Perplexity combines a powerful LLM with real-time web search to give you cited, up-to-date answers for research, intelligence and fact-checking.

Perplexity is redefining what a search engine can be. Rather than returning a list of links, it reads them for you and synthesises a direct answer — with citations.

**What it does well:**
- Real-time web search with AI synthesis
- Every answer is cited so you can verify sources
- Follow-up questions maintain context naturally
- Pro mode uses GPT-4o and Claude for complex queries
- Spaces feature for collaborative research projects

**Who it's for:**
Researchers, analysts, journalists, students and anyone who needs accurate, sourced answers rather than a list of links to click through.

**What to watch:**
Like all AI tools, Perplexity can misread or misrepresent sources. Always click through to verify important claims, especially for professional or academic work.

**Bottom line:** The free tier alone makes it one of the most useful tools you can add to your daily workflow today.
