I believe this feature would make FridayGPT truly stand out.
I've seen a few other apps where the app knows the context of the app you're in, and then you are able to prompt the AI without having to explain context yourself, or without having to highlight the entire page each time.
This allows you to greatly enhance your workflow seamlessly. Such as complete the sentence on the line that you're on -> FridayGPT would be able to understand the whole context of the email you're written so far and complete the sentence accordingly.
This would truly allow Friday GPT to be used without interrupting your workflow, as you don't need to highlight text or explain context yourself each time you prompt FridayGPT.
I think my explanation isn't the best, but I'm happy to link to some apps that I've seen that have these features so you can get a better idea.
