This is one of the more interesting projects I have done, and now the 7-day challenge is essentially overwith.
The Executive Assistant for me now does e-mail summaries* of what I missed and I believe it can also do research on whatever topic I want it to give using the whole Perplexity API key sort of setup.
One thing I noticed is that folder organization is quite important for these things, and I can also try to further iterate on the improvement on the Executive Assistant, as I see it to be a helpful tool.
Overall, the whole 7-day course was challenging but fun. It's (hopefully) only up from here and now it's time to MONETIZE such skills.
