ChatGPT vs Perplexity: Assistant or Search Engine?

Last checked · Based on published specs and vendor documentation. We did not test these tools ourselves.

ChatGPT and Perplexity both answer questions with AI, but they are built for different jobs. ChatGPT is a general-purpose assistant for writing, coding and everyday tasks, with a wide ecosystem of custom tools around it. Perplexity is built specifically around live web search, answering questions with cited sources front and center rather than as an afterthought.

Quick verdict

ChatGPT and Perplexity overlap at the same $20-a-month entry price, but they are not really substitutes. ChatGPT is the broader general-purpose assistant, with custom GPTs, coding tools and deeper business plans. Perplexity is a search-first tool built around fast, sourced answers to research questions. Pick based on the job: general assistant work versus quick, cited research.
