It also gives users a variety of collaborative AI models and search platforms to choose from, including OpenAI, Deepseek R1 and Claude, to name a few.

How Popular Are ChatGPT and Perplexity?

ChatGPT is the reason generative AI was first adopted into the mainstream. With nearly 60% of adults under 30 years old utilizing the platform in 2025, ChatGPT’s popularity goes without saying. It’s recognized as one of the most widely used AI platforms among US consumers, businesses, developers and marketers alike.

That doesn’t make Perplexity ‘chopped liver’ by contrast. The platform has experienced rapid growth as an AI-powered search alternative, attracting users who prioritize research, source transparency and real-time information retrieval.

How Do ChatGPT and Perplexity Work?

Here’s how ChatGPT and Perplexity work to answer users’ search queries.

How Do ChatGPT and Perplexity Work?

ChatGPT approaches personal and professional tasks through conversational interactions, multi-step reasoning and creativity and ideation using custom GPTs and handy integrations. In comparison, Perplexity offers users quick searches and real-time web access along with citation-backed answers, allowing for greater source synthesis and search-first architecture.

How Does RAG Apply to ChatGPT and Perplexity?

Retrieval-augmented generation, or RAG for short, pulls data from multiple digital sources in real-time from search results or internal documents. From there, RAG feeds said data into various AI models to give users tangible answers to their search queries.

ChatGPT uses RAG systems to search the web for data and read uploaded information (e.g., PDFs, images, spreadsheets, etc.), thereby helping its built-in large language model (LLM) to create conversational responses to user queries. Perplexity’s retrieval system works like RAG by scouring the web to research and index data, and then feed right back into an LLM to draft a response.

Similarities and Differences Between ChatGPT and Perplexity

While seemingly similar on the surface in functionality and capabilities, ChatGPT and Perplexity do have slightly different means of answering user queries.

How Are ChatGPT and Perplexity Similar and Different?

In a nutshell, both ChatGPT and Perplexity are built on LLMs and come with free and paid plans. Additionally, they offer users natural language conversations, give research assistance and provide summarization, brainstorming and much-needed support as top-tier productivity tools.

However, these platforms have some key differences in their overall features and functionality:

Key Features of ChatGPT and Perplexity

If you’re also wondering about other AI tools, such Gemini vs. ChatGPT or Copy.ai vs. ChatGPT, ChatGPT does stand out from these platforms in a number of ways. 

For example, Google Gemini and ChatGPT both have generative AI systems and LLMs with multimodal collaboration and agentic research capabilities. However, ChatGPT has been up and running far longer than Gemini’s 2023 inception and also offers far more superior logic and creativity with its GPT-4o reasoning models.

Copy.ai started out as a simple creative writing tool in 2020. From there, it morphed into the ultimate AI collaborator for digital marketers and sales departments in particular: blending research, drafting and customer relationship management (CRM) capabilities to simplify and speed up workflows across multiple platforms. 

Similarly to ChatGPT and Gemini, Copy.ai also works off an LLM, helps users brainstorm ideas and generates high-quality content. However, ChatGPT’s models are far more intuitive, whereas Copy.ai has a noticeable learning curve, which could be off-putting for some users.
