About Perplexity AI
Perplexity AI is an AI-powered answer engine built by Perplexity AI, Inc. (founded August 2022), designed to search the live web and return structured, cited answers in seconds. As of early 2026, it serves 45 million monthly users and processes over 1 billion queries per month, generating $450 million in annualized recurring revenue. Unlike static chatbots that rely on frozen training data, Perplexity retrieves real-time information from indexed web pages and pairs each answer with numbered source links, making it the primary tool for research that requires verifiability. The platform runs a multi-model architecture coordinating up to 19 distinct AI models, including its proprietary Sonar engine built on top of Llama 3.3 70B with additional fine-tuning for search-relevance and factual accuracy. Sonar runs at 1,200 tokens per second on Cerebras inference infrastructure, enabling near-instant answers even for complex queries. For deeper research tasks, Pro and Max users access Deep Research mode, which autonomously visits 100 or more web pages per query, cross-references data points, flags contradictions, and generates a structured multi-section report with full citations in 2 to 5 minutes, running on Claude Opus 4.5 and 4.6 for reasoning. In 2026, Perplexity expanded from an answer engine into a full agentic platform. Perplexity Computer, launched February 25, 2026, is an autonomous AI agent that executes multi-step workflows by browsing the web, operating software, filling forms, and spawning sub-agents for parallel tasks. Model Council, launched February 5, 2026, runs a single query across three AI models simultaneously so users can compare outputs side by side. The Comet browser embeds Perplexity search into an AI-native browser with granular privacy controls and autonomous task execution for actions like booking flights and managing email. Pricing spans five tiers: Free (unlimited basic searches, 5 Pro Searches per day), Pro at $20/month (unlimited Pro Searches, image uploads, file analysis, access to advanced models), Max at $200/month (highest query limits, Perplexity Computer access), Enterprise Pro at $40/user/month (team collaboration, shared knowledge base, SSO, zero training on customer data), and Enterprise Max at $325/user/month (full feature access, HIPAA eligibility, dedicated support). The Sonar API starts at $1 per million tokens and is OpenAI-compatible. The platform is available on web, iOS, Android, and macOS. Perplexity's clearest advantage over ChatGPT is citation accuracy: in head-to-head tests, Perplexity returns more verifiable sources with fewer hallucinated URLs. Its main weakness is creative tasks and deep code debugging, where ChatGPT and Claude remain stronger. Backed by $1.72 billion across 11 funding rounds from Jeff Bezos, Nvidia, and Databricks, Perplexity reached a $22.6 billion valuation by January 2026.

Frequently Asked Questions
What is Perplexity AI and who built it?
Perplexity AI is an AI-powered answer engine founded in 2022 and headquartered in San Francisco, built to bridge traditional search engines and AI chat by returning real-time, citation-backed answers. The company has raised approximately $1.72 billion across 11+ funding rounds from investors including Jeff Bezos, Nvidia, Databricks, and IVP, including a $200 million round in June 2026 specifically for its Comet browser. Perplexity's core search model, Sonar, is built on Llama 3.3 70B, while Deep Research mode uses Claude Opus 4.5/4.6, and the platform coordinates up to 19 distinct AI models via its Model Council feature. In January 2026, Perplexity became a Wikimedia Enterprise customer, gaining structured access to Wikipedia's data. Leadership includes CTO Denis Yarats (formerly Meta AI), President Andy Konwinski (Databricks co-founder), and Chief Strategy Officer Johnny Ho.
How much does Perplexity AI cost?
Perplexity AI offers five main pricing tiers. The Free tier includes unlimited basic searches and 5 Pro Searches per day at no cost. Pro costs $20/month (or $200/year) and adds Deep Research, Model Council, and higher Pro Search limits up to 600 searches per day. Education Pro costs $10/month for verified students. Max costs $200/month (or $2,000/year) for the highest usage limits and priority access to Perplexity Computer, the agentic AI launched in February 2026. On the business side, Enterprise Pro costs $40 per user per month and Enterprise Max costs $325 per user per month, both with SOC 2 Type II, HIPAA, GDPR, and ISO 27001 compliance. The Sonar API starts at $1 per million input tokens and $1 per million output tokens for the base model, rising to $15 per million output tokens for Sonar Pro. The Comet browser itself is free on iOS, Android, Windows, and Mac, with Comet Plus at $5/month for premium publisher content.
What does Perplexity AI do that competitors don't?
