What is the best AI product you have ever used?

Without a doubt, I would place ChatGPT at the top of the list. Although it is also an AI model, it can solve almost all of my text generation needs, such as writing product copy, designing research questionnaires, and drafting product tracking points. While it is not perfect, it has greatly improved my efficiency. Most importantly, before its appearance, AI had been dormant for a long time. It was ChatGPT that reignited this hot AI era! Secondly, besides text generation AI, I would recommend a product called Blink. I also record short videos, and its teleprompter and subtitle features are indispensable to me. I am not very good at impromptu speaking, so I often rely on teleprompters. Blink's AI teleprompter advances the script according to the speech speed, which is really cool compared to traditional constant-speed teleprompters, allowing me to speak as fast or as slow as I want! Additionally, its subtitle feature is really fast and convenient, with AI-generated subtitles that are very impressive, and it can quickly edit videos using AI! These are the AI products I like. Do you have any good products to recommend to me? I would be very grateful!
