What is Preplexity?

Preplexity is an artificial intelligence (AI)-powered search and response platform launched in 2022, which combines the functions of an advanced search engine with a conversational chatbot. It uses state-of-the-art language models (such as GPT-4, Claude, Mistral and proprietary models) to interpret users’ questions, search for information in real time on the internet and provide direct answers, always citing the sources used.

Key features of Perplexity

• Answers with sources: Unlike traditional search engines, Perplexity provides comprehensive, contextualised answers accompanied by links to the sources consulted, allowing users to verify the information and explore the topic in greater depth246.

• Natural language processing: Uses advanced NLP techniques to understand the context and intent of questions, offering personalised and accurate answers24.

• Real-time search: Performs up-to-date web searches before responding, ensuring the latest information on news, sport, science, technology and other topics25.

• Continuous interaction: Maintains the context of previous questions within the same session, enabling more natural conversations and answers to follow-up questions24.

• Multimodality: Allows the upload of images, PDFs and other files for analysis and response generation, as well as creating AI-generated images (in the Pro version)24.

• Custom search modes: The ‘Focus’ feature allows searches to be restricted to specific websites or sources, such as Reddit, YouTube, Wolfram Alpha or academic literature24.

• Free and Pro versions: The free version already offers quick answers and access to Perplexity’s own model, whilst the Pro (paid) version unlocks more advanced models, unlimited searches, file analysis, image generation and other premium features.

How to use

You can access Perplexity via the official website (perplexity.ai), mobile apps or a browser extension. You don’t need to create an account to use the free version, which already allows unlimited questions and access to answers with sources.

Key features
