/\">traffic share<\/a>, Similarweb data for August 2025, shows that ChatGPT is getting <strong>69% of the total traffic to AI tools.\u00a0<\/strong>This is while all other AI tools&#8217; sites are still under 1 billion visits a month.<\/p>\n<p><strong>DeepSeek<\/strong> has declined over 8% MoM, dropping over 30 million visits in August and <strong>losing a total of 300 million monthly visits<\/strong> (-50% of its monthly traffic) since February 2025. Smaller players like Quark, Doubao, and Replit are visible but still very far behind.<\/p>\n<h3>Traffic sources to the top AI tools<\/h3>\n<p>The chart below shows each AI tool&#8217;s traffic sources split in August 2025. It&#8217;s easy to see how all AI tools rely heavily on direct traffic (65%-70%), while organic search and other mediums are less prominent, with an average of 20% traffic share.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-205899\" src=\"https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-sources2.png\" alt=\"Top AI tools traffic sources\" width=\"1200\" height=\"394\" srcset=\"https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-sources2.png 1200w, https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-sources2-300x99.png 300w, https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-sources2-1024x336.png 1024w, https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-sources2-768x252.png 768w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/p>\n<p>Grok and Gemini are the only ones who seem to benefit nicely from referral traffic, but let&#8217;s face it: They are the only ones that can utilize it in a large mass, thanks to Google search and X.com. The other AI tools do not enjoy the benefit of having huge organizations backing them up, at least not at that scale.<\/p>\n<h3>The most used AI tools: MAU breakdown<\/h3>\n<p>Now, let&#8217;s inspect the August AI tools&#8217; App usage data: The following chart shows the global MAU of each leading app:<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-205894\" src=\"https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-ai-mau.png\" alt=\"AI apps MAU for August 2025\" width=\"600\" height=\"371\" srcset=\"https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-ai-mau.png 600w, https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-ai-mau-300x186.png 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<p><strong>App Usage Comparison:<\/strong> ChatGPT leads with 388M MAUs, adding 10M monthly active users MoM. Gemini grew 10% MoM, but is low on daily stickiness. Deepseek has been declining since May 2025, losing a total of 10M monthly active users in the last 3 months.<\/p>\n<p>With so many users choosing one app month after month (after month), I wonder if there will ever be any need for &#8220;Perplexity optimization&#8221; on general queries rather than specific niches that Perplexity serves the most. For now, I don&#8217;t see any reason to make assistant-specific adjustments.<\/p>\n<h2>Top AI Tools by country: Which countries use AI the most?<\/h2>\n<p>With ChatGPT as the leader of AI tools, I want to see a breakdown of its usage by country. That can help me plan and prioritize my optimization efforts for the different markets better.<\/p>\n<p><a href=\"https:\/\/www.similarweb.com\/blog\/marketing\/seo\/chatgpt-monthly-visits\/\">ChatGPT\u2019s monthly traffic<\/a> continues to grow in all regions, with most leading countries also growing in traffic share. When looking at MoM data, I can see that only Indonesia, Germany, and Canada show decreased usage, while most other countries continue expanding:<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-205901\" src=\"https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-countries-august.png\" alt=\"ChatGPT traffic share by country\" width=\"583\" height=\"365\" srcset=\"https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-countries-august.png 583w, https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2025\/09\/attachment-countries-august-300x188.png 300w\" sizes=\"(max-width: 583px) 100vw, 583px\" \/><\/p>\n<p>For SEO purposes, and to answer the question I asked myself at the beginning of the paragraph, it seems that English-speaking markets are the best route to invest in, but finding solutions to assist the markets in Asia with their language-specific issues can help build and expand brand visibility in AI and drive traffic from ChatGPT to your website.<\/p>\n<p>Now it&#8217;s time to take a deeper look into each country&#8217;s performance. Is your main market in the US? The UK? China? Do you know where your audience goes to get answers?<\/p>\n<h2>Top AI tools in the U.S. by web and app engagement<\/h2>\n<p>The U.S. remains the biggest market for generative AI.