Perplexity's core differentiator is that every answer returns numbered citations to live web sources, verifiable in under 10 seconds, rather than presenting unsourced generated text. Deep Research mode autonomously visits 100 or more web pages per query, cross-references data, flags contradictions, and produces a structured multi-section report in 2-5 minutes. Model Council lets users run a single query through three AI models simultaneously to compare outputs side by side, drawing from a pool of up to 19 coordinated models. Perplexity Computer, launched February 2026, is an autonomous agent that browses the web, operates software, fills forms, and spins up parallel sub-agents to complete multi-step workflows. The free Comet browser, available on iOS, Android, Windows, and Mac since October 2025, reached #3 on the US App Store within 48 hours of its iOS launch and integrates Perplexity's search and agent capabilities directly into browsing.
How does Perplexity compare to ChatGPT and Google Search?
Perplexity positions itself as an answer engine rather than a general chatbot or traditional search engine: every response includes numbered citations to live sources, which ChatGPT's default mode does not provide and which Google Search's organic results require users to click through to verify themselves. However, Perplexity's coding, debugging, and advanced mathematics capabilities are generally considered weaker than ChatGPT's GPT-5.5, which scores 88.7% on SWE-Bench Verified. Perplexity's Deep Research mode, which visits 100+ pages per query, is comparable in concept to ChatGPT's Deep Research and Gemini's research tools but is core to Perplexity's product rather than a secondary feature. On scale, Perplexity's user base (tens of millions of monthly active users depending on measurement) is far smaller than ChatGPT's 900 million weekly users or Gemini's 900 million monthly users, but Perplexity's free Comet browser gives it a distribution channel that competes directly with Chrome.
Is Perplexity AI free / does it have a free tier?
Yes, Perplexity AI has a permanent free tier that includes unlimited basic searches and 5 Pro Searches per day, each returning citation-backed answers from live web sources. Free, Pro, and Max users are opted into AI data retention by default, with a 30-day retention period and an opt-out toggle available in Account Settings. The free tier sits behind the Pro tier in the processing queue, so responses can be slower during peak hours, though Quick Search (unlimited) uses the same underlying grounding pipeline as Pro Search and is sufficient for most everyday queries. The Comet browser is also free on iOS, Android, Windows, and Mac. To unlock Deep Research, Model Council, higher Pro Search limits (up to 600/day), and Perplexity Computer, users need Pro at $20/month or Max at $200/month.
Who is Perplexity AI best for / who should avoid it?
Perplexity AI is best for research-heavy users who need verifiable, citation-backed answers quickly, such as students, analysts, and professionals doing competitive or market research, especially via Deep Research mode, which visits 100+ sources per query. Its free Comet browser is also a good fit for anyone wanting AI search and agent capabilities built directly into their browsing, without switching tabs to a separate chatbot. Developers building search-grounded applications can use the Sonar API starting at $1 per million tokens. Users whose primary need is advanced coding, debugging, or complex mathematics should consider ChatGPT or Claude instead, since Perplexity's reasoning on those tasks is generally weaker. Enterprises with strict data-residency or zero-retention requirements should use Enterprise Pro ($40/user/month) or Enterprise Max ($325/user/month), since Free, Pro, and Max consumer plans retain query data for 30 days by default.
What is Perplexity Computer and Comet, and how do they work?
Perplexity Computer, launched February 2026, is an autonomous AI agent that executes multi-step workflows: it browses the web, operates software, fills out forms, and can spin up parallel sub-agents to handle different parts of a task simultaneously, available with priority access on the Max plan ($200/month). Comet is Perplexity's AI-native web browser, which launched in July 2025 for $200/month Max subscribers and became free worldwide on iOS, Android, Windows, and Mac around October 2, 2025; it reached #3 on the US App Store within 48 hours of its iOS launch. Comet integrates Perplexity's search, citations, and agentic capabilities directly into the browsing experience, and Comet Plus, at $5/month, unlocks premium publisher content within the browser. In June 2026, Perplexity raised about $200 million specifically to expand Comet's role as what the company calls the 'front door of the agent economy.'
Does Perplexity AI train on user data and is it HIPAA/GDPR compliant?
Free, Pro, and Max consumer users are opted into AI data retention by default, with data retained for up to 30 days and an opt-out toggle available in Account Settings; Enterprise customer query data is contractually prohibited from being used for model training. Perplexity holds SOC 2 Type II, HIPAA (on Enterprise plans), GDPR, and ISO 27001 certifications. Since the EU AI Act's general-purpose AI (GPAI) obligations took effect in August 2025, Perplexity has been subject to those requirements, and enterprise customers are expected to assess domain-specific risks themselves. Organizations handling sensitive data should use Enterprise Pro or Enterprise Max, which include the HIPAA compliance and contractual no-training guarantees that consumer plans lack, plus 1-year file retention with uploads up to 1GB on Enterprise Pro.
