What is Google AI Mode?

Google AI Mode is an AI assistant that answers your questions by pulling information from across the web. It understands context, remembers what you’ve asked before, and gives you direct answers instead of a list of links.

You’ll see it in Google Search as ‘AI Mode’ above your search results, alongside “Images”, “Videos”, “Tools”, etc., or through the conversational interface in the Google app where you can have back-and-forth discussions with the AI.

This represents a complete departure from the search engine experience we’ve all got used to over the past two decades. Instead of giving users the familiar list of blue links and website snippets, you’re starting a dialogue where you can ask follow-up questions, receive clarifications on ambiguous requests, and get anticipated suggestions based on your search history and personal data. The whole aim is to handle nuanced, multi-part queries that would typically require visiting several different websites and piecing together information yourself.

Google claims that AI mode: “expands what AI Overviews can do with more advanced reasoning, thinking and multimodal capabilities – so you can get help with even your toughest questions. You can ask anything on your mind and get a helpful AI-powered response with the ability to go further with follow-up questions and helpful web links.”

This shift is a response to the growing threat of AI-powered search competitors like ChatGPT, which have begun to eat into Google’s previously unassailable dominance of the online search market. While Google still maintains a commanding 93.57% share of overall search traffic, and receives ~373x more searches than ChatGPT, the picture looks very different in the rapidly growing AI chatbot space. Here, ChatGPT dominates with 79.83% market share, while Google’s Gemini accounts for just 1.94% – a concerning position for Google as conversational AI search becomes more mainstream.

However, Google AI Mode isn’t just another AI-powered search engine. It has one key advantage over its competitors – baked-in integration with the rest of Google’s ecosystem of services. It will be able to pull from your Gmail, Calendar, Maps history, and other personal data to provide contextually relevant answers to your queries – something others currently have no counter to.

Why it matters.

Google AI Mode has huge implications for how we will find and consume information going forward. The days of opening multiple tabs and cross-referencing information from different sources may be gone, giving users the ability to complete complex research tasks through one ongoing conversation.

For many queries there may be no need to visit external websites at all – and this is a massive concern for businesses who rely on organic search traffic for their leads, sales or brand awareness. AI Overviews now reach over 2 billion users per month, and have already been shown to lower click-through rates by 20-60%. AI Mode’s fully conversational interface is likely to reduce clicks even further.

While both AI Mode and AI Overviews use artificial intelligence to enhance Google’s search experience, they serve fundamentally different purposes and offer distinct user experiences.

AI Overviews provide AI-generated summaries that appear above (and sometimes below) traditional search results, maintaining the familiar blue links beneath them. Users still get the classic search experience, but with an AI-powered summary at the top.

AI Mode, on the other hand, creates a fully conversational interface that doesn’t include the traditional 10 blue links of organic search results. It’s an end-to-end AI search experience similar to ChatGPT, where users interact entirely through conversation rather than clicking through to websites.

Google has even started prompting users in AI Overviews to continue their queries in AI Mode.

Here’s how they compare:

This is a question that confuses many people, as both are Google AI products with overlapping capabilities. The key difference is in their purpose and where they live.

Gemini is Google’s standalone AI chatbot – similar to ChatGPT or Claude. You access it through gemini.google.com or the Gemini mobile app. It’s a general-purpose AI assistant for tasks like writing, coding, analysis, and creative work. Think of it as Google’s competitor to ChatGPT.

AI Mode is built directly into Google Search. You don’t need to visit a separate website or app – it appears as a tab within your normal Google search results. Whilst AI Mode is powered by the same Gemini 2.5 technology, it’s specifically designed for search tasks and has direct integration with Google’s search index, allowing it to access real-time web content.

Here’s the breakdown:

In practice: You might use Gemini to draft a business proposal or analyse a spreadsheet, but you’d use AI Mode within Google Search when you want to research “best electric cars under £40,000” and have a conversation about specs, reviews, and availability.

Both are powered by Google’s Gemini technology, but they’re optimised for different use cases. For most search-related tasks, AI Mode is the more natural choice because it’s integrated where people already search – Google.com.

As of December 2025, AI Mode is powered by Gemini 3 Flash, Google’s latest fast and efficient AI model. Gemini 3 Flash combines the advanced reasoning capabilities of the Gemini 3 Pro model with optimised speed and cost-efficiency, making it ideal for the real-time conversational experience of AI Mode.

What’s Gemini 3?

Gemini 3 is Google’s third generation of AI models, released in November 2025. It represents a significant leap in reasoning, multimodal understanding, and autonomous task execution compared to previous versions. The “Flash” variant is specifically designed for high-frequency, low-latency tasks whilst maintaining frontier-level intelligence.

In simple terms: Google’s AI now thinks more clearly, works faster, and can actually complete tasks for you rather than just answering questions — whether you’re working with text, images, or video.

When you ask AI Mode a question, it doesn’t just search for that exact phrase. Instead, it automatically thinks of dozens of related questions you might also want answered. For example, if you search “best electric car,” it might also consider “most reliable electric vehicles,” “cheapest EVs,” and “electric cars with longest range.” This approach captures not just what you asked, but what you probably meant to ask.

