I like a lot of these ideas. Some of this is built in to the ChatGPT desktop app. Other parts of it could be glued together from existing tools. Others are still beyond the capability of LLMs. Lots of people thinking along the same lines and there will be a lot of products taking a shot at this or similar uses. When one sticks it's going to be a big, if somewhat niche, hit. I know I'd use it.
