Perplexity
An AI-powered search engine that answers with cited sources
- No Sign-up
- Freemium
- New
Perplexity is an AI-powered search engine, and its premise solves the biggest problem with AI tools: hallucination. Instead of answering from stored knowledge that may be wrong, it searches the web live and gives you an answer with a source link for every claim.
Which means you can verify, rather than believe and hope.
What sets it apart
- Sources for every answer: each statement is numbered and linked to a reference you can open
- Focus feature: choose your source type — academic, Reddit, news, or the general web
- Faster than manual research: for questions requiring several sources
- Image and file search: upload something and search based on it
- Follow-up questions: it suggests questions that deepen the research automatically
How to use it
- Go to
perplexity.ai(usable without an account for a limited number of queries) - Type your question in the search box
- Pick a “Focus” to set the source type before searching
- Check the cited sources — don’t stop at the answer; open the reference for anything important
- Use the suggested follow-ups to go deeper
When it beats the alternatives
- Research and articles: when you need information backed by references
- Product comparisons: it pulls reviews and prices from multiple sources
- Recent events: because it searches live, its information is more current
- Fact-checking: the fastest way to verify something you heard
Who it’s for
A good fit if you’re a student or researcher, a journalist or content writer who needs sources, doing research before a purchase, or simply hate opening fifteen tabs.
Not a good fit if you want creative writing or long-form drafting (not its strength), need an assistant that works on your files, or want coding help.
Limits and warnings
A source existing doesn’t make it a good source. It sometimes cites a random blog or an old article. The responsibility is yours to open it and judge its quality — especially on medical, financial, and legal topics.
It can summarize a source inaccurately, so going back to the original matters for anything sensitive.
It specializes in research, not production. For a full article in a specific voice, ChatGPT or Claude fit better.
Alternatives
ChatGPT with search enabled does something similar but with less disciplined citation. Gemini also searches and ties into Google. But as a dedicated sourced-research tool, Perplexity is the clearest option in the category.

❓ Frequently Asked Questions
How is it different from Google?
Google gives you links to read yourself. Perplexity reads the sources and gives you a direct answer with a citation for each claim. For simple lookups Google is faster, but for questions that require pulling together several sources, Perplexity saves real time.
How is it different from ChatGPT?
ChatGPT answers from stored knowledge and can invent things. Perplexity is built on live web search, and every claim is tied to a source you can open and verify. If accuracy and citation matter most, Perplexity fits better.
Are its sources reliable?
Usually, but not always. It sometimes cites a random blog or an outdated article. The advantage is that the sources are right there, so you can judge for yourself — which is exactly what you should do for any serious research: open the source and check.
Is the free plan enough?
For normal use, yes. Basic search is unlimited; advanced Pro Search has a daily cap. If you do heavy research daily, the subscription is worth it.
What is the Focus feature?
It lets you choose which kinds of sources to search: academic for peer-reviewed papers, Reddit for real user opinions, news for events, or the general web. Picking the right source type makes a large difference to answer quality.
