Perplexity AI is good for fast, reliable information retrieval with live web data, transparent citations, and concise summaries—making it ideal for research, academic work, content creation, fact-checking, business intelligence, technical reference, and more.
However, for users who want an all-in-one solution for searching, image generation, video creation, and coding, Perplexity’s capabilities are relatively limited—and subscribing to multiple AI tools can be very expensive. Don’t worry, though. You can try GlobalGPT, which integrates over 100 top official AI models, including Perplexity, ChatGPT 5.2, Nano Banana Pro, Sora 2 Pro, and Gemini 3 Pro. It offers powerful, diverse features at a very affordable price.
