Perplexity AI
Most PopularWhat is Perplexity AI?
AI-powered answer engine with real-time web search. Provides cited, sourced answers and tracks current events.
Perplexity AI is an answer engine that searches the live web and returns a synthesized, cited answer instead of a list of links. It offers Focus modes for narrowing searches to academic papers, Reddit, or specific sources, Spaces for organizing research by topic, and Deep Research for autonomous multi-step investigation. Its Comet browser adds agentic browsing features (and, as of March 2026, is free to use across major platforms).
What are Perplexity AI's key features?
Cited, sourced answers
Every answer links back to the web pages it was drawn from, so you can verify claims instead of taking the model's word for it.
Focus modes
Narrow a search to Academic papers, Reddit, YouTube, News, or Wolfram Alpha instead of the open web.
Deep Research
Runs an autonomous multi-step research process across many sources and compiles the findings into a structured report.
Spaces
Organize chats, uploaded files, and saved answers by project or topic instead of losing them in a flat chat history.
Comet browser
Perplexity's own browser with built-in agentic search, voice mode, and Deep Research, free to download on Windows, macOS, iOS, and Android.
Model selection on Pro
Choose between multiple underlying models (including GPT and Claude families) depending on the task.
Real-time information
Pulls current web results rather than relying only on a fixed training cutoff, useful for news and fast-moving topics.

What can you use Perplexity AI for?
How much does Perplexity AI cost?
Perplexity's Free plan is permanent but limited (recent guides cite about 3 Pro Searches a day and 1 Deep Research query a month). Pro is $20 a month, or about $17 a month on annual billing ($200 a year), Max is $200 a month ($2,000 a year), and Enterprise Pro is about $40 per seat per month. Students and educators can get Pro for about $10 a month. Perplexity's own page was hard to read in automated checks, so confirm the monthly price at checkout. Prices checked late October 2026.

Best Perplexity AI alternatives
ChatGPT
A better fit for open-ended creative writing, coding, or long conversational tasks rather than sourced research answers.
Gemini
Better if you want the research tied directly into Google Docs and the rest of Workspace.
Claude
Stronger for deep analysis of documents you upload yourself rather than live web research.
You.com
A comparable cited-search alternative worth checking for its own free-tier limits.
Is Perplexity AI worth it?
What Perplexity does better than almost anything else is get you a trustworthy, sourced answer to a factual question fast -- the citations are the whole point, and Deep Research handles genuinely time-consuming research tasks well. It's the wrong tool if what you actually need is a long creative writing partner, an image generator, or a coding assistant; Perplexity is built around search and synthesis, not open-ended generation, so ChatGPT or Claude will serve those use cases better.

Frequently Asked Questions
Is Perplexity free to use?
Yes. The free tier includes unlimited quick searches, a limited number of Pro Searches per day, all Focus modes, Spaces, and voice search, with no account required to try basic search.
What is Comet, and is it free?
Comet is Perplexity's own web browser with built-in agentic search and Deep Research. As of March 2026, Perplexity removed the paywall, so Comet is free to download and use on Windows, macOS, iOS, and Android.
How does Perplexity compare to ChatGPT for research?
Perplexity is purpose-built for cited, source-backed answers and real-time web search; ChatGPT is a more general-purpose assistant with a larger app ecosystem but less emphasis on visible sourcing by default.
Does Perplexity keep my search history private?
Perplexity's data retention and privacy settings are configurable in your account -- review the current privacy policy and account settings directly, since practices can change.
Can Perplexity generate images?
Yes, on the Pro plan and above, Perplexity includes image generation as well as video generation, though this is a secondary feature compared to its core search function.
What are Perplexity Spaces?
Spaces let you group related chats, uploaded files, and saved answers by topic or project, with custom instructions that apply to everything inside that Space.
