Perplexity AI
AI-powered answer engine that searches the web and your own files in real time and returns cited, conversational responses.
About
Perplexity AI combines a large language model with live web search to give direct answers instead of a list of links. Every response includes source citations so you can verify the information, and you can ask follow-up questions in the same thread to dig deeper. It supports file uploads, image analysis, and lets Pro subscribers choose from multiple frontier models including GPT, Claude, and Gemini. The free tier covers everyday queries with a daily limit on advanced searches, while the Pro plan at $20 per month unlocks unlimited searches, file uploads, and model selection. Enterprise plans are also available for teams.
