AI search company Perplexity has launched Deep Research, a new feature designed to automate expert-level research and analysis. The tool rapidly conducts in-depth research by performing dozens of searches, reading hundreds of sources, and synthesizing findings into comprehensive reports—all within minutes. "When you ask a Deep Research question, Perplexity performs dozens of searches, reads hundreds of sources, and reasons through the material to autonomously deliver a comprehensive report," Perplexity said in a blog post on February 14.

How Deep Research Works
According to the company, Deep Research functions like a human researcher, iteratively refining its understanding of a topic. It systematically searches for relevant information, processes complex materials, and compiles clear, structured reports. Users can export findings as PDFs or Perplexity Pages for easy sharing.
"Deep Research takes question-answering to the next level by spending 2-4 minutes doing the work it would take a human expert many hours to perform," the company said.
Use Cases and Performance
"We built Deep Research to empower everyone to conduct expert-level analysis across a range of complex subject matters," Perplexity said, adding that Deep Research is designed for tasks in finance, marketing, technology, health, current affairs, and travel planning.
It achieves a 21.1 percent accuracy on Humanity's Last Exam, outperforming AI models like Gemini Thinking, o3-mini, o1, DeepSeek-R1, and many other leading models, and scores 93.9 percent on the SimpleQA benchmark. Most reports are generated in under three minutes, the company said, adding that it is working to make them even faster in the future.
