What Is ChatGPT? (Overview, Capabilities & Evolution)
ChatGPT is a conversational AI developed by OpenAI and built on advanced GPT language models. It understands prompts written in natural language and responds in a human-like way. Instead of acting like a traditional search engine, it behaves more like a knowledgeable assistant you can talk to.
Over time, ChatGPT has evolved into a powerful tool for content writing, coding, brainstorming, summarization, and learning. Bloggers, marketers, developers, and students often use it to speed up work or overcome creative blocks.

What Is Perplexity AI? (AI Search Engine Explained)
Perplexity AI works differently. Instead of focusing on conversation, it acts as an AI-powered search engine. You ask a question, and it searches the web in real time to generate answers backed by sources.
The standout feature is citation-based AI answers. Every response includes links to sources, which makes it easier to verify information. This design makes Perplexity AI especially useful for academic research, journalism, and fact-based queries where accuracy matters more than creativity.
Core Differences Between ChatGPT and Perplexity AI
The biggest difference comes down to purpose. ChatGPT is an AI chatbot, while Perplexity AI is an AI search engine. One focuses on generating ideas and content, the other focuses on finding and validating information.
Another key gap is transparency. Perplexity AI shows where information comes from, which reduces trust issues. ChatGPT delivers smooth, confident responses, but it doesn’t always show sources. This is why many users rely on ChatGPT vs Perplexity AI comparison guides before choosing a tool for research-heavy work.
