Perplexity AI
AI Search EnginesAn AI-powered next-generation search engine that searches the web in real time and generates accurate, source-cited answers.
What is Perplexity AI?
Perplexity AI is a next-generation search engine powered by AI technology. Rather than listing search result links like traditional search engines, it collects and synthesizes information from multiple web sources and delivers comprehensive, natural-language answers with cited sources. In Pro Search mode, it automatically breaks down queries into multiple sub-queries for deeper research. It can gather information from diverse sources including academic papers, news outlets, and forums like Reddit, making it particularly well-suited for research purposes. The Spaces feature lets you organize and share research findings on specific topics.
