Understanding your question

Perplexity leverages sophisticated AI to interpret your question, ensuring it knows exactly what you’re asking.

Searching the web

It scours the internet, gathering information from authoritative sources like articles, websites, and journals. Looking for live updates of a soccer game? Perplexity can do that.
