Overall, Perplexity AI is an easy-to-use AI search tool for newbies and advanced users. It mainly uses GPT-3.5 on its basic version and cites sources in all responses. To get more personalized answers from the AI model, you can complete your AI Profile.

If you want access to Perplexity AI’s Copilot search companion, use GPT-4 for all your queries, and free access to future capabilities, you can opt for their Pro version. It costs $20 per month and $200 per year (comes with a 7-day free trial).

As previously mentioned, Copilot is an interactive AI search companion powered by GPT-4 that aims to enhance the user experience. It asks clarifying questions, runs multiple searches, and summarizes results to provide accurate, tailored responses to queries. The interactive nature of Copilot helps guide users through the search process.

Let’s look at an example. Without Copilot enabled, when you ask Perplexity “What is the single best way to lose weight”, it will do a quick search from 6 sources and answer the question like this “this is no single best way to lose weight” and provide some explanation.

Perplexity AI vs. ChatGPT

Below, we’ll compare perplexity AI with ChatGPT, the popular chatbot from OpenAI.

Functionality and Answer Quality

Directly comparing responses from Perplexity AI and ChatGPT can be considered futile since they are, in nature, tools that serve different purposes.

Perplexity AI is an AI search engine that focuses on search accuracy. It provides real-time, up-to-date results and cites sources to verify the information. Perplexity AI also utilizes Copilot’s interactive searching powered by GPT-4.

On the other hand, ChatGPT is a chatbot that specializes in natural conversation. It shines at long-form discussions, content creation, and code generation with human-like responses. 

As a search engine, Perplexity always accesses the latest information from the internet. It has a narrow and focused function as a search engine.

ChatGPT, by default, cannot access the internet, and its knowledge cutoff date is September 2021. However, the Plus version supports various plugins that expand ChatGPT’s capabilities, including accessing the internet. The plugins also enable ChatGPT to accomplish various other complex tasks, such as booking hotels.

Response Speed

Both tools generally have great response speed.

Compared to ChatGPT, Perplexity AI is slower since it first needs to search data all over the web in real time. ChatGPT excels more in giving responses stored on its pre-existing, trained data. However, when accessing the internet through a plugin, ChatGPT can be as slow as Perplexity, if not slower.


Perplexity AI’s Pro version costs $20/month or $200/year, with access to GPT-4 to all questions and an adequate number of searches using its AI companion, Copilot. You’ll also be a member of a private Discord server for customer support and information on future updates.

On the other hand, ChatGPT Plus charges $20/month for various advanced features. Besides having faster response speeds, the paid version gives you priority access, even during peak traffic. You’ll also be among the first few to access future improvements.

Perplexity AI is an innovative new AI search tool that makes finding facts and information easier. By searching the web in real-time, Perplexity AI excels at delivering reliable, up-to-date answers.

For those seeking quick access to credible data, Perplexity AI provides a powerful solution. Although still relatively new, this AI-driven search platform shows immense promise in evolving how we find and consume information online.
