Exa is a modern AI search engine designed to provide rapid search capabilities, offering tools such as SERP API, website crawler tools, and a deep research API to enhance applications with web search AI. The introduction of Exa Fast marks it as the fastest search API with a p50 latency below 425ms, surpassing other tools like Brave and Google Serp by over 30% in speed. This speed is crucial for AI systems which require low-latency searches to integrate efficiently with language models and agentic workflows, making it particularly beneficial for AI products sensitive to latency, such as AI voice companions. Unlike other search APIs that often wrap around Google, Exa has developed its own search engine from scratch, allowing complete control over the search process and optimization for reduced latency. As AI technology evolves towards faster autonomous agents, Exa aims to provide search capabilities that can meet the demands of these advancements, supporting a future where AI systems are powered by precise and current world knowledge.
