Google Gives Schools an AI Off Switch, But Not for Search Users

By Priya Raman

Google told schools last week that they can opt student accounts out of AI products — but if they reject AI entirely, they must also turn off search. That trade-off, confirmed by Google's new AI policy for schools using its apps, has sharpened a question every search marketer now faces: can anyone use web search without AI at all?

Google's vice president for education, Chris Phillips, gave The New York Times the framing that drove the week's headlines: "search and AI are deeply integrated." The Guardian and others concluded there is no longer a way to use Google search without AI. For brands that depend on organic visibility, that claim deserves a careful reading rather than a panicked one.

The context matters. AI has become ubiquitous, and it is also meeting pushback. Research cited by King's College London reports over 40% of people are limiting their AI use as popularity starts to wane. People reject it for personal, ethical or environmental reasons, including Gen Z users and critics of generative AI's energy footprint. Yet everyone still needs to look things up.

How does a search engine actually work?

Google search is a web search engine, and everything under the hood runs on algorithms — sets of instructions for a computer. Six main components make a query return results in milliseconds:

• Crawling: harvesting documents published on the web
• Indexing: breaking documents into efficient data structures
• Spam detection: filtering out content with no genuine value
• Ranking: ordering results by relevance to the query
• User interactions: helping users form queries (autocompletion) and consume output (snippets, AI summaries)
• Evaluation: measuring whether a change improves search quality

These components are not static. Engineers and information retrieval researchers constantly refine them.

How much AI is inside web search?

All six components likely involve machine learning and neural networks — AI systems trained to analyse data, learn patterns and make predictions. So, strictly speaking, there is no way to use any search engine "without AI."

What people mean today is generative AI: systems trained on enormous datasets that generate new content from prompts. Retrieval-augmented generation, which combines a large language model with web content retrieved by the search engine, powers the conversational experience. That is the technology behind Google's AI Mode and AI Overviews.

The practical weaknesses are documented. The model's training data is vast but updates less frequently than the web index. Links in AI summaries are attached after the answer is generated, and that component can make mistakes. Searchers who see AI Overviews access fewer sources overall, and overreliance on AI — trusting an answer without verifying it — is a well-known phenomenon Microsoft Research has flagged.

Can users search without AI summaries?

Here the answer splits by vendor. Google offers no official switch to disable AI Overviews and other generative features. There is, however, a working workaround: appending "&udm=14" to the search URL forces results into the "Web" tab, which strips AI Overviews and other snippets. Users must add the parameter manually, so developers have built browser plugins and automations around it. In Mozilla Firefox, and in Chromium browsers such as Brave, Chrome and Opera on desktop, users can set a custom search engine that applies the parameter on every Google search.

Rivals have gone further. DuckDuckGo, Brave Search and Ecosia each offer a "non-AI mode" that deactivates AI summaries by default, and in some cases can filter out AI-generated images.

Where do the results come from?

Maintaining a web index is expensive. The web changes constantly, and keeping searchable information fresh requires enormous computational resources. Only a few organisations manage it at scale; Google's and Microsoft Bing's indexes dominate worldwide.

Brave Search operates its own independent index. DuckDuckGo combines multiple sources, including its own crawler and results sourced from Bing. The OpenWebSearch.eu project is building an independent open European search infrastructure and publishes a web index so others can build their own engines on top of it.

What does this change for marketers?

The short answer to "search without AI" is no — every engine uses AI somewhere. But generative AI specifically can be switched off, and a meaningful share of users, backed by a 40% figure on AI avoidance, now have the tools to do it. Google has made AI summaries the default and shows no sign of an opt-out; its competitors treat the opt-out as a feature. Content strategies built only for the AI Overview layer will miss the growing audience that arrives via the plain blue links.
