Yes I believe it's possible, but it depends on whether your audience perceives if they will get value at a level which is worth more than whatever your sale price is. Also, and I hope this is obvious, you need an actual audience of people interested enough in AI to financially invest in learning more about it. My advice is 1) know exactly who you are going to sell this to, and 2) Create the first newsletter, publish it publicly and then promote it to see who from your audience signs up. If you don't already have an audience you're going to need to build one.
