First Impressions
It's the tool that started it all. I use it daily for brainstorming, drafting emails, summarizing articles, and even debugging code. It's a generalist, but incredibly powerful when prompted correctly.
Best Feature: Custom Instructions
Setting up custom instructions means I don't have to repeat myself. I tell it my role, my preferred tone, and my goals, and it remembers them across conversations, making every interaction more efficient.
The Verdict
The foundational AI tool. If you only use one AI, this is it. It's a Swiss Army knife for productivity and creativity.
