Perplexity AI Review 2025: For Japanese Researchers

Perplexity AI has changed how many Japanese researchers and professionals search for information. After 8 months of daily use, here is our honest review.

What Makes Perplexity Different

Google: An index of the web. Returns links to pages that might answer your question.

Perplexity: An AI that reads those pages and synthesizes the answer with citations.

When Perplexity is Better Than Google

  • Research questions: Synthesized answer with citations instead of 10 links to review
  • Comparisons: Structured comparison table of tools or options
  • Complex technical questions: Step-by-step with sources
  • Current events: Synthesized news analysis with citations

When Google is Better

  • You need to find a specific website
  • Local search (restaurants nearby, store hours)
  • Image search or shopping

Pro vs Free ($20/month)

The 5 Pro search/day limit becomes a problem for heavy researchers. Pro removes limits and adds file upload analysis, GPT-4o/Claude models, and API access.
