This is well executed but I feel like I've seen a few of these already, and it never takes that I use them. I always just end up asking ChatGPT what I want to do and then iterating from there. It's usually smart enough to figure me out.
I think the future of this kind of thing is going to be larger companies integrating these kinds of features directly into products, like a super clippy in google docs, spreadsheets, etc. When embedded there it'll cut down on the copy/paste cycle, and I wont need to remember to go use it, it'll just happen.
That's where all the hard work (and gatekeeping) is going to be. Maybe turn this into a browser extension? So people can use the programming prompts for code reviews on github, and the personal planning stuff in emails, and so on.
The site is well executed though, good luck!
