Felo is an AI-powered search engine and research assistant that combines real-time web search with large language model reasoning to deliver comprehensive, sourced answers to complex questions. Unlike traditional search engines that return a list of links, Felo reads multiple sources and synthesizes them into a coherent, cited answer — similar to Perplexity but with a stronger focus on multilingual support and deep research workflows. It natively supports English, Japanese, Chinese, Korean, Spanish, French, German, Portuguese, and more, making it a global research tool. Felo's Deep Search mode automatically generates a multi-step research plan, searches for information at each step, and builds a structured research report with an outline, analysis, and full citations — comparable to a professional research brief. The platform also includes an AI mindmap generator that visualizes how concepts from search results connect, a note-taking system for organizing research findings, and a collections feature for managing ongoing research projects. Felo is used by researchers, students, business analysts, and professionals who need fast, reliable, sourced answers in multiple languages without language barriers limiting their access to information.
