What is Perplexity

Perplexity is built around a simple promise: faster research with citations. It is less about being a general productivity suite and more about being a strong front end for asking, finding, comparing, and validating information. That makes it especially useful for operators, analysts, marketers, researchers, and anyone doing high-volume web-backed knowledge work.

Perplexity started by focusing on a narrower problem than most AI assistants: turning AI into a better research interface with citations and web grounding. That history still defines the product today, because even as the platform has added more models and enterprise plans, its strongest identity remains fast, sourced knowledge work rather than general AI theatre.

Core offerings

  • Search-first AI answers with source citations.
  • File, photo, audio, and video analysis features on paid plans.
  • Access to multiple premium models inside one subscription.
  • API options for search and Sonar model use.

Pricing

Perplexity offers Free at US$0 per month, Pro at US$20 per month, and Max at US$200 per month. The current credit policy gives new Pro subscribers a one-time 4,000-credit bonus that expires after 30 days, not a recurring monthly allocation. Max includes 10,000 recurring monthly credits plus a one-time 35,000-credit bonus that expires after 30 days. Enterprise Pro is US$40 per seat per month or US$400 per year, while Enterprise Max is US$325 per seat per month or US$3,250 per year. Perplexity values 100 credits at US$1 and separately publishes API pricing for search and Sonar-family model usage.

Model footprint

Perplexity’s value is not that it owns the largest number of models. It is that one subscription can expose users to several top models with a research-oriented interface. Perplexity’s own help centre currently references models such as GPT-5.2, Claude Sonnet 4.6, Gemini 3.1 Pro, and Grok 4 for Pro or Max users.

Why select Perplexity

Perplexity is a strong fit when the user experience of research matters more than raw model tinkering. It excels when teams need quick, sourced answers rather than complex automation or infrastructure-heavy deployment.

Model disclosure note

Perplexity is best understood as a research product that layers search and citations over multiple underlying model options. The accessible model list changes by subscription tier, so platform behaviour matters more than a static model sheet.
