How It Works

When a user submits a query, Perplexity combines large language models (LLMs) with real-time web search to find, read, and summarise information from multiple sources.
It then generates a natural-language answer and provides citations to the original references.
Pro users can also upload files (PDF, CSV, images, audio) for direct analysis.
The platform supports continuous conversation, allowing follow-up questions to refine or deepen research.

Perplexity offers multiple modes:

• Regular Search / Answer Mode – quick summarised results
• Deep Research – performs multi-step searches and builds a structured report
• Model Selector – choose between AI models in the Pro version
