What is Perplexity AI? A complete guide to features, pricing, and use cases

Perplexity AI is an AI answer engine: you ask a question in plain language and get a concise, conversational response drawn from a real-time search of the web, with the sources that informed it cited inline. Instead of a page of links to sift through, you get a synthesized answer you can read, verify, and follow up on. For researchers, students, and anyone who needs current, trustworthy information fast, it works differently from both traditional search and general-purpose AI assistants like ChatGPT.

This guide covers what Perplexity AI is, how it works, what it costs, and how it compares to ChatGPT.

If you're already using Perplexity and want to do more with it, we'll also show you how IFTTT connects Perplexity to the rest of your workflow. IFTTT is an automation platform that connects over 1000 apps and services. Instead of manually copying Perplexity answers into notes or sharing results with your team, you build the connection once and it runs automatically.

What is Perplexity AI?

Perplexity AI is an AI answer engine that combines the reach of a web search with the conversational output of a large language model. You type a question, in plain language, the way you'd actually phrase it, and Perplexity searches the web in real time, synthesizes what it finds, and returns a concise, readable answer with inline citations linking back to the sources it drew from.

Founded in 2022 by Aravind Srinivas, Denis Yarats, Johnny Ho, and Andy Konwinski, several of whom previously worked at OpenAI and Google, Perplexity has grown rapidly into one of the leading AI search products. It's used by millions of people worldwide for research, fact-checking, learning, and staying current on fast-moving topics where outdated training data would give a wrong answer.

What does Perplexity AI do?

The core of what Perplexity does is answer questions, but the way it answers them is what sets it apart from traditional search and from general-purpose AI assistants like ChatGPT.

Real-time web search means every Perplexity answer is grounded in current information. Unlike AI assistants trained on a fixed dataset, Perplexity queries the web live for every response, so you're getting answers based on what's actually on the internet right now rather than what the model learned months ago.

Source citations appear inline in every answer. Perplexity shows you exactly which sources it used to construct its response, and you can click through to read them directly. This makes it possible to verify claims, read further, and trust the output in a way that's harder with AI systems that don't show their work.

Follow-up questions allow you to go deeper without starting over. After an initial answer, Perplexity suggests related questions and lets you continue the conversation with follow-ups that build on what it already knows about your query, closer to a research session than a single search.

Pro Search is Perplexity's more powerful search mode, available on the Pro plan, which asks clarifying questions before searching, performs more searches per query, and produces longer, more detailed responses for complex research tasks.

Focus modes let you direct Perplexity's search to specific sources: the general web, academic papers, YouTube videos, Reddit, or news, so the answers are drawn from the right type of content for what you're researching.

How does Perplexity AI work?

When you submit a question, Perplexity runs a set of web searches in real time, identifies the most relevant sources, and uses a large language model to synthesize those sources into a single coherent answer. The citations in the response link directly to the underlying web pages so you can check the reasoning and explore the sources yourself.

Perplexity runs multiple AI models under the hood depending on which mode you're using. The default model handles most questions well. Pro Search uses more powerful models, including access to GPT-4o, Claude, and Perplexity's own models on the Pro plan, and performs additional search iterations to produce higher-quality answers for complex queries.

The product is available on the web at perplexity.ai, on iOS and Android, and via API for developers who want to build Perplexity-powered search into their own products. It's also the foundation of IFTTT applets that use Perplexity as a query step inside automated workflows.

Is Perplexity AI free? What is Perplexity Pro?

Yes, Perplexity has a free plan that covers the core product. You get unlimited standard searches, up to 5 Pro Searches per day, and access to Perplexity's standard AI model. For casual research and everyday questions, the free plan is genuinely useful.

Perplexity Pro costs $20/month (or $200/year) and removes the limits on Pro Search, adds image generation, document and file upload for analysis, access to multiple premium AI models (GPT-4o, Claude Sonnet, and others), and API credits each month. It's designed for people who use Perplexity heavily, for work, research, or as a daily driver in place of traditional search.

Enterprise plans are available for organizations and teams, with additional security, administrative controls, and volume pricing.

Perplexity AI vs. ChatGPT: what's the difference?

Perplexity and ChatGPT are both AI tools that answer questions in conversational language, but they're optimized for different things. Here's how they compare:

Bottom line: Perplexity is the better tool when you need a current, sourced answer to a factual question, research, fact-checking, staying up to date on fast-moving topics. ChatGPT is more powerful for open-ended tasks: writing, coding, reasoning through complex problems, and use cases where web currency and citations matter less than depth of response. Both tools have IFTTT integration, so you can automate workflows with either one, or both, depending on what you're doing.

What are Perplexity AI's limitations?

Perplexity is built for answering questions grounded in what's currently on the web, which means it's less suited to tasks where current web content isn't the right source. Open-ended creative writing, complex code generation, long-form document drafting, and reasoning tasks that don't have a factual web-based answer are better handled by general-purpose assistants.

The quality of Perplexity's answers depends on the quality of what's indexed on the web. For niche, highly technical, or recently published topics with limited online coverage, answers may be shallow, incomplete, or draw on lower-quality sources. The inline citations help you catch this, but it requires reading the sources rather than trusting the synthesis at face value. Pro Search, the more powerful, multi-step search mode, is limited to 5 queries per day on the free plan. For heavy researchers, this ceiling is reached quickly, and the jump to the Pro plan is a meaningful cost increase even if the rest of the free product is sufficient.

Perplexity doesn't retain memory between separate conversations by default. Each new session starts fresh. If you're doing ongoing research across multiple sessions, you'll need to re-establish context or save your previous threads manually, which is one reason the IFTTT integrations for saving and logging answers become especially useful.

Finally, Perplexity's focus on answering questions means it's not trying to be a general-purpose AI assistant. Tasks like writing long documents, generating images (outside of Pro), handling complex spreadsheets, or providing step-by-step coding assistance are outside its primary strength.

How IFTTT works with Perplexity

Perplexity's IFTTT integration works differently from most services. Rather than triggering on events or executing actions, Perplexity operates as a query step, a Pro+ feature that sits in the middle of an applet. Something else starts the workflow (a button press, a location event, a calendar entry, a camera scan), Perplexity answers a question in response, and the result gets routed somewhere useful: a Google Doc, a spreadsheet, a Slack channel, or your phone.

This makes Perplexity uniquely powerful in IFTTT. It's not just a destination for data, it's an intelligent layer that transforms a trigger into a researched, sourced answer before that answer goes anywhere you need it.

IFTTT's Perplexity integration has two Pro+ queries: Ask Perplexity (which returns a conversational, web-grounded answer with cited sources) and Search the web (which returns top-ranked web results with titles, links, and snippets).

Save Perplexity answers to your notes automatically

Set up a workflow once and every answer you ask through IFTTT gets saved to Google Docs or Evernote automatically. Useful for anyone who wants to build a searchable archive of research without manually copying answers out of Perplexity.
