Perplexity AI is a free website that does not require an account registration and does not contain any ads. Simply enter a question on the website and you can see the answer generated by Perplexity AI, as well as related web links and pictures.

- Intelligent Q&A: Perplexity AI can search for relevant information on the Internet based on the questions entered by the user, and generate concise, logical and credible answers in combination with its built-in LLM. For example, if the user asks "What is nuclear fusion", Perplexity AI will answer "Nuclear fusion is a nuclear reaction process that converts light elements into heavy elements and releases huge amounts of energy."
- Multimedia display: Perplexity AI will not only give a text answer, but also display web links and pictures that are related to the question or help understand the background and content of the question. For example, if the user asks "Who invented the telephone", Perplexity AI will answer "The telephone was first invented by Alexander Graham Bell." and display a picture of Bell and a telephone.
- Conversational Interaction: Perplexity AI can not only answer single questions, but also interact with users in a conversational way, dynamically adjusting the content and form of its answers as users ask more details or related questions. For example, if a user asks "What color do you like", Perplexity AI will answer "I like blue." If the user then asks "Why", Perplexity AI will answer "Because blue makes me feel calm and free."

Currently, Perplexity AI is completely free and open to all users without restrictions. Anyone can visit the website without registering an account or paying any fees.
However, there may be some changes in the future. According to its privacy policy, "We reserve the right to modify this policy or our terms of service, pricing or other aspects at any time."

Therefore, it is recommended that users regularly check the latest information on its website and read its relevant terms before using it.
While Perplexity AI itself is free, it relies on the OpenAI API to provide LLM services. The OpenAI API is a paid service with different fees depending on usage and model type. Currently, Perplexity AI bears all costs related to the OpenAI API and does not pass on any costs to users. However, if the OpenAI API adjusts its pricing strategy or limits its scope of use, Perplexity AI may also be affected and have to make corresponding adjustments.
