Searching with LLMs has become a major alternative to Google search. We benchmarked the following AI search engines to see which one provides the most correct results:
Benchmark results
Deepseek is the leader of this benchmark, by correctly providing 57% of the data in our ground truth dataset.
Methodology
Our prompt: “List all companies that are currently manufacturing or have announced AI-specific chips/accelerators, including: 1. Their flagship AI chip models 2. Manufacturing process node (e.g., 5nm, 4nm)”
We checked if they correctly find the company, its product, and its process node. We rated them with the amount of information correctly provided, if any information was wrong or missing, we rated them 0.
Top AI Search Engines
DeepSeek Search
Deepseek search can be used together with the Deepthink (R1) mode. Since it is open-source, users can make unlimited searches with it.
Andi
Andi is a free AI answer engine, it first finds information from various sources, and then with the approval of the user, it prepares a document by using those sources. Since it is a free tool for now, it may be a good choice for users with a limited budget.
ChatGPT Search
ChatGPT Search can be used with GPT-4o, o3-mini, and o3-mini-high right now but it is not available to use with o1 or o1 mini.
Perplexity
While not an LLM itself, Perplexity uses AI models (such as DeepSeek R1) for web searches and is one of the leading AI search engines.
How do they differ from the traditional search engines?
The main differences are:
- When you search for something on Google, you see some sponsored pages at the top, and some of them are not relevant to your query. Also, the pop-ups on the pages might be time-consuming on traditional search engines.
- You can reach the results faster with AI search engines. They search many pages in seconds and provide you with only the related part of an article or blog, not the whole text.
- AI search engines do not allow users to experience reading a blog post, discovering another interesting topic on the page, and broadening their knowledge in that way. Getting faster results may help in some cases, but to learn new concepts, regular search is a better option.
- You can use the reasoning skills of the AI tools, for example:
It first gathered information about every tool and its pricing.
Then, by using this information, it calculated the total costs and compared them with each other.
Using the same prompt on Google Search will not provide direct answers. Instead, you would need to search for ‘RPA pricing,’ ‘UiPath pricing,’ ‘Automation Anywhere pricing,’ etc., and then calculate the pricing yourself.
However, in that search, ChatGPT didn’t use pricing information from the official websites of the RPA vendors. Therefore, you should be careful about trusting the information. For more reliable results, you can refine your prompt by adding phrases like ‘Only use information from official websites’. We recommend always checking the sources before trusting the provided data.
Pricing
DeepSeek and Andi are free to use.
ChatGPT Search is available in the free tier with a daily limit. Perplexity Pro Search is limited to five queries per day, while Perplexity Search is free to use.

FAQ
What is an AI search engine?
An AI answer engine uses artificial intelligence (AI) to improve the search experience and provide more accurate results.
AI search engines use natural language processing (NLP) to understand search queries and provide relevant results.
They can also learn from user behavior and adapt to provide more personalized results with their AI features, unlike a traditional browser.
The main issue is that they can provide incorrect information, and users tend to believe it without fact-checking simply because sources are listed. Therefore, finding the best search engine is important to get more accurate results.
