Perplexity AI vs ChatGPT — Which AI Search is Better in 2026?
AI-powered research has split into two camps: Perplexity AI, the cited answer engine, and ChatGPT, the versatile assistant with web search. Here's when to use each.
Perplexity AI Overview
Perplexity combines real-time web search with LLM reasoning, returning answers with inline citations. Every claim links to a source, making it ideal for fact-checking and research. Pro Search handles multi-step queries, while Spaces lets you build custom knowledge bases.
ChatGPT with Web Search Overview
ChatGPT's web browsing mode can search the internet in real-time, but it's primarily an assistant — not a search engine. It synthesizes information into coherent responses but doesn't always cite sources as clearly as Perplexity.
