What is Perplexity?
Perplexity is an AI answer and research product built around retrieval. A user can enter short search-style keywords or ask a complete question; the system searches the web, organizes material from multiple sources, and keeps citations in the answer so the result does not stand as unsupported generated text.
A simple query is suited to a quick overview and follow-up questions, Pro Search performs a more guided investigation, and Research is intended for complex subjects that require repeated searching, reading, and reasoning. Longer results can become reports and be exported or turned into shareable pages, making the product less about producing more prose and more about shortening the path from discovery to a verifiable conclusion.
Projects preserve search sessions, files, instructions, connected tools, and accumulated context for an ongoing subject, allowing an individual or team to return to the same body of research. Perplexity is useful for product research, learning, travel planning, and news synthesis, but a citation does not guarantee that a source is reliable; professional decisions still require checking the original publication, date, and conflicting evidence.
Key features of Perplexity
Answer directly with citations
Perplexity searches the web and turns multiple results into a coherent answer with source links attached to relevant claims, making it easier to return to the original material.
Continue researching through follow-up questions
Follow-up questions retain the current subject and conversational context, supporting gradual narrowing, comparisons, and deeper explanation without restating the entire background.
Explore a topic with Pro Search
Pro Search performs a more extensive retrieval and synthesis process than a basic query and lets eligible users select the answering model. It fits questions that need several perspectives without a full report.
Produce a full report with Research
Research runs repeated search, reading, and reasoning steps before organizing the result into a longer sourced report that can be exported as a document or converted into a shareable page.
Maintain ongoing research in Projects
Projects place search conversations, files, custom instructions, connected tools, and accumulated context in one workspace that can support collaborators, rather than merely storing disconnected history.
Combine uploaded material and connected sources
Alongside the public web, supported Perplexity workflows can use uploaded files or authorized data connections so research can combine internal material with external information.
