Perplexity AI

Perplexity AI is an AI-powered answer engine that combines large language models with real-time web search to provide accurate, sourced answers to any question. Unlike traditional search engines that return links, Perplexity synthesizes information from multiple sources into comprehensive, cited answers — and unlike ChatGPT, every claim is backed by verifiable source links. It has quickly become the go-to research tool for professionals, students, and curious minds.

Key features include real-time web search with source citations for every answer, Pro Search with multi-step reasoning for complex questions, Focus modes (Academic, Writing, Math, Video, Social) for specialized searches, Collections for organizing research into shareable knowledge bases, file upload and analysis, image generation, API access for developers, and a clean interface designed for follow-up questions. Perplexity also offers Spaces for collaborative research projects.

Perplexity offers a generous free tier with unlimited quick searches and limited Pro searches daily. Perplexity Pro costs $20/month for unlimited Pro searches, access to multiple AI models (GPT-4, Claude, and more), higher file upload limits, and API credits. Enterprise plans include team workspaces, SSO, and admin controls. Perplexity has become essential for anyone who values accuracy and citations in AI-generated responses, effectively replacing Google for many research-oriented queries.
