TL;DR
- Perplexity AI is an AI-powered answer engine that searches the web and academic sources in real time, then gives you a concise, citation-backed answer instead of a list of links.
- This makes it fundamentally different from a chatbot like ChatGPT or Claude, which answer primarily from trained knowledge unless explicitly given web search/research tools.
- Best use case: research questions where you want a sourced, verifiable answer rather than a generated one.
Note: Anthropic’s Claude also offers a Research feature on paid plans that browses the web — see our Claude pricing guide for details on which plans include it.
