Key features of Perplexity.ai include:

2. AI-generated responses: The platform uses large language models to generate coherent answers based on information from various sources.
3. Real-time information: It can provide up-to-date information by accessing current online sources.
4. Source citations: Answers typically include links to the sources used, allowing users to verify information.
5. Conversational interface: Users can ask follow-up questions to refine or expand on the initial answer.
6. Multi-modal capabilities: It can handle text-based queries as well as analyze images in some cases.

Perplexity.ai represents a new wave of AI-assisted search tools that aim to make information retrieval more intuitive and efficient. However, as with any AI system, its responses may not always be perfectly accurate, and users are encouraged to verify important information.
