Perplexity
AI-powered search engine that answers questions with cited sources drawn from the live web, replacing traditional link lists with direct, referenced responses.
About
Perplexity combines web search with large language models to give you a direct answer rather than a list of links to sift through. Every response includes citations so you can verify the sources, and you can ask follow-up questions to dig deeper without starting over. The free plan covers unlimited quick searches and a small daily allowance of more powerful Pro searches. The Pro plan at $20 per month adds unlimited advanced searches and the ability to switch between models from OpenAI, Anthropic, Google, and others. Enterprise plans with compliance features are available for teams.
