Felo

What Felo does: Users input queries in their native language; the engine automatically searches multilingual websites, social platforms, and academic papers, then translates and synthesizes the results into concise answers with citations. Its core strength is breaking language barriers—for example, a Chinese query can fetch Japanese and English materials and output an answer in Chinese. The free version already supports model switching (e.g., Claude Sonnet 5), custom agents, and a “Topic” feature similar to NotebookLM that allows file imports for deep analysis. Pros: ① Free to use, offering cross-language AI search without payment; ② Broad source coverage, including social content from Xiaohongshu and Twitter, suitable for Chinese-market users; ③ Enterprise edition can be deployed quickly in Japan via SB C&S distribution channels, providing end-to-end business assistance.
