What Is Perplexity AI?
Perplexity AI is fundamentally different from ChatGPT or MagicSchool AI — it is an AI-powered search engine, not a content generator. Every answer Perplexity gives is grounded in real-time web sources with citations. For teachers, this makes it excellent for research tasks: quickly understanding a new curriculum topic, fact-checking a student's claim, finding current data for a science or social studies lesson, or compiling recent news for discussion. Unlike ChatGPT, Perplexity will not fabricate citations — you can click every source and verify it yourself. It is not the right tool for generating lesson plans or student materials, but it is the best AI research assistant available for free.
