AI search engines aim to improve the traditional web search experience by leveraging AI technology to fetch answers and summarize relevant links. These engines use natural language understanding to interpret queries and provide accurate results, often with summaries of sources cited. Some notable AI search engines include Perplexity, Google AI Overviews, Arc Search, and Microsoft Bing, each offering unique features and strengths. While AI search shows promise, its reliability and trustworthiness are still concerns, and its impact on the web's foundations is being closely watched. Each engine suits a different use case, and users can choose based on their needs. As the internet's knowledge graph expands, generative AI may become a natural solution for searching it. However, without established systems in place, AI search poses potential threats to the internet's functioning and revenue models.
