The Search Engine Evolved
Perplexity isn't trying to be a chatbot friend; it's trying to be the ultimate answer engine. It succeeds. Instead of giving you ten blue links, it reads the links for you and synthesizes a direct answer with footnotes.
Pro Search
This feature is impressive. If you ask a vague question, Perplexity will ask clarifying questions back to narrow down exactly what you're looking for. It feels like working with a research assistant.
Model Flexibility
One of the best features of Pro is the ability to choose your underlying model. Want the reasoning of Claude 3 Opus? Or the versatility of GPT-4o? You can switch between them on the fly within the Perplexity interface.
