That makes it a quick way to get oriented on a topic and find sources to read for a paper. The free plan covers cited answers with basic models and limited use of advanced features. Perplexity Pro costs $20/month, and verified students can get Education Pro for about $10/month, which also unlocks Learn Mode — a study mode with guided explanations, flashcards, quizzes and free-response practice.
Why students use it:
Choose Consensus when your assignment needs peer-reviewed research, especially in science, health or social science.

Many students start with Perplexity to learn the landscape, then switch to Consensus or their library databases for scholarly sources.
Cite the original papers and pages you read, not the AI tool, and open every source before citing it. Follow your course's AI policy and disclose AI use when required.
