What it is and who it's for
Perplexity is an answer engine: instead of a list of links it gives you a concise answer with links to its sources, refreshed from the live web. It's for researchers, marketers and anyone who needs to get up to speed on a topic and verify facts with citations rather than digging through search results. It stands out for the combination of answer, sources and freshness, plus its deep research modes.
Key features
- Answers with inline citations and a list of sources.
- Access to the live web in real time, not just training data.
- Focus modes (academic, web and others) and domain-scoped focus.
- Deep Research / Pro Search — multi-step breakdowns of complex topics.
- File and URL uploads for analysis, Spaces for collaboration.
- An API (Sonar) for embedding "answers with sources" into your product.
Get started in 5 minutes
- Open perplexity.ai (free, no sign-up needed for basic queries).
- Ask your question in plain words; click the citation links to verify.
- For a hard topic turn on Pro/Deep Research; for code, grab the Sonar API.
When to use it, when not to
- ✅ Use it if you need fast research and fact-checking with verifiable sources.
- ✅ Use it if freshness matters (recent events, prices, releases).
- ❌ Skip it — go with "Google AI Studio" or a chat model — if you want creative generation without source lookup.
- ❌ Skip it — go with "vidIQ" — if the job is narrow: YouTube research and optimization specifically.
The honest price
A free tier with a cap on advanced searches; Pro is a subscription (more Pro searches, stronger models, Deep Research). The Sonar API is billed per token or request. Exact numbers are on the vendor's site and they change.
Gotchas
- Citations aren't always 100% relevant — check key facts against the sources themselves.
- Hallucinations happen, especially beyond the sources — don't trust it blindly.
- The free mode's depth is limited; the best of it is on Pro.
- Answer quality depends a lot on how you phrase the query.

in Perplexity and want a reliable answer with sources. Help me phrase a precise query (plus clarifying sub-questions for Deep Research), set the focus by source type or domain, and build a checklist of facts I must double-check against primary sources. I need the output as <bullet points / a table / a short report>.
