Algolia

Algolia provides search as a service: developers send their content or product catalogue to Algolia's hosted index and query it through an API that returns relevant results in milliseconds. Front-end libraries help build the search box, filters and results pages, while business teams tune ranking and merchandising from a dashboard. The range covers AI Search for keyword and semantic search, AI Recommendations, AI Browse for curated category pages, Ask AI and Generative Experiences for conversational answers grounded in indexed content, and Agent Studio for building AI agents. Analytics show what users search for and fail to find. It is used by e-commerce sites, media, marketplaces and SaaS products.
