Direct answer
No, there is no single switch that turns AI off across Google. You can hide AI Overviews in some situations by using the Web filter, and you can turn off certain Gemini and Search Labs experiments, but Google keeps AI Overviews and AI Mode on by default for most queries and regions [1]. What you can control is narrower than most people expect: which surface you search on, which experiments you opt into, and whether you use a browser or app that does not render AI panels [1].
Can You Actually Disable AI Overviews and Gemini in Google Search?
Partly — and the "partly" matters. AI Overviews are generated summaries that Google inserts above organic results for a wide range of queries, and Google's own documentation describes them as a default part of Search rather than an optional add-on you can uninstall [2]. There is no account setting labelled "turn off AI" in Google Search, and Google has consistently framed AI Overviews as core Search functionality rather than a toggleable feature [2].
The controls that do exist are indirect. The Web filter narrows results to plain text links and suppresses the AI summary panel for that query, which is the closest thing to a genuine off switch for many users [2]. Search Labs lets you disable experimental features you previously enabled, such as AI Mode experiments, but that only affects experiments you opted into — it does not remove AI Overviews from ordinary results [2].
Gemini is a separate product with its own settings. You can turn off Gemini Apps activity, delete your Gemini conversation history, and disable Gemini extensions, but those privacy controls govern data retention and app behaviour, not whether Search shows AI answers [2]. Treat "Gemini settings" and "Search AI settings" as two different control panels, because conflating them is the most common reason people think a toggle failed.
Why Does Google Keep Showing AI Results Even After You Change Settings?
Because the settings you changed were probably scoped to a different surface, device, or account than the one you are searching on [3]. Google applies AI features per product — Search, AI Mode, the Gemini app, Chrome, and Workspace each have their own controls — so disabling an experiment in Search Labs on desktop does nothing to the AI panel in the mobile app [3]. Signing out, switching profiles, or using a different browser profile can also restore defaults you thought you had changed.
Google has also been explicit that AI Mode is a default-available surface rather than an opt-in. It appears as its own tab alongside All, Images, and News, and Google's announcements describe it as an expansion of Search rather than a beta you join [3]. When a feature ships as a default surface, "turning it off" usually means avoiding that surface, not disabling it.
There are practical workarounds that behave more like real off switches than any setting does. Using the Web filter, bookmarking a plain-results URL, switching your default search engine in the browser, or using a search front-end that strips AI panels all reduce exposure [3]. None of them is permanent, and Google can change markup or rollout at any time, so expect to re-check your workaround after major Search updates [3].
If You Can't Switch AI Off Everywhere, How Do You Make Sure Your Own Writing Isn't Flagged as AI?
That is the question that actually matters for anyone submitting work. Whether Google shows you an AI summary has no bearing on whether your essay reads as AI-written to a detector — those are unrelated systems, and no browser setting changes how your draft is scored [4]. What changes the outcome is the text itself: its phrasing predictability, sentence rhythm, and the density of generic transitional language.
Turnitin's AI writing report gives a percentage plus highlighted segments, and it deliberately withholds a precise figure when detection confidence is low — a *% display means the signal fell below Turnitin's confidence threshold rather than that the text scored zero [4]. That distinction is routinely misread, and it is the main reason students either panic over a low-confidence flag or assume a clean-looking report means no risk at all [4].
The reliable approach is to check before you submit rather than after. Previewing the same report your instructor sees lets you see which paragraphs are flagged, rewrite those specific passages in your own voice, and re-check — a loop that is far more effective than guessing from a Google search result [4]. Keep your drafts, notes, and version history too, since context is what turns a flagged segment into a defensible one [4].
Turning off Google's AI panels is a partial, surface-by-surface exercise — but the AI signal in your own submitted document is something you can actually measure before it counts. That is exactly what turnitin0 was built for: upload your .docx, .pdf, or .txt draft and get back the same Turnitin AI detection report and similarity report your professor sees, typically in under 15 minutes, without adding your file to Turnitin's student paper database. Over 100,000 reports have been delivered to more than 20,000 students in the US, UK, Canada, Australia, New Zealand, and Ireland.

FAQ
Is there a hidden setting that turns off AI Overviews completely?
No. Google documents AI Overviews as part of Search rather than an optional feature, so there is no master toggle [1]. The Web filter is the most reliable way to get plain results for a given query.
Does turning off Gemini activity stop AI Overviews?
No. Gemini Apps activity controls govern conversation history and data retention in the Gemini app, not whether Search renders AI summaries [2]. They are separate systems with separate settings.
Why did AI results come back after I disabled them?
Most likely the change was scoped to one surface, device, or account. Search Labs experiments, the mobile app, and AI Mode each carry their own state, and signing in or switching profiles can restore defaults [3].
Does using the Web filter affect my Turnitin AI score?
Not at all. Your browser settings have no effect on how a detector scores your document; only the text itself and the detector's confidence threshold determine the result [4].
What does a *% AI score actually mean?
It means Turnitin's detection confidence fell below its threshold, so it displays an asterisk instead of a precise percentage. It is a low-confidence signal, not a confirmed zero [4].
