The Perplex Effect: When Search Gets Smarter Than You
Perplexity AI is a relatively new player in the AI landscape, but it has quickly gained attention for its innovative approach to search and information retrieval. Founded in 2021, the company is based in San Francisco and is led by a team of experienced entrepreneurs and AI researchers.??At the core of Perplexity AI’s technology is a large language model trained on a vast corpus of data, similar to the models used by other AI companies like OpenAI and Anthropic. However, what sets Perplexity AI apart is its unique approach to querying and retrieving information from this model.
Traditional search engines like Google rely on indexing and ranking web pages based on keywords and various ranking algorithms. Perplexity AI, on the other hand, takes a fundamentally different approach. Instead of searching for specific keywords, users can pose natural language queries to Perplexity AI’s system, which then leverages its language model to understand the intent behind the query and retrieve the most relevant information from its knowledge base.
This approach has several advantages over traditional search engines. First, it allows users to ask more complex and nuanced questions, rather than being limited to keyword searches. Second, it can provide more contextually relevant and coherent responses, as the language model can understand the relationships between different pieces of information and synthesise them into a cohesive answer.
Another key feature of Perplexity AI’s system is its ability to continuously learn and update its knowledge base. As new information becomes available on the internet or through other sources, the company’s language model can ingest and incorporate this data, ensuring that its responses are always up-to-date and accurate.
One of the standout features of Perplexity AI’s search system is its ability to engage in multi-turn conversations and ask follow-up questions to better understand the user’s intent. Unlike traditional keyword-based searches which are one-and-done, Perplexity’s language model allows for a more natural back-and-forth dialogue. If the initial query is ambiguous or lacks sufficient context, the system can prompt the user with clarifying questions to hone in on the specific information they’re seeking. This iterative process of asking follow-ups makes the experience feel more like a conversation with a knowledgeable assistant rather than simply firing off queries into a search box. The follow-on strategy allows Perplexity to provide more accurate and complete responses by developing a deeper understanding of the user’s needs through the conversational exchange.

In terms of its positioning in the AI ecosystem, Perplexity AI is part of a growing trend towards the use of large language models for various applications, including search, question answering, and content generation. While companies like Google and Microsoft have also invested heavily in language models, Perplexity AI’s focus on search and information retrieval sets it apart from some of the more established players in the field.
Despite its promising technology, Perplexity AI is still a relatively young company and faces several challenges. One of the biggest challenges is the computational cost and resources required to train and maintain large language models. Additionally, there are ongoing debates and concerns around the potential biases and ethical implications of these models, which Perplexity AI will need to address as it continues to grow.
Overall, Perplexity AI represents an exciting and innovative approach to search and information retrieval, leveraging the power of large language models to provide more contextual and nuanced responses to user queries. While it is still early days for the company, its technology has the potential to disrupt the traditional search engine landscape and pave the way for a new era of more natural and intuitive information access.
