Perplexity vs ChatGPT vs Gemini: 5 different challenges, who wins?


The competition among AI chatbots is no longer limited to casual conversation. As the need for quick, reliable and referenced internet research grows, 

the so-called "deep research" features of advanced bots, most notably Perplexity, ChatGPT, and Gemini, 

are transforming how information is consumed online. But when put to the test, which AI delivers the strongest performance in real-world challenges?

We have compared these three chatbots across five core challenges: research and information, general content creation, 

ease of use and interface, Integration with other tools, and cost and accessibility. Each chatbot has its advantages and disadvantages, 

hence choosing one as a winner is quite difficult. Here's how these three chatbots stand against each other.

Perplexity's deep research mode goes beyond summarising existing knowledge. It conducts iterative web searches, 

consults hundreds of sources, and rigorously refines its findings before assembling them into a detailed, referenced report. 

Citations are embedded in responses, enabling users to verify facts in real-time. Perplexity has scored as high as 93.9% on relevant factuality benchmarks and stands out for its transparent, 

reproducible research summaries. Its capability is particularly valued in academic, legal, and journalistic settings, where verifiable sourcing is paramount.
