What is Perplexity AI?
Perplexity combines a powerful LLM with real-time web search to give you cited, up-to-date answers for research, intelligence and fact-checking.
Full Review
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.
✅ Pros

❌ Cons
- Can occasionally misrepresent source content