Multi-Stage processing with query fan-out.

AI Mode uses a technique called “query fan-out” where it breaks down your question into multiple subtopics and runs several queries simultaneously. This allows it to dive much deeper than a traditional Google search.

Behind the scenes, AI Mode uses multiple AI systems working together, each specialised for different tasks. One might be excellent at summarising information, another at comparing products, and another at translating languages. The system automatically chooses which AI tools to use based on your specific question, then combines all their responses into one comprehensive answer.

For example, you search, “Best smartphones for photography under £500”

• Comparison AI analyses camera specs across different phone models and ranks them by photo quality
• Summarisation AI condenses hundreds of photography reviews into key strengths and weaknesses
• Recommendation AI filters results based on your £500 budget and previous searches for camera equipment
• Synthesis AI combines all this information into a single response: “Based on your photography interests and budget, here are the top 3 camera phones under £500, with the iPhone SE recommended for portrait mode and the Google Pixel 7a for low-light photography…”

Rather than you having to visit separate review sites, comparison charts, and price-checking tools, AI Mode does all this research simultaneously and presents one unified answer.

Deep personalisation.

AI Mode creates a digital profile of your interests and behaviours by analysing your Google activity – your search history, emails, calendar appointments, Maps usage, and more. This means that when you and a colleague ask the exact same question, you might get completely different answers tailored to your individual preferences and needs.

Advanced capabilities.

AI Mode comes with several specialised search modes:

Multimodal understanding.

AI Mode is natively multimodal, meaning it can pull information from text, videos, audio transcripts, and images, then remix this content into new formats. A video might supply a quote, a podcast could provide a data point, and an infographic might become part of a text-based answer — all synthesised into a single, coherent response. At present, Youtube is the single most cited domain for Gemini, so video is clearly incredibly important for AI search visibility.

This changes everything for businesses trying to be found online. It’s no longer enough to just rank for specific keywords on your website. Your content needs to be useful across many different searches and contexts. Success means having information that AI can pick up and cite, whether that’s from your blog posts, product videos, podcasts, or social media — wherever your brand appears online.

Google officially launched AI Mode in the UK on July 28, 2025, making it the third market to receive the feature after the United States and India. The UK rollout skipped the Search Labs experimental phase entirely, rolling out directly to all users.

In December 2025, Google upgraded AI Mode globally to use Gemini 3 Flash as the default model, bringing significantly improved reasoning capabilities and faster response times to all users.

How to access AI Mode in the UK.

UK users can access AI Mode in three ways:

• On Google.com – Look for the “AI Mode” tab that appears alongside “All,” “Images,” and “Videos” in search results.
• In the Google app (Android and iOS) – An AI Mode button appears in the app interface.
• Android home screen widget – Optional widget for quick access.

Unlike the US launch which started in Search Labs, UK users have immediate access without needing to opt in.

Adoption statistics.

The early adoption numbers show significant user interest:

• Over 80 million users globally have already accessed AI Mode (as of July 2025).
• 1.25% adoption rate across the US and India rollouts.
• Sessions 38% longer in AI Mode compared to traditional search.
• Queries 2-3x longer than traditional search queries.
• Over 100 million monthly active users in Q2 2025.

Google also announced plans to expand AI Mode to 20+ languages by the end of 2025, signalling aggressive global expansion.

What this means for UK businesses.

For UK businesses, the AI Mode launch brings both opportunities and challenges:

• Traffic concerns – Zero-click searches are likely to rise significantly. Because AI Mode answers queries directly within the interface, many users won’t need to click through to websites. Early US data suggests traffic drops of up to 25% for some publishers.
• Multimodal optimisation -
Content must now be optimised across text, images, and video. Sites that rely solely on text-based SEO may find themselves excluded from AI Mode citations.
• Measurement challenges -Google has started rolling out dedicated generative AI visibility reports in Search Console, but this is limited to impression data, making it difficult to track AI Mode performance separately from traditional search. However, you can filter for longer queries (10+ characters) as a proxy for conversational AI searches.

The message is clear: UK businesses need to start adapting their SEO strategies now, not waiting to see how AI Mode performs. The competitive advantage will go to those who optimise early.

Google AI Mode represents the most significant transformation in search since Google’s inception — a complete paradigm shift that fundamentally changes how people find information online and how businesses get discovered.

With the UK launch on July 28, 2025, and the December 2025 upgrade to Gemini 3 Flash, AI Mode is no longer a future concern – it’s here now, and adoption is growing rapidly. In January 2026, Google extended Gemini 3 to become the default model for AI Overviews as well, bringing frontier-level AI reasoning to over 2 billion monthly users. Early data shows 80+ million users globally have already engaged with AI Mode, with sessions 38% longer than traditional search.

The shift to AI Mode is inevitable, but it’s not insurmountable. Businesses that understand these changes and begin adapting now will maintain their competitive advantage. Those who cling to outdated SEO practices risk being left behind entirely.
