What is Google AI Mode?

AI Mode changes how you use Google. More than a search engine, it becomes a real conversational assistant powered by artificial intelligence. How does this new Google interface change the way you look up information (what we call AI Search)? And what are the real effects on the web ecosystem? Semji walks through this shift as it unfolds.

An AI chatbot built into Google?

Definition of Google’s new feature: AI Mode

AI Mode introduces a conversational mode into Google Search, combining the logic of a search engine with the fluency of a chatbot powered by Gemini 3

• “AI Mode: This new search mode extends AI Overviews with more advanced reasoning, thinking, and multimodal capabilities, so you can get help even with your most complex questions. Ask anything and get a relevant AI answer, then go further with follow-up questions and useful web links.” – Google

• Not only a fixed answer. You can keep the conversation going.

Google AI Mode: a conversation, not only an answer

Unlike classic search results, AI Mode supports ongoing interaction:

• Ask an initial question and get a synthesized answer;

• Refine the request with follow-up questions;

• Open the history of your exchanges at any time;

• Move between the conversation and the web pages that are cited.

The experience does not stop at a single answer. You can dig, specify, rephrase.

Built for complex questions

AI Mode was built to handle complex queries that need deeper reasoning:

• Automatic detection of multiple intents in your question;

• Account taken of context and of your personal situation;

• Structured answers matched to the complexity of the request;

• Intelligent organization of information so you can understand it immediately.

A concrete example: Instead of searching separately for “best restaurants Lyon,” “Lyon specialties,” and “vegetarian restaurants,” you can ask directly: “What are the best restaurants in Lyon that offer vegetarian versions of local specialties, with an average budget of €30?”

Complex questions and search intent

AI Mode was designed to answer compound or high-intent queries that need fine understanding and multivariable reasoning. A high-intent query is a search where the user has a precise, immediate goal.

• Relevant for complex, precise questions

• Automatic detection of multiple intents: goes further toward the exact search intent

• Takes the user’s context and situation into account, with more precise searches.

• “This lets you get help even with your most complex questions. Ask any question and get a relevant AI answer.” – Google

• “Ask your question in one go, with every detail that matters to you. AI Mode organizes the information intelligently and answers in a simple, intuitive way.” – Google

Multimodality

AI Mode can search and answer from text, image, audio, or video, integrating Multi Search and Google Lens.

• “Write, speak, take a photo, or upload an image. AI Mode uses advanced multimodal features to understand your question in depth, whatever form it takes.” Google

• Inputs: text, voice, photo/upload; multimodal understanding of the question.

• Outputs: structured answers + visuals + links to the web so you can go deeper.

• New in 2025: “search & explore visually” (for example: describe a style, get matching ideas and products).

Availability and rollout

Launched in the United States in May 2025, AI Mode now covers more than 40 countries, but it remains blocked in France for legal reasons.

• US announcement: 20 May 2025 @ “rolling out in the U.S”

• Worldwide expansion: 7-9 October 2025: +35 languages, +40 countries, 200+ territories, including many European countries.

• Still unavailable in France at the time this article was published.

How does AI Mode work?

AI Mode turns the Google search engine into an intelligent answer system based on the Gemini 3 model, able to understand, segment, and reason over complex queries written in natural language.

User experience and navigation in AI Mode

The AI Mode experience puts conversation at the center of search. The user opens a dedicated mode where the AI rephrases the query, shows synthesized answers with sources, and allows smooth movement between discussions and content.

• How do you turn on AI Mode? Access it via the “AI Mode” button or at https://google.com/ai

• Answer structure: summary + steps/tables + links to the web, chips to refine (for example criteria, budget, local).

• Navigation: open the cited pages to go deeper.

• Ongoing interaction: you can ask follow-up questions, available in a history you can consult (updated each time you reopen it).

The answer is usually organized into several parts: a direct summary, steps or tables when they help, and links to the web to go further. Contextual filters (budget, location, criteria) make it easier to refine the search.

AI Mode from a technical point of view

AI Mode runs on Gemini 3, combining parallel reasoning, controlled generation, and factual grounding. The whole system sits on an intelligent pipeline: query fan-out → RAG → grounding → contextual synthesis.

• Gemini 3 behind AI Mode, plus the option to use deep research

• Reasoning:

• Reformulation (query fan-out): the initial query is split into several simultaneous sub-queries

• RAG: integration of information from the web in real time, then coupled with natural generation

• Grounding: answers are attached to identified, cited sources (making the generative output more reliable).

• Synthesis: generation of a complete, concise answer that is updated on each new consultation.

• Agentic capabilities: the AI acts as an intelligent agent, able to take initiative to complete a goal the user defined.

Limits of AI Mode

For all its power, AI Mode is still constrained by performance, access, and regulation. Its capabilities vary with Gemini versions, server load, and safety considerations.

• AI hallucinations: Built-in citations limit AI hallucinations without removing them. Users still need to check sources directly.

• Context window: short memory (about 32,000 tokens on the public version).

• Premium features: Deep Research and Deep Think are reserved for Gemini Pro and Ultra plans.

• Content filtering: automatic blocking of domains considered unsafe or unreliable.

These limits change with the system’s regular updates.

Continuity of Google’s AI-driven evolutions

AI Mode sits on the “Search → AI-first” path, a response to massive adoption of AI uses and fierce competition, with visible effects on classic search and on publishers.

What is the concrete goal of AI Mode?

Google’s stated goal is to offer a better user experience for complex questions, and to add agentic capabilities that help users complete concrete tasks.

• “Power users told us they want AI answers for even more of their searches.” – Google

• Go further than AI Overviews

• Offer a more powerful end-to-end search experience than AI Overviews, through advanced reasoning and multimodality, to handle more complex questions and guide the user with links and follow-ups.

The difference with AI Overviews

AI Mode goes further than the AI Overviews (AI Overviews) already present in classic search:

• A dedicated conversational interface vs. a one-off summary card;

• Advanced multi-step reasoning vs. a simple direct answer;

• Full multimodality vs. mainly textual processing;

• Conversation history vs. isolated searches;

• Native follow-up questions vs. a new search every time.

AI Overviews remains a complement to traditional results. AI Mode becomes the main interface for some types of searches, and can therefore be compared with other LLMs.

A response to rising competition?

The development of AI Mode, with conversational interaction and direct synthesis, positions Google as a response to the chatbot-style interfaces launched by competitors.

• ChatGPT already offers a conversational interface with its Search mode.

• Perplexity offers a search experience rebuilt entirely around AI.

• Claude, Gemini, and other assistants are gaining popularity.

• Users are adopting these new ways of looking up information at scale.

• Google’s distinction rests on the deep integration of Gemini 3 and of its vast internal databases.

Google is responding by integrating Gemini deeply into its historic search engine. Its advantage is access to those vast internal databases and to the most complete web index in the world.

What is the impact on classic search?

AI Mode changes the search and online-visibility ecosystem at a fundamental level. Long dominated by classic SEO, based on ranking on the results page, Google Search is moving toward a model where the automated answer takes precedence over the list of links.

• This shift gives rise to the concept of GEO (Generative Engine Optimization), which pushes content creators to optimize for AI understanding and inclusion

• Direct organic traffic to traditional sites tends to decline

• The zero-click concept is on the rise

• The new goal: appear in sources and citations.

Content creators now have to optimize not only for ranking, but for citation and inclusion in answers generated by the AI.
