Details
Perplexity is an AI-powered search engine that retrieves and synthesizes information from the web in real-time, providing cited answers to user queries. In contrast, ChatGPT is a general-purpose AI assistant designed for text generation, problem-solving, and open-ended conversations. While both tools use natural language processing, their underlying architectures and use cases differ significantly. Perplexity has built its own proprietary AI models for the search-and-synthesis task, while the option to use GPT-4 or Claude is available only for Perplexity Pro subscribers. The key distinction is that Perplexity's core functionality does not rely on OpenAI or Anthropic models, despite the availability of those options. This creates confusion for some users who assume Perplexity is built on ChatGPT, when in reality, the two products serve different purposes and use distinct AI technologies.
