What’s Perplexity AI?
Perplexity AI is a conversational search engine designed to provide direct, well-sourced answers to user queries. Instead of a list of links like traditional search engines, it combines real-time information retrieval, natural language processing, and machine learning to operate as an “answer engine,” delivering detailed responses with full source citations.
The company was founded in August 2022 in San Francisco, California, by four engineers:
- Aravind Srinivas (CEO) – Former AI researcher at OpenAI, DeepMind, and Google Brain.
- Denis Yarats (CTO) – Previously an AI research scientist at Meta.
- Johnny Ho (Chief Strategy Officer) – Former at Quora and quantitative trader at Tower Research Capital.
- Andy Konwinski (President and Board Member) – Co-founder of Databricks, a cloud-based data analytics platform.
Together, they successfully brainstormed and built a system that could retrieve and synthesize information as if an expert were answering directly.
On the business front, Perplexity AI completed multiple funding rounds that propelled it to unicorn status, with a valuation surpassing $1 billion, thanks to investments from high-profile investors, including Jeff Bezos, NVIDIA, Daniel Gross, and Stan Druckenmiller. By November 2024, a final capital raise brought the company’s estimated valuation to $9 billion, a significantly high sum that has marked its place in AI.
Also, Perplexity AI is accessible across major platforms, not only through the web but also via the official app on both Google Play and the Apple App Store, so it’s available on Android, iPhone, and iPad. This cross-platform support ensures you can take advantage of the conversational search experience wherever you go.
But what unique toolset does Perplexity AI have?
Perplexity AI’s features
Here are the most available features you’ll find as you sign in and begin using Perplexity AI:
Deep Research (autonomous, multi-step reports)
For larger questions, Deep Research executes dozens of searches, reads hundreds of sources, and synthesizes a structured report on its own. It’s designed for expert-level tasks (market scans, product research, finance/marketing analysis) and aims to save hours by handling the end-to-end search-plan–read–summarize circle.
Pro model selection (advanced reasoning options)
With Perplexity Pro, you can choose from advanced models when you need depth over speed. Current options listed in Perplexity’s help center include GPT-5, Claude 4.0 Sonnet, and Gemini 2.5 Pro (alongside Perplexity’s in-house Sonar), which you can switch between based on the task. This makes it easy to trade off raw reasoning strength, style, and latency as needed.
Source control and “Choose Sources”
Beyond generic web search, Perplexity lets you constrain or prioritize sources. Using Custom Web Sources and the Choose Sources control, you can search only specific sites, the open web, your organization’s files, or a combination—proper for compliance and reproducibility. Enterprise users can toggle Web, Org Files, Web + Org Files, or None to force answers from the desired corpus.
Image generation (create and edit)
Perplexity now supports generating and editing images directly from prompts. The Help Center describes this as a native feature; typical usage is asking for an image in the same chat you’re researching and iterating with edits. (Free users get limited generation; Pro expands access.)
Perplexity Pages (turn research into shareable content)
With Pages, you can transform a research thread into a polished, visually structured article or guide, preserving sources section-by-section. It’s handy for slide-ready briefs, docs for stakeholders, and public explainers you want to share.
Organization: threads, Spaces/Collections, sharing
Research is stored as threads that you can title and organize. Guides note the ability to group related work in Spaces/Collections, which helps when you’re building a body of research across multiple prompts and want consistent instructions or scope. Threads and Pages are shareable for collaboration.
Academic and topical focusing
Perplexity supports academic-oriented search to prioritize scholarly sources. In the product and API, the Academic mode/filter steers results toward peer-reviewed literature and reputable journals, which are helpful for citations and literature reviews. (On some plans, “Focus” on the web has evolved into “Choose Sources,” while the academic emphasis remains available.)
Finance features (market data workflows)
Perplexity offers a Finance experience that centers on research around tickers, earnings, and market updates. Recent demos highlight capabilities such as Earnings Hubs, price alerts, and automated “tasks” that assemble watchlist-style summaries, positioning Perplexity as a light research terminal for news-plus-numbers queries.
Buy with Pro & Snap to Shop
Perplexity’s shopping-focused tools extend the platform beyond research into practical e-commerce. Buy with Pro allows U.S.-based Pro subscribers to purchase eligible products directly within Perplexity, using saved billing and shipping details for a one-click checkout experience. The feature also offers free shipping, aiming to make product discovery and purchase seamless.
Complementing it, Snap to Shop brings visual search to the platform. Users can take or upload a photo of an item, and Perplexity will locate similar products online, complete with purchasing options. This works much like Google Lens but is integrated directly into Perplexity’s interface. Together, these tools position Perplexity as an “answer engine” and a personal shopping assistant for Pro users in the U.S.
Note: Perplexity has stated that both tools are planned for international expansion in the future, though no specific rollout timeline has been confirmed.
