I use ChatGPT daily for emails (including this one), content creation, video scripts, brainstorming ideas, and even for some random stuff (like debating with a friend). You can also use the voice option, which is pretty impressive for answering any kind of question. It's a bit scary because it sometimes makes me lazy to think or create on my own, but my productivity has probably increased by 200-300%.

Basically, you can "teach" Cody any documents you want, and it will create content based on those sources. However, now that I'm paying for the new ChatGPT version, the answers are actually just as good, if not better. The only real advantage Cody has is that you can organise your conversations, customize the "voice and tone" of emails or any other text you’re trying to create. I'm learning about what is API and how to use it right now because it seems to me that we could greatly benefit from this to delegate small and time-consuming tasks.
from my understanding this is the future of automatization
