Perplexity AI is a conversational search and answer engine founded in 2022, headquartered in San Francisco. It combines large language models with real-time web access and source citation to provide direct, verifiable answers to natural language queries — positioned between a traditional search engine and an AI chatbot. The platform serves millions of users and has expanded significantly in 2025–2026 with new product lines including Perplexity Computer, Comet (a free AI browser released March 2026), and Enterprise offerings.
Pricing as of May 2026: Free provides unlimited basic searches with source citations and approximately 5 Pro Search queries per day, but no access to advanced AI models, image generation, or premium data sources. Pro at $20/month ($200/year, ~$16.67/month) provides unlimited Pro Search, access to the latest models from OpenAI, Anthropic, and others, file uploads, image and video generation, and $5/month in Sonar API credits. Max at $200/month ($2,000/year) adds unlimited Labs and computer agent features, unlimited Deep Research, and priority access to new features. Education Pro is $10/month for verified students (via SheerID). Enterprise Pro starts at $40/user/month ($400/year) with shared Spaces, admin controls, SSO, and SOC 2 compliance. Enterprise Max at $325/user/month adds the highest model access and advanced governance features.
The Comet AI browser was released free in March 2026. Previously a $200/month PC-only subscription effectively bundled with Max, the browser now works free across iOS, Android, Windows, and Mac with agentic search, page summarization, voice mode, shopping assistance, and Deep Research built in.
The Sonar API enables developers to integrate Perplexity’s search-grounded AI into their own products, with pricing ranging from $1/million input tokens on the base Sonar model to $15/million output tokens on Sonar Pro — with web search grounding baked in, eliminating the need for a separate search integration.
Perplexity’s defining feature is real-time web access with citations in every response. Unlike general-purpose AI assistants that have a knowledge cutoff, Perplexity searches the current web for every query, making it particularly valuable for research, fact-checking, and questions about recent events.
