Who it's for
- Professionals and college students who need to quickly gather evidence with sources for reports and presentations.
- People who want to fact-check information but find it tedious to open every search result one by one.
- Users looking for up-to-date information like current news, prices, or schedules. While regular chatbots do not know events after their training cutoff, Perplexity searches in real time to answer.
Drawbacks
- Pro search on the free plan has a daily limit, making it insufficient for multiple in-depth research sessions.
- Even when asked in Korean, English sources often appear first, so it is necessary to cross-check with Naver or Google search for local context.
- Although it provides sources, the AI summary may sometimes differ from the original text, so you should open the links to verify before quoting.
Getting started
- Visit the official website. You can start searching right away without logging in.
- Type your question in full sentences into the search bar. Example: "What is the student-to-teacher ratio for elementary schools in 2026?"
- Check the numbered source cards above the answer, and click them to verify critical numbers in the original text.
- Ask follow-up questions to narrow down the search while keeping context. For example, ask "What about just Seoul?"
- Creating an account saves your search history and unlocks daily Pro searches on the free plan. Installing the mobile app lets you continue the same conversations on your phone.
