Perplexity AI is an artificial intelligence tool that combines the strengths of a search engine and a conversational assistant. Unlike Google, which provides a list of links, Perplexity directly offers clear, synthetic and sourced answers. The user thus obtains reliable information, while having the option of exploring the original sources.
Designed to make research more intuitive, Perplexity stands out for its transparency: each answer is accompanied by precise references, making it an ideal tool for quickly checking information, delving deeper into a subject or speeding up document monitoring.
Answers sourced in real time: each answer is accompanied by clickable links to the sources used.
Conversational search: ask your questions in natural language and get complete, structured, easy-to-understand answers.
Contextual exploration: the tool suggests related questions to help you delve deeper into a subject or broaden your research.
Multi-support: available on the web, mobile and even as a browser extension to make search part of your everyday life.
Copilot mode (premium): enables more advanced searches, detailed summaries and advanced contextualization.
Real-time updates: unlike some frozen AI models, Perplexity relies on up-to-date online data.
To get the most out of Perplexity, formulate your queries in natural language as if you were asking an expert a question. For example, you could ask: “What are the benefits of teleworking for SMEs?” or “Give me a summary of the latest trends in cybersecurity in 2025”.
Next, explore the suggested sources: this not only allows you to check the reliability of the information, but also to dig deeper into the details if necessary. Use the suggestions for related questions to enrich your research and get a more complete picture of the subject.
Finally, if you need more in-depth analysis or time-consuming research, Copilot mode is particularly useful for obtaining even more detailed and personalized answers.
Perplexity’s main advantage is its ability to provide reliable, verifiable answers, making it a more transparent alternative to tools like ChatGPT. You save time by accessing clear summaries directly, while retaining the option of consulting the original sources.
Perplexity also stands out for its ease of use: a streamlined interface, instant answers and the ability to go deeper into your research effortlessly. For professionals, researchers, students or journalists, it’s a tool that combines speed, efficiency and rigor.