Always-visible citations and real-time web
A consistent differentiator is the always-visible citations attached to each claim, paired with real-time web retrieval. You can expand the footnotes, jump to sources, and keep asking clarifying or comparative follow-ups without losing the link to where facts came from. This transparency is central to Perplexity’s “answer engine” approach.
So, Perplexity combines an answer-first interface with deep-dive automation (Deep Research), model choice for more challenging problems, controllable source scopes (web, specific sites, or internal files), image generation, Pages for publishing, and finance-oriented views. It also makes verification easy via inline citations tied to live web results.
How to sign up on Perplexity AI
Getting started with Perplexity AI using the web version or mobile app is quick and straightforward.
If you’re signing up on a browser, open your preferred search engine and type “Perplexity AI.” Click on the official link (usually the first result), and you’ll be taken directly to the Perplexity AI interface. On the home screen, you’ll see a sign-in or sign-up box—usually at the right end of the screen. You can choose to create an account using an Apple ID, a Google account, or an email address. Selecting the Google option lets you connect instantly (often without manually typing your email), making the process nearly instant.
For mobile users, simply download the Perplexity AI app from the Google Play Store (for Android) or the Apple App Store (for iOS). Once installed, open the app and follow the same sign-up process.
In either case, once you’ve chosen your sign-in method, you’ll be directed straight into the interface, ready to start searching or asking questions immediately. No lengthy verification steps are required, making Perplexity AI one of the fastest AI tools to access.

Testing Perplexity AI vs Grok AI on real tasks
Here’s what I discovered when I used the same prompts on both systems.
- Real-time information accuracy test
My Prompt: “Summarize the three most significant global news events that occurred in the last 48 hours, including exact dates, main stakeholders, verified sources, and measurable impact (economic, political, or social). Use only credible sources from major news outlets or official government releases, and provide inline citations with links. Keep your answer under 300 words and structured into three short sections (one per event).”
Perplexity AI’s performance:
Perplexity delivered three current events from August 12-13, 2025: the Russia-Ukraine conflict with Trump’s Alaska summit, Canadian wildfires, and Air Canada flight cancellations. The response was impressively fast and well-structured.
What stood out was the source diversity. I could see citations from CNN, Institute for the Study of War, YouTube, and Global News. Each event included specific dates, stakeholder names (Trump, Zelensky, Putin), and measurable impacts like “over 20,000 people evacuated” and “over 10,000 employees” affected by the labor dispute.
The platform handled the 300-word limit perfectly and organized everything into the three requested sections. The sources were clickable and led to legitimate news outlets. However, I noticed the writing felt somewhat mechanical – factual but lacking natural flow.
Perplexity AI’s score on real-time information accuracy – 9/10
Grok AI’s performance:
Grok provided three current events: Ukraine Diplomacy Escalation (August 13, 2025), Gaza Strikes Intensify (August 13, 2025), and Russia-Belarus Military Drills (August 12-13, 2025). The response was notably fast, completing in just 1 minute 17 seconds.
What impressed me was the detail level. Grok included specific quotes like “… told the U.S. president… that Putin is bluffing” and precise casualty numbers from Gaza. Each event included clear stakeholder identification and measurable impacts like “Over 100 deaths” and “heightened regional tensions.”
However, I noticed Grok relied heavily on X-post as a source without showing the same source diversity that Perplexity demonstrated. The writing was more natural and conversational compared to Perplexity’s mechanical tone.
Grok AI’s score on real-time information accuracy – 8/10
- Research capabilities test
My Prompt: “Provide a concise but academically rigorous literature review of peer-reviewed studies (published 2018–2025) on the effectiveness of cognitive behavioral therapy (CBT) for treating adolescent depression. Summarize key findings, methodologies, sample sizes, and limitations for at least five studies. Use APA in-text citations and end with a proper APA-style reference list.”
Perplexity AI’s performance:
This is where Perplexity truly impressed me. The platform delivered exactly five studies as requested, all within the specified timeframe. Each study summary included methodologies (randomized controlled trials, systematic reviews), specific sample sizes (57 adolescents, 409 randomized trials), and apparent limitations.
What impressed me most was the synthesis quality. Instead of just listing studies, Perplexity connected findings across research, noting patterns like “medium to large effects on symptom reduction” and highlighting gaps like “limited long-term follow-up data.”
Perplexity AI’s score on research capabilities – 10/10
Grok AI’s performance:
Grok delivered an impressively comprehensive literature review, completing the task in just 3 minutes and 13 seconds. The platform provided exactly five studies as requested, all within the 2018-2025 timeframe, with proper APA formatting throughout.
Each study summary included detailed methodologies (meta-regression analysis, network meta-analysis, Bayesian approaches), specific sample sizes (4,335 participants, 2,230 participants), and clear limitations. The DOI links were formatted correctly, and the reference list followed APA standards perfectly.
