What is Perplexity AI?

Perplexity AI functions as an AI-powered search engine that delivers summarized responses with direct source references, allowing users to verify information or explore topics further. Unlike traditional chatbots, it supports follow-up questions and specialized research environments, including a Computer mode for completing multistep tasks. The platform offers multiple tiers: Standard Search for quick answers on the free plan, Pro Search for tailored responses on paid plans, and Deep Research for in-depth analysis using extensive sources.

The platform includes interactive learning tools like Learn step by step, which acts as a tutor by using questions and exercises to guide users through topics, such as preparing for a Spanish exam. Users can also select from multiple AI models via Model Council, which aggregates responses from different models and highlights areas of agreement or disagreement. These features position Perplexity as both a research assistant and an educational resource.

Perplexity Computer is an AI agent designed to automate multistep tasks, such as creating financial spreadsheets or workbooks, saving users time by reducing manual setup and troubleshooting. It operates within a library of user-created files and supported apps like Asana, Google Drive, and Notion, enabling seamless task execution without manual data transfers.

The platform provides focused research environments through its Apps menu, including Finance for market tracking, Personal CFO for portfolio monitoring, Health for health record integration, Academic for scholarly searches, and Patents for patent research. These tools cater to specific professional and personal needs, expanding Perplexity’s utility beyond basic search.
