Perplexity Pro is an AI-powered search engine that answers questions with cited sources. ChatGPT Plus is a full-featured AI assistant. They overlap in some use cases — both can answer research questions — but they're built for fundamentally different workflows. If you want cited, up-to-date answers quickly, Perplexity. If you want a flexible AI assistant that writes, codes, and analyzes documents, ChatGPT Plus.
ChatGPT Plus
Perplexity Pro wins for research and fact-finding with citations. ChatGPT Plus wins as a general AI assistant for writing, coding, and analysis.

Real-Time Search and Citations
Perplexity's core value is answering questions with real-time web sources and inline citations. You ask a research question; Perplexity searches the web, synthesizes the answer, and shows you the sources. For fact-checking, research, and 'what's the current status of X' queries, it's faster and more trustworthy than ChatGPT's browsing.
ChatGPT Plus has browsing (via Bing), but web search in ChatGPT is clearly secondary to its generative capabilities. Perplexity built the entire product around search-grounded answers.
Model Access
Perplexity Pro gives you access to GPT-4o, Claude 3.5 Sonnet, Gemini 1.5 Pro, and Perplexity's own models — all in one subscription. You can pick the model you want for each query. That's a remarkable value if you're already paying for ChatGPT Plus separately.
ChatGPT Plus gives you GPT-4o (with rate limits during peak hours) and GPT-4o mini. It's one model family, optimized deeply. If you want OpenAI's models at full quality, ChatGPT Plus is still the best way to access them.
Writing and Task Assistance
Perplexity can write content, but it's not optimized for long-form generation, code execution, or document creation. It's a Q&A and research tool that can draft text, not a writing assistant that can search.
ChatGPT Plus is significantly more capable for coding (with Code Interpreter), image generation (DALL-E 3), and complex multi-turn creative work. If research is 20% of your AI use and creative/coding tasks are 80%, ChatGPT Plus is the right pick.

FAQ
Does Perplexity Pro replace a ChatGPT subscription?
For research and fact-finding, Perplexity Pro may replace your ChatGPT usage. But if you use Code Interpreter, DALL-E 3, or complex writing workflows, ChatGPT Plus isn't replaceable by Perplexity.
