  • What are the most popular AI search engines? The leading AI search engines include ChatGPT (700 million weekly active users), Google’s Gemini, Perplexity, Anthropic’s Claude, and Microsoft’s Copilot, each offering capabilities like research, coding, image generation, and content creation.
  • Why are AI search engines considered the future of search?

What are AI search engines?

AI search engines are search entities that use AI to help them synthesize information, process it, and deliver summarized responses for users. These engines tend to take a more conversational approach when engaging with users and deliver helpful, contextual information, rather than lists of links.

How do AI search engines work?

There’s a lot of nuance with AI search engines and how they work, but the basic operation looks like this:

  1. A user inputs their prompt or query into the AI search engine
  2. The engine, using its dataset and sometimes the web, searches through multiple sources to find information
  3. It then synthesizes all the information and summarizes it for the user
  4. The AI engine outputs the summary for the user

An important distinction to make with AI search engines is that they’re essentially doing the work for the searcher.

When you conducted your search on a traditional search engine in the past, you’d sift through links in the search results. You’d have to figure out which page looked the most relevant to your query, click on it and read the information from that page to make sure that it had the answer you were looking for. 

Now, AI search engines take all of that work out of the equation for the user. They’re the ones sifting through the pages, finding the information that’s most relevant and helpful, and delivering it to the user.

Are AI search engines the future of search?

Yes (at least part of it).

Search engines like Google and Bing aren’t going away anytime soon. Google especially has a stronghold over the market, which makes it difficult to surpass with any type of search engine.

That doesn’t mean, however, that AI search engines won’t be a part of the future. In fact, they’re very likely to play an important role in the future of search.

The main reason that AI search engines are the future of search is that they offer something unique that traditional search engines don’t offer: Conversation.

When you use a traditional search engine, there isn’t much interaction between you and the engine. You type your query in the search bar, and you look at the search results for the information. 

While Google has AI Overviews to help simplify the search experience, it doesn’t invoke a conversation aspect like AI search engines do.

Other AI search engines, like ChatGPT and Perplexity, create a conversation dynamic where you search a query, get information, and ask follow-up questions. It uses the context of the previously shared information to help further push the conversation.

This type of search experience is appealing to many people. Not only do the AI engines summarize the information for the user, but they can ask follow-up questions and get answers without having to do much extra work.

So, while AI search won’t be the only way to search in the future, it will still play a prominent role in the search experience and need to be accounted for.