Gemini, DeepSeek, and Perplexity are even more desktop\u2011heavy (&gt;70% of traffic), reflecting use in professional and academic settings.<\/p>\n<h2>AI Product developments that affected usage trends<\/h2>\n<p><strong>ChatGPT:\u00a0<\/strong>OpenAI <a href=\"https:\/\/openai.com\/index\/introducing-gpt-4-5\/\">launched <strong>GPT\u20114.5\u00a0Turbo<\/strong><\/a> in early August, offering faster responses and better handling of complex tasks. The update caused a spike in both downloads and visits. The company also expanded its voice\u2011chat feature to more markets, contributing to mobile engagement.<\/p>\n<p><strong>Google Gemini:\u00a0<\/strong>Google <a href=\"https:\/\/blog.google\/products\/gemini\/gemini-2-5-deep-think\/\">rolled out <strong>Gemini\u00a0Ultra<\/strong><\/a>, an enterprise tier integrated with Workspace, enabling document summarization and data analysis within Gmail and Drive. Despite the new feature, app stickiness remained low, hinting at a gap between curiosity and daily utility.<\/p>\n<p><strong>DeepSeek:\u00a0<\/strong>DeepSeek partnered with hardware manufacturers in China to preinstall its assistant on new laptops, helping boost desktop traffic but not necessarily app adoption. The site\u2019s negative month\u2011over\u2011month growth suggests users may be sampling alternatives.<\/p>\n<p><strong>Perplexity:\u00a0<\/strong>Perplexity continued its rapid iteration, <a href=\"https:\/\/www.perplexity.ai\/hub\/blog\/perplexity-launches-enterprise-pro\">launching <strong>Perplexity\u00a0Pro<\/strong><\/a> with citation support and multimodal queries. The service\u2019s high growth in downloads (+47.34% MoM) and strong stickiness reflect user satisfaction with its ability to provide sources for answers.<\/p>\n<p><strong>Claude:\u00a0<\/strong>Anthropic\u2019s <strong>Claude\u00a03<\/strong> models gained traction among enterprise users due to strict safety policies and privacy controls. The absence of a consumer\u2011facing app limits mass adoption, but rising web traffic (+18.64%) shows corporate curiosity.<\/p>\n<h2>Conclusion<\/h2>\n<p>August 2025 data confirm yet again that ChatGPT.com is far ahead of its competitors, both in web visits and <a href=\"https:\/\/www.similarweb.com\/blog\/research\/apps\/app-engagement-guide\/\">app engagement<\/a>. A surge to <strong>5.846\u00a0billion<\/strong> visits shows that this is one <a href=\"https:\/\/www.similarweb.com\/blog\/marketing\/seo\/website-migration\/\">website migration<\/a> that didn&#8217;t have a negative effect on the new domain&#8217;s traffic and growth. If anything, it highlights ChatGPT\u2019s centrality in the new AI ecosystem.<\/p>\n<p>Competition is fierce: Google Gemini, DeepSeek, and Perplexity each attract hundreds of millions of visits and continue to innovate. It&#8217;s important to keep an eye on them as well and study their growth patterns and trends, and be ready for any upcoming change in this race.<\/p>\n<p><strong>Key takeaways:<\/strong><\/p>\n<ol>\n<li><strong>ChatGPT\u2019s dominance<\/strong> is unquestionable: it leads in visits, app MAUs, and engagement, thanks to continuous improvements and wide accessibility. Research, test, and measure as much as you can, and make sure to stay up to date with its new abilities and product developments.<\/li>\n<li><strong>Regional dynamics matter:<\/strong> the U.S. and India drive usage, while Europe shows cautious but growing adoption. Investing your efforts there may not bear fruit in one day, but it has great potential for the future.<\/li>\n<li><strong>Engagement vs.\u00a0reach:<\/strong> high download numbers don\u2019t guarantee daily use. Gemini\u2019s low stickiness highlights the need for compelling features and better onboarding.<\/li>\n<li><strong>Emerging trends:<\/strong> Pro tiers (Gemini Ultra, Perplexity Pro) and safer models (Claude 3) show the market moving toward professional and enterprise applications, growing potential reach for B2B brands that invest in GEO and AI visibility.<\/li>\n<\/ol>\n<p>SEOs should remember these insights when selecting which AI tools to optimize for, and how.

Google\u2019s AI Studio also grew 12.53%, and Perplexity\u2019s visits rose 5.42%. In contrast, DeepSeek\u2019s traffic fell nearly 9 %, continuing a decline that has cut its visits by more than half since early 2025.<\/p>\n<p><strong>Which AI tool has the highest daily user engagement (\u201cstickiness\u201d)?<\/strong><br \/>\nChatGPT leads by a wide margin: 43.87% of its app users return daily. Perplexity and DeepSeek show moderate stickiness (~20%), while Google Gemini\u2019s is only 5.59%. High stickiness suggests users rely on ChatGPT for routine tasks, whereas lower figures indicate more exploratory or one\u2011off usage.<\/p>\n<p><strong>How does ChatGPT\u2019s usage compare with Google\u00a0Gemini\u2019s?<br \/>\n<\/strong>Although Gemini has more downloads than ChatGPT, its user base is smaller and less loyal. ChatGPT had 5.846\u202fbillion visits and 388.02M MAUs, whereas Gemini had 723.3\u202fmillion visits and 47.56M MAUs. ChatGPT\u2019s daily stickiness (43.87%) dwarfs Gemini\u2019s 5.59%, indicating that many Gemini installs are never used or used only once<\/p>\n<p><strong>What are the top countries using ChatGPT?<\/strong><br \/>\nThe United States contributed the largest share of traffic to chatgpt.com in August 2025, at 15.09%, followed by India (9.31%), Brazil (5.31%), the United Kingdom (4.30%), and Indonesia (3.72%).<\/p>\n<p><strong>Are there free AI chatbots available for businesses?<\/strong><br \/>\nYes. According to a SaaS\u2011marketplace guide, many AI chat tools offer free plans: ChatGPT can be used as a basic chatbot at no cost, xAI\u2019s Grok is free on X (Twitter), and Google\u2019s Bard (based on Gemini) is free in some regions. Dedicated platforms like Tidio and Chatbase also provide free tiers, though advanced features require paid plans<\/p>\n<p><strong>How much do AI tools cost?<br \/>\n<\/strong>Prices vary widely. ChatGPT offers a free tier, while ChatGPT Plus costs about $20 per month. Other generative tools have similar models: Runway offers free credits and paid plans, Tidio has a free tier, and corporate chatbots like Copilot cost around $30 per user per month. Pay\u2011as\u2011you\u2011go models like DeepSeek and Perplexity charge per usage, often by the token.<strong><br \/>\n<\/strong><\/p>\n<p><strong>Which AI tool should marketers and SEOs focus on?<br \/>\n<\/strong>For research and content creation, ChatGPT remains the most versatile choice, thanks to its high adoption, wide\u2011ranging capabilities, and continuously improving features. SEOs should also watch Perplexity, which excels at providing research\u2011backed answers and is growing rapidly, and Claude, which prioritizes safety and privacy (a key consideration for regulated industries).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>New month &#8211; New data!
