Students, teachers, office workers, and even people at home use AI every day. Two of the most popular tools right now are Perplexity AI and ChatGPT.
You may have heard of both. Maybe you are wondering what each one does. Or maybe you want to know which one is better for schoolwork, writing, or just having fun. It just comes down to what you’re looking for.
Both tools are smart. Both can answer your questions. But they are built for different jobs. In this blog, we will explain how each one works, what makes them special, and which one might be the best choice for you.
What Are They Used For?
Let us begin with a simple explanation of each tool.
Perplexity AI
Perplexity AI works more like a search engine. When you ask it a question, it goes online, checks websites, news articles, and blogs, and gives you the answer with links.
It is great when you want:
- News updates
- Facts with real sources
- Help with research
ChatGPT
ChatGPT is like your personal chat buddy. You can chat with it just like you’re talking to a friend. You can ask it to write poems, help with homework, solve problems, or even just chat for fun.
