What is Perplexity AI?

Perplexity AI is not just another search engine. Launched in August 2022 and headquartered in the tech hub of San Francisco, this AI-powered search engine is the brainchild of Aravind Srinivas, Denis Yarats, Johnny Ho, and Andy Konwinski. Think of it as the love child of Wikipedia and ChatGPT—only smarter, faster, and more conversational.

Features? Oh, It's Packed!

1. Conversational Search: Unlike traditional search engines that give you a list of links, Perplexity AI provides you with direct answers, explained in natural language. It even cites its sources, so you know where the information is coming from.

2. Multiple LLMs: The free version uses OpenAI's GPT-3.5, but the Pro version? It’s like a buffet of AI models—GPT-4, Claude 3, Mistral Large, Llama 3, and more. You can switch between these models to get the best results.

3. Focus Mode: Want to dig deeper? Use the Focus mode to fine-tune your search and streamline sources. It's like having a personal research assistant.

4. Follow-up Questions: Perplexity remembers the context of your queries. Ask a follow-up question, and it will interpret it in the same context, saving you the hassle of rephrasing.

5. Document Uploads: Yes, you can upload your own PDFs, CSVs, images, and more for analysis. Imagine uploading a complex dataset and getting an instant summary. Mind-blowing, right?

6. Multimodal Capabilities: The Pro version can generate text, images, and even simple code. Talk about versatility!
