ChatGPT is like a super-smart chat application that can answer loads of questions. There are two versions. The first, ChatGPT-3.5, is free but sometimes gets things wrong. The second, ChatGPT-4, costs $20 every month, but it’s way smarter. It can help come up with business ideas, plan out marketing stuff, look over papers, and even help write emails. Using it feels like talking to the smartest person ever. However, it’s not updated with events or trends post-2022.
