Felo vs Perplexity — which sources does it reach for?
Felo and Perplexity are both answer engines that cite their sources. What separates them is which sources they reach for — and whether the result can be turned into a deliverable. If your research spans Japanese and English material, the distinction is practical rather than academic.

What they share
Both search the web, synthesise several sources into an answer and attach links. Unlike conventional search, you get an answer rather than a list. Unlike a plain chat model, you can trace where the answer came from.
Both are usable free. Perplexity has clearly separated free and paid tiers; Felo offers a broad free range, with upper-tier pricing to confirm on its own site.
1. Which sources get pulled in
The biggest practical difference is which sources a question in Japanese retrieves. For Japanese regulation, subsidies, statutes or industry practice, answering mainly from English-language sources misses the point entirely.
Felo is developed in Japan and is built to read across languages while answering from Japanese sources when the question is in Japanese. Perplexity is strong on English-language material, which gives it wider coverage of technical documentation and international developments.
The working rule is simple: domestic Japanese subject matter, try Felo first; international technology or products, try Perplexity first. Both show their sources, so you can judge the quality of what was retrieved yourself.
2. What happens after the search
Felo can generate slides and documents, so a research request can go from question to deliverable in one tool.
Perplexity concentrates on the quality of search and answer and assumes you take the result elsewhere. Spaces preserves context for ongoing work, but it is not a document builder.
3. Citations still have to be checked
In both tools, having a citation and being correct are different properties. Three failures recur.
- The cited page does not actually contain the statement
- The citation is a roundup article whose underlying source is out of date
- Of several citations, one is right and the others copied an error from each other
The second is constant when checking prices or specifications. Roundups do not get updated, so discontinued services and superseded prices persist indefinitely. Having found a price, open the vendor's own pricing page. This site has repeatedly found roundups listing discontinued services as current options.
4. Which to reach for
| Subject | Try first |
|---|---|
| Japanese regulation, subsidies, statutes | Felo |
| Japanese companies, services and case studies | Felo |
| International technical documentation and libraries | Perplexity |
| International product developments | Perplexity |
| Turning the research straight into a document | Felo |
| Systematic academic literature | Neither — use Elicit |
Frequently asked questions
Does this replace ordinary search?
No. Opening the relevant official page and reading it yourself remains necessary. Treat an answer engine as a fast way to find out where to look.
Which has the more generous free tier?
Felo makes a wider range of features available free. Perplexity is usable free with limits on advanced models and query volume. Check both vendor pages for current terms.
