What are examples of AI search engines?
A concise, sourced look at AI search experiences, including Perplexity and Google’s AI features in Search, plus how they differ from assistants without web access and classic result lists.
Examples of AI search engines and answer experiences include Perplexity and Google’s AI features in Search (AI Overviews and AI Mode). You may also encounter offerings such as ChatGPT Search. These products differ from traditional result lists by generating an answer and prominently linking supporting sources, and they differ from assistants without web access by grounding responses in current web content. Always open the cited sources to verify claims.
Quick examples and what they do
Perplexity
Perplexity describes itself as “an AI-powered search engine” that answers questions by searching the web and providing conversational responses with citations and links to the original sources. It emphasizes real-time sourcing from the web and shows citations so you can verify information. The service also lets users choose among leading AI models. See Perplexity’s description for details and current scope (Perplexity Help: What is Perplexity?).
Google AI features in Search
Google integrates generative AI into Search through AI Overviews and AI Mode. According to Google’s documentation, these features surface relevant links alongside a response produced by the system to help people find information quickly and explore supporting websites. AI Overviews aim to get users to the gist of complex topics and provide a jumping-off point with links. AI Mode helps with complex comparisons, reasoning or multi-step exploration, and may use a “query fan-out” technique that issues related searches to identify supporting pages and display a wider, more diverse set of links than classic web search. Availability varies by query; Overviews are only shown when Google’s systems determine they add value. See Google’s official guidance (Google Search Central: AI features).
ChatGPT Search
ChatGPT can search the web for current information and provide links to sources. Search responses may include inline citations; opening the citations or source links lets you check what supports the answer. This is a web-connected search mode, rather than proof that every assistant response uses live search. Availability and usage limits can vary (OpenAI: Searching the web with ChatGPT).
How AI search differs from assistants without web access and classic results
AI assistant without web search
Some assistants answer from their internal model knowledge only. They don’t fetch current web pages, and you may not see live citations or links you can click to check. These responses can be useful for background, but they may miss the latest developments and offer fewer verification cues.
Web-grounded AI answers
Web-grounded experiences retrieve information from current web sources and usually provide citations or links so you can verify claims. For example, Perplexity states it sources content from the web in real time and supports answers with citations and links (Perplexity Help: What is Perplexity?). Google’s AI Overviews and AI Mode similarly “surface relevant links” and may expand the diversity of links shown versus classic results by issuing multiple related searches during generation (Google Search Central: AI features).
Traditional result list
Classic search typically returns a ranked list of links and snippets. You do the synthesis yourself by clicking into pages. AI answer experiences reverse that: they synthesize first, then show links to support or deepen exploration.

Practical tips for evaluating any AI search engine
- Open the cited sources and skim at least two to confirm the answer reflects the pages.
- Check whether the links include a diversity of publishers, not just one site (Google Search Central: AI features).
- Try multi-step follow-ups (for example, “compare option A vs B for [use case] with sources”).
- Note when the system shows no citations. Treat unsupported claims cautiously and search for a primary source.
- Be aware that availability and interface can change. Re-test periodically.

Compact checklist
- Pick one real query you care about (work or life).
- Run it in Perplexity and in Google’s AI features (when available for your query), plus any other tool you use.
- Open at least three cited sources from each answer; verify dates and claims match the pages.
- Ask one clarifying follow-up and note whether the tool keeps context and still cites sources.
- Record what you would change or verify with an expert before acting.
FAQ
Are clicks from Google’s AI Overviews or AI Mode reported in Search Console?
Yes. Google states that sites appearing in AI features are included in overall Search traffic and reported in the Performance report under the “Web” search type (Google Search Central: AI features).
Can site owners control whether their pages appear in Google’s AI features?
Google explains that robots.txt directives for Googlebot control crawling for Search, and preview controls like nosnippet, data-nosnippet, max-snippet, or noindex can limit what is shown; see the documentation for specifics and trade-offs (Google Search Central: AI features).
