What is Perplexity AI?
Perplexity AI launched in 2022 and has grown into one of the most-used AI tools for research, effectively replacing Google for millions of knowledge workers and students. The core experience is deceptively simple: ask a question, get a synthesized answer grounded in live web sources, with citations shown next to each fact. What sets Perplexity apart from ChatGPT or Claude is the depth of real-time web integration. Every query triggers a live web search — meaning answers reflect current events, updated pricing, latest research, and anything that happened after an LLM's training cutoff. This makes Perplexity uniquely reliable for time-sensitive information. **The free tier** is genuinely useful: unlimited standard searches using Perplexity's Sonar model, plus five Pro model requests per day (GPT-4o, Claude Sonnet, or Gemini). **Pro at $20/month** unlocks unlimited Pro model searches, file uploads (PDFs, images, spreadsheets), Perplexity Pages (publish AI-generated research reports), and Spaces (private research workspaces with custom AI instructions). **Perplexity Pages** deserves special mention — it lets you generate polished, shareable research reports from any topic in seconds, complete with sections, tables, and embedded sources. Useful for content creators, analysts, and anyone who needs to share research externally. The **Perplexity API** offers sonar (web-grounded) and standard LLM endpoints in an OpenAI-compatible format, making it simple to add cited, real-time answers to any application. Pro subscribers get $5/month in API credits included. In 2026, Perplexity has expanded into voice search (iOS), shopping discovery, and enterprise features — but its core value proposition remains unchanged: the fastest, most citation-transparent AI research tool available.
