AI answer engine with live citations — the reasoning assistant for research and curious minds.
Perplexity is an AI answer engine — it sits between a search engine and a chatbot, answering questions in natural language while citing live web sources for every claim. That citation-first design is its whole identity: where general assistants generate fluent answers you have to trust, Perplexity shows you where each statement came from, which makes it the tool of choice for research, fact-finding, and any task where being able to verify matters.
In 2026 it runs its own Sonar model family and also lets paid users pick frontier third-party models (GPT-5.2, Opus 4.6, Gemini 3 Pro) for a given query. The Free tier is genuinely useful — 5 Deep Research queries and 3 Pro Searches per day — and is enough for casual research. Pro ($20/mo) unlocks the full Sonar family, model selection, Spaces, Pages, and Labs. Max ($200/mo) adds Perplexity Computer, which orchestrates 19 models as specialized sub-agents for complex multi-step projects.
A notable 2026 move: Perplexity's Comet browser dropped its paywall in March and is now free across iOS, Android, Windows, and Mac, with agentic search, page summarization, voice mode, and Deep Research built into the browser itself. This made Perplexity's core experience accessible to anyone without a subscription.
The honest weaknesses: as a dedicated answer engine it is narrower than ChatGPT — it is not built for long creative writing, coding workflows, or image generation. Its answers are only as good as the sources it retrieves, so on niche or fast-moving topics it can cite weak pages confidently. And the $20-to-$200 jump to Max is steep for what most researchers need. See ChatGPT vs Perplexity for the trade-off.
Who it is for: researchers, analysts, students, and anyone who wants cited, verifiable answers rather than a confident black box. Who it is not for: users who primarily want creative writing, coding help, or a single do-everything assistant — a general model serves those better.
Perplexity's core use: ask a question and get a synthesized answer with inline citations to live sources. Analysts and writers use it when they need to verify claims rather than trust a model's unsourced output, which is its decisive advantage over general chatbots.
Deep Research runs an extended, multi-source investigation into a topic and returns a structured report with citations. Even the free tier's daily allowance is enough for occasional deep dives; Pro and Max raise the limits for heavy research workflows.
With the now-free Comet browser, users get agentic search, page summarization, and Deep Research directly while browsing — asking questions about the page they are on or delegating multi-step web tasks without leaving the tab.
Perplexity offers Free ($0, 5 Deep Research + 3 Pro Searches per day), Pro ($20/mo or $200/yr, full Sonar family + selectable GPT-5.2/Opus 4.6/Gemini 3 Pro, Spaces, Pages, Labs), Max ($200/mo, adds Perplexity Computer orchestrating 19 sub-agent models), Education Pro ($10/mo for students), Enterprise Pro ($40/seat/mo), and Enterprise Max ($325/seat/mo). The Comet browser is free for everyone, with Comet Plus ($5/mo, or included with Pro/Max) unlocking premium publisher content. The pricing note: the free tier is unusually generous for casual research, and the leap to Max is only worth it for power users who need the multi-agent Computer feature.
Perplexity is an answer engine built around citations — every answer links to live web sources you can verify. ChatGPT is a general assistant that generates fluent answers you largely have to trust. For research and fact-finding Perplexity wins; for creative writing, coding, and breadth ChatGPT wins. Many people use both. See our ChatGPT vs Perplexity comparison.
No. Perplexity dropped Comet's paywall in March 2026, and it is now free on iOS, Android, Windows, and Mac with agentic search, summarization, voice mode, and Deep Research built in. Comet Plus ($5/mo, or free with Pro/Max) adds premium publisher content.
For casual research, yes — Free includes 5 Deep Research queries and 3 Pro Searches per day. Heavy researchers who hit those daily limits, or who want to select specific frontier models, will want Pro at $20/mo.
Available on the $200/mo Max tier, Perplexity Computer orchestrates 19 different AI models as specialized sub-agents. When you assign a complex project, it decomposes the task, routes each part to the best-fit model, and synthesizes the results — aimed at power users with multi-step research workloads.
On Pro and above, yes. You can run queries on Perplexity's own Sonar family or select third-party frontier models including GPT-5.2, Claude Opus 4.6, and Gemini 3 Pro, picking the best model for a given question.
