Google’s Gemini and Microsoft’s Copilot have successfully made AI chatbots mainstream and serve as viable alternatives to standard web search engines. In turn, the standard search engines from those companies (along with alternative ones) have adopted some AI elements.

AI can palpably improve the web search experience, and I’ve found Copilot a productivity booster when it comes to research. Whereas I used to have to pore over multiple web pages in standard search results, I can now often find the kernel of knowledge I’m after with just one text prompt. Additionally, if an initial answer isn’t quite what I'm looking for, AI search bots keep track of my previous requests to give my follow-up questions context. That means I don’t have to keep rephrasing my whole query the way I do with standard search or legacy AI tools like Amazon's Alexa and Apple's Siri.

But Copilot in Bing and Google AI Overviews aren't our focus here. Instead, we are looking at search engines that wholly run on generative AI.

Generative AI and chatbots typically rely on large language models (LLM) that train on a set of information with a specific cutoff date. The search engines we highlight here also use LLMs to understand the text you enter, but rather than basing their results on a fixed knowledge base, they scan the live web for up-to-date information and use AI to generate the best answer. The better ones even show you their sources so you can double-check them.

Keep in mind that, like all the generative AI tools, the search engines listed below might make mistakes, just like humans do occasionally. Read on to explore the most intriguing AI search engines we’ve come across.
