What is Perplexity: Explained
Perplexity is an AI-powered search engine and chatbot, founded in 2022 by Aravind Srinivas, Denis Yarats, and Andy Konwinski. Its first tool, Perplexity Ask, launched the same year and was later rebranded as Perplexity in February 2023, accompanied by a Chrome extension.
The platform experienced rapid growth, reaching two million users by March 2023 and nearly fifteen million monthly users by October 2024, reflecting its global popularity. Unlike Google, Perplexity doesn’t just provide links—it delivers summarized answers with references, drawing from live internet data.
Powered by OpenAI’s GPT-5, it can handle complex queries and provide up-to-date information without a fixed knowledge cutoff. Recent additions include Internal Knowledge Search for personal files and Spaces, a feature for saving and sharing research. In November 2024, Perplexity introduced sponsored questions and integrated paid media.
It also launched a shopping tool, allowing users to research and purchase products directly, a feature later mirrored by ChatGPT Search. The latest version, Perplexity 2.250731.0 (August 2025), introduces GPT-5 enhancements, faster responses, bug fixes, and new capabilities, including video generation with inline playback.

Perplexity and Controversies
Perplexity has faced copyright-related disputes. In 2024, Forbes and other media outlets, including The New York Times and Condé Nast, sent legal notices citing data misuse. Currently, NewsCorp is pursuing a lawsuit for large-scale copyright infringement. These cases highlight ongoing concerns about AI and intellectual property rights.
Perplexity’s Future Plans
Perplexity is continuously updated with new features. Recent additions include booking tables on OpenTable and price alerts for products. Future updates may focus on personalization, creative tools, and expanding global accessibility. Its rapid growth suggests continued improvement and innovation in AI-powered search.
Perplexity Limitations
Despite its power, Perplexity has some drawbacks that users should be aware of:
Dependence on Web Content Quality
Perplexity sources data directly from the internet. If online content is outdated, biased, or incorrect, its answers may reflect the same issues. It cannot generate new facts beyond the available sources, so the reliability of the answer depends entirely on the quality of the web content.
Limited Creativity Compared to ChatGPT
Unlike generative AI tools like ChatGPT, Perplexity focuses on factual accuracy. It is not suitable for creative writing, storytelling, jokes, or imaginative brainstorming. It is designed for research, learning, and clarity of knowledge rather than creative content.
3. Lack of Deep Personalization
Perplexity does not retain long-term memory of past searches. Each session is independent, making it less personalized than AI tools with persistent memory or adaptive learning.
4. Confusion with Complex or Vague Queries
It may struggle with multi-layered or ambiguous questions. Broad or unclear queries can lead to oversimplified answers. Direct and specific questions work best; complex research may require rephrasing multiple times.
5. Pro Features Locked Behind Subscription
Many advanced capabilities—such as unlimited file uploads, image analysis, video generation, and large-scale advanced searches—are exclusive to the paid Pro plan. Free users may find these limitations restrictive.
6. No Offline Access
Perplexity requires a live internet connection to function. It does not function offline or as a local knowledge database, which limits its use in areas with poor connectivity.
Perplexity and Controversies
Perplexity has faced legal and copyright challenges. In 2024, Forbes accused it of data misuse, while The New York Times and Condé Nast issued legal notices. Currently, NewsCorp is suing Perplexity for large-scale copyright infringement. These cases highlight ongoing concerns regarding AI use of media content and intellectual property rights.
Future Plans
Perplexity is actively evolving. Recent updates include OpenTable booking integration and product price alerts, demonstrating continuous improvement in performance and usability. Developers are likely to introduce more personalization features and creative tools in future updates. Its rapid growth and frequent updates suggest that it will continue to enhance functionality and expand its global reach.
