Perplexity AI has introduced a new feature called “Deep Research” to make complex research faster and easier. This tool delivers detailed answers to expert-level queries within minutes. It uses advanced algorithms to scan vast amounts of data, saving users hours of manual work.
What is Perplexity AI’s Deep Research?
Deep Research is designed to handle complicated questions across various fields like finance, marketing, and product research. It scored 21.1% on “Humanity’s Last Exam,” outperforming many other AI models. This high performance demonstrates its ability to provide reliable and in-depth insights.
The feature is available to all users. Free accounts can access up to five queries daily, while Pro users can perform up to 500 queries each day. Currently, it works on the web, but Perplexity AI plans to extend it to iOS, Android, and Mac devices soon.
How to Use Perplexity AI’s Deep Research
Using Deep Research is simple:
- Visit Perplexity AI
- Select “Deep Research” from the search box options.
- Enter your query.
The AI will then generate a detailed research report with citations and summaries.
Rapid Growth and Major Investments
Perplexity AI has grown rapidly since its founding in 2022 by former OpenAI researcher Aravind Srinivas. In December 2024, the company secured a $500 million funding round, pushing its valuation to $9 billion. Key investors include Amazon founder Jeff Bezos and tech company Nvidia.
New Partnership with Tripadvisor
In January 2025, Perplexity partnered with Tripadvisor to enhance its hotel-related content. This collaboration helps users get detailed information, including reviews, images, and key features, sourced directly from Tripadvisor. The integration makes researching travel destinations more straightforward.
Legal Challenges and Industry Pushback
Perplexity AI’s success has not come without challenges. In October 2024, News Corp, owner of The Wall Street Journal and New York Post, filed a lawsuit against the company. The lawsuit alleges that Perplexity’s AI reproduces significant portions of copyrighted content without permission.
The company has responded by initiating revenue-sharing agreements with publishers like Time and Fortune. These deals aim to compensate publishers when their content is used, reflecting a broader trend in the AI industry to balance innovation with copyright respect.
Future Plans and Innovations
Perplexity AI continues to innovate while navigating legal challenges. It operates on a freemium model. The free version uses a custom GPT-3.5 model with browsing capabilities, while the Pro plan provides access to GPT-4 and Claude 3.5, along with API integrations and internal file searches.
The company is committed to improving information retrieval for researchers, professionals, and casual users alike. With Deep Research, finding accurate and comprehensive information has never been easier.
Perplexity AI’s ongoing partnerships and investments indicate a strong focus on growth and technological advancement. As the company expands its features across more platforms, it remains a key player in the evolving AI-powered search industry.
