About "Felo"

What is Felo

Felo is an AI search engine that, when you enter a question, aggregates key points from multiple sources and answers with citations. Made in Japan by Sparticle Inc., it bills itself as "search, understand, and create with AI." Lately it has grown beyond search into an "AI search + creation" platform with an agent that runs research autonomously, plus mind-map and slide generation. It is Japanese-first and supports 15+ languages.

Felo searches across the web and documents for natural-language questions, organizes the key points, and answers with sources. Results can be turned into mind maps or slides (PPTX), so you can turn what you looked up into materials. It's ad-free even on the free plan, and you can save results to Topic Collections for later.

From search to creating documents and slides in one (from the official site)

Not just search—make the materials too

What sets Felo apart from ordinary search is that you can turn what you looked up straight into deliverables. It structures aggregated answers into mind maps and auto-generates PowerPoint-format slides. It also has "Deep Research (Search Agent)," which builds multiple searches automatically for cross-sectional analysis, and "Felo Agent," which carries out tasks autonomously.

How it differs from other AI search

Felo's strengths are that it is made in Japan, Japanese-first, and bundles search, material creation, and agents in one. Its handling of Japanese and depth of creation features differ from overseas AI search.

Aspect	Felo	Perplexity	NotebookLM
Focus	AI search + creation & agents	AI search (with sources)	Research limited to your own materials
Creation	Mind maps, slides	Partial	Audio overviews, notes
Japanese	Made in Japan, Japanese-first	Multilingual	Multilingual

The source-citing AI search Perplexity, the all-in-one Genspark AI, and NotebookLM (now Gemini Notebook), which answers limited to your own materials, are comparison points. If you want to research in Japanese and finish materials right away, Felo is a strong choice.