What stood out was Grok’s ability to synthesize findings across studies, noting patterns like “moderate effectiveness for adolescent depression, especially in combination therapies.” The academic rigor matched Perplexity’s quality while maintaining better readability.
Grok AI’s score on research capabilities – 10/10
- Mathematics test
My Prompt: “A company’s revenue grows 12% per year for 5 years, starting from $250,000. Calculate the final revenue using compound growth.”
Perplexity AI’s performance:
The mathematical approach was textbook perfect. Perplexity clearly stated the compound interest formula, identified each variable, and showed every calculation step. The progression from $250,000 × (1.12)^5 to the final answer of $440,575 was easy to follow.
However, the response felt very academic and formal. While mathematically accurate, it lacked the conversational tone that might help someone actually understand compound growth in practical terms.
Perplexity AI’s score on the Mathematics test – 8/10
Grok AI’s performance:
Grok provided a thorough mathematical solution, completing the compound growth calculation in 12 seconds. The platform showed the complete formula, identified each variable clearly, and demonstrated every calculation step from (1.12)¹ through (1.12)⁵.
The step-by-step breakdown was excellent for learning: showing each power calculation (1.12² = 1.2544, 1.12³ = 1.404928, etc.) before arriving at the final answer of $440,585.42. The presentation was clear, and the rounding was appropriate for currency.
While mathematically perfect, the approach was very systematic and educational rather than conversational, similar to Perplexity’s academic style.
Grok AI’s score on the Mathematics test – 9/10
- Creative tasks test
My Prompt: “Write a 300-word short script in the style of Ernest Hemingway, set in post-war Paris, following a disillusioned journalist who meets a stranger at a café. Use minimalist prose, subtle dialogue, and vivid sensory details. End with an ambiguous emotional resolution.”
Perplexity AI’s performance:
The creative writing revealed Perplexity’s biggest weakness. While the platform delivered exactly 300 words and captured some Hemingway elements like sparse dialogue and a post-war Paris setting, the writing felt stiff and artificial.
The dialogue followed the minimalist requirement but lacked the subtle emotional undercurrents that make Hemingway’s style compelling. Phrases like “stitched together by ghosts” felt forced rather than naturally poetic. The sensory details were present but mechanical in “soft clatter of spoons,” “rain-streaked windows.”
The story structure worked—a journalist meets a stranger, and they share a moment of connection over loss—but the execution felt like an AI trying to imitate human creativity rather than actually being creative.
Perplexity AI’s score on the Creative tasks – 5/10
Grok AI’s performance:
This is where Grok truly excelled. The platform delivered a compelling 300-word Hemingway-style script in just 6 seconds – remarkably fast compared to other tasks.
The writing captured authentic Hemingway elements: sparse dialogue (“You’re American,” “Used to write for the papers. Now, nothing.”), vivid sensory details (“wet stone and black coffee,” “cigarette smoke and the faint scent of bread”), and that characteristic emotional restraint.
Grok AI’s score on creative tasks – 9/10
- Coding assistant test
My Prompt: “Write a Python function that takes a list of integers and returns a new list containing only the prime numbers, sorted in ascending order. Include clear inline comments explaining each step. After writing the function, provide three example test cases with expected outputs, and briefly explain the time complexity of your solution.”
Perplexity AI’s performance:
Perplexity delivered a comprehensive solution with two functions: is_prime() for checking primality and filter_primes() for the main task. The code was clean and well-commented, explaining each step from basic edge cases to the optimization logic.
The prime-checking algorithm was efficient, using square root optimization to quickly eliminate even numbers. The list comprehension approach for filtering was Pythonic and elegant. Most importantly, Perplexity provided all three requested test cases with expected outputs and a detailed time complexity explanation with proper mathematical notation (O(√n), O(m × √N), O(k log k)).
The response was complete and professionally structured, covering every aspect of the prompt requirements.
Perplexity AI’s score on coding Assistant – 10/10
Grok AI’s performance:
Grok delivered a complete Python solution in 15 seconds, providing both the is_prime() helper function and the get_primes() main function. The code was clean, well-commented, and used efficient algorithms with square root optimization.
The code structure was Pythonic, and the comments were genuinely helpful without being verbose. The test cases covered edge cases well, including negative numbers and empty results.
Grok AI’s score on coding assistant – 9/10
Based on these tests, I learned that Perplexity AI has superior speed without delivering mediocre quality(except in creative writing). Grok AI also demonstrated notable strengths in creative tasks and comprehensive answers.

However, while Perplexity AI can reference official legal documents and credible news sources, it is not a substitute for professional legal advice. Information may require verification against the latest state legislation or court decisions, as laws can change rapidly. Additionally, some state-specific details might be behind paywalled databases or not fully accessible through the AI’s available sources.
Financial analysts and compliance officers
Financial analysts and compliance officers require speed, accuracy, and verifiable sourcing. Perplexity AI delivers this by combining live market data with authoritative financial news and regulatory filings.
