Search Engines Without AI

The Short Answer

As of 2026-07-25, exactly one of the engines below publishes a dedicated endpoint whose stated purpose is turning its own AI features off: DuckDuckGo's No-AI host. DuckDuckGo describes it as working the same as search on duckduckgo.com, except all AI features are turned off and AI-generated images are filtered out (DuckDuckGo Help).

Google is the other engine with a clear, documented route — but it is a per-search mode, not a switch. Google's help page states that AI Overviews are a core Google Search feature, like knowledge panels and that features cannot be turned off, while describing its Web filter as one that displays only text-based links without features like AI Overviews (Google Search Help). So the honest framing is not “turn AI off in Google” — it is “search Google in a mode that does not show it, every time.”

Everything else is weaker than it is usually presented. Suppressing one named summary feature is not the same as an engine not using AI, and an engine that has never advertised an AI feature has not therefore promised it never will.

How This Page Decides

One rule: a claim about an engine appears here only if that engine's own documentation says it. Reviews, press coverage and community posts are not used as evidence about vendor behaviour, because they go stale silently and because AI features ship faster than third-party write-ups get corrected.

Each engine falls into one of three buckets:

• Vendor no-AI mode — the vendor publishes an endpoint or setting whose stated purpose is turning its AI features off.
• Partial — the vendor documents a mode or parameter that removes a named AI surface, but not AI across the product.
• No vendor doc located — no vendor documentation about AI controls was found for this review. This is not evidence the engine uses AI, and not evidence it does not. It means the claim is unverified, so no claim is made.

The last bucket is the one most comparison pages fill in with a green “No AI” tick. That tick is usually an inference from the absence of an advertised feature, which is not the same as a commitment.

What Each Vendor Documents

“Where results come from” matters as much as the AI column: an engine that resells another index inherits that index's coverage and its blind spots, whatever it does about summaries.

Three Things That Get Confused

1. “No AI summary” is not “no AI”

Ranking, spam filtering, query interpretation and result descriptions can all use machine learning without a summary box ever appearing. Brave says this outright: advanced machine learning models are used broadly and deeply across most parts of the technology stack that powers Brave Search. An engine can suppress its summary and still be full of AI. That is not a criticism of Brave — it is unusually clear about it, which is why it is quotable.

2. A lightweight endpoint is not an AI setting

DuckDuckGo's HTML and Lite endpoints are often listed as “AI-free versions”. They are stripped-down interfaces, and the thing DuckDuckGo actually documents as turning AI features off is its No-AI host — a different address with a different, published purpose. If you want the documented behaviour, use the documented endpoint.

3. No engine can promise AI-free results

Every claim above is about the engine's own features. None of them is a claim about the pages in the results, which are written by other people and increasingly by other people's models. DuckDuckGo is careful about this: it says it filters AI-generated images out and filters AI-generated content as much as possible — best-effort wording, not a guarantee. Any page promising you results with no AI-generated content in them is overselling.
