About Perplexity
Perplexity is an AI answer engine founded in August 2022 by Aravind Srinivas, Denis Yarats, Johnny Ho, and Andy Konwinski. Instead of returning a list of blue links, it combines real-time web search with frontier large language models to write conversational, cited answers. By late 2025 it had reached a roughly $20 billion valuation with backers including Jeff Bezos, Nvidia, and Databricks, making it one of the most prominent independent AI companies.
What it does
At its core, Perplexity is a chat box pointed at the live internet. Every answer is grounded in sources you can click through to verify, and follow-up questions stay in the same thread so you can drill deeper. It now spans general web search, finance and stocks, shopping with one-click checkout, travel, and an academic mode focused on peer-reviewed papers.
Models and Pro Search
Free users get standard answers powered by Perplexity's Sonar models. Pro subscribers ($20/month) unlock Pro Search and can pick from a rotating roster of top-tier models including GPT-5.2, Claude Sonnet 4.6, Gemini 3.1 Pro, Grok, and Sonar Pro. Pro Search runs an agentic, multi-step retrieval loop that breaks your question into sub-queries and stitches the results back together with citations.
Deep Research and Labs
Deep Research mode performs dozens of searches and reads hundreds of pages to produce long-form, structured reports with citations, useful for market analysis, due diligence, or literature reviews. Labs lets you generate dashboards, spreadsheets, slide decks, and small web apps directly from a prompt, with unlimited usage on the Max plan.
Comet, the AI browser
Comet is Perplexity's agentic browser, first rolled out to Max subscribers in 2025 and expanded more broadly since. It puts a Max Assistant sidebar next to whatever page you're on, so it can summarize tabs, fill out forms, compare products, draft replies in your inbox, and complete multi-step tasks across sites without you copy-pasting context.
Spaces and collaboration
Spaces (formerly Collections) let you create a working area pinned to a topic, with custom instructions, uploaded files, and a chosen model. Teams use them for internal knowledge bases, ongoing research projects, or shared client briefs that everyone can query in natural language.
Plans and pricing
The free tier covers basic answers and limited Pro Search. Perplexity Pro is $20/month and is the default for most heavy individual users. Perplexity Max, launched in mid-2025 at $200/month (or $2,000/year), targets power users with unlimited Labs, early access to Comet features, priority support, and access to top reasoning models like OpenAI's o3-pro and Claude Opus 4. Enterprise Pro adds SSO, admin controls, and data isolation for teams.
Sonar API
Developers can hit the same engine through the Sonar API, which exposes Sonar, Sonar Pro, Sonar Reasoning Pro, and Sonar Deep Research over an OpenAI-compatible chat-completions interface. It's a popular pick when you need answers that come with fresh web grounding and citations baked in, instead of building your own scraping and RAG stack.
Summary
Perplexity has grown from a clever GPT-3.5 search demo in 2022 into a full AI productivity stack — answer engine, deep research, agentic browser, Spaces, Labs, and an API. If you spend a lot of time researching, comparing, or summarizing what's happening on the live web, it's one of the most useful AI tools you can put in your daily flow.
