About Perplexity AI
Perplexity AI is an American privately held software company that offers an AI-powered answer engine, distinguishing itself from traditional search engines by providing direct, synthesized responses to user queries with cited sources. The platform leverages large language models and real-time web search capabilities to deliver concise, well-sourced answers. A free public version is available, and a paid Pro subscription offers access to more advanced language models and additional features. Perplexity AI aims to be a comprehensive knowledge hub where users can explore and learn effortlessly, emphasizing source transparency and direct answers over listed search results.
In March 2026, Perplexity AI launched Perplexity Health, marking its entry into the consumer health AI market. This specialized offering within its app allows users to connect health data providers, input personal medical information, and access specialized AI agents in a secure and private environment. Perplexity Health aims to unify fragmented health data from sources like electronic health records, wearables (via Terra API), and Apple Health, enabling AI agents to provide personalized answers to health queries. The company has also established the Perplexity Health Advisory Board, composed of physicians, researchers, and health technology leaders, to guide product decisions, content quality, and clinical safeguards in line with evidence-based medicine. For physicians, Perplexity Health offers tools for literature review acceleration, clinical trial landscape mapping, KOL identification, grant proposal drafting, regulatory change monitoring, and competitive pipeline analysis. It is designed to support clinical workflows by providing real-time, verifiable information and aims to streamline everyday tasks from clinical guidelines to patient education.

What Physicians Need to Know
Perplexity AI can be a valuable tool for physicians due to its emphasis on accuracy, real-time information, and cited sources. It can assist with medical literature searches, providing source-backed summaries and supporting clinical decision-making. Physicians can use it to quickly access current medical information, research specific claims, and get direct answers to complex questions, with the ability to verify information through provided citations. Perplexity AI is also becoming a significant source for healthcare recommendations, and practices can improve their visibility by ensuring they are listed on directories Perplexity pulls from, such as Yelp, Zocdoc, Healthgrades, and Vitals, and by structuring website content for AI extraction and citation. Perplexity has partnered with Wiley to search healthcare content and provide links to original, trusted sources, ensuring that health queries surface the same citations a physician or nurse would access.
Perplexity AI offers integrations to connect with various applications and automate workflows. It can be integrated with tools like Make (formerly Integromat) and Zapier to query live internet data, extract citations, and feed curated answers into databases. The Perplexity API Platform allows businesses to integrate AI for accurate answers and to automate complex work, routing tasks across multiple frontier models. Additionally, Perplexity Computer is an agentic tool that can execute complex workflows, operating software interfaces like a human co-worker, performing web research, document generation, data processing, or API calls to connected services.
