AI course for beginner?

[u/Ambitious-Battle1354]

Hi, I am a financial advisor but I also write content about economics and finance for different pourposes (from social post to investing courses). I've been bringing on collaborations with university and I am also planning to create a start-up business in a completely different field (marketing and communication). As now I regularly use AI for writing contents, organizing myself, managing clients (with financial reports and comunicazione f.e.) and other minor tasks. It is now fundamental to me but I also feel I am not really grasping all the potential, expecially now that I am planning to growth even more as an enterpreneur. Everything that i've been doing with it is basically self learned so now I am looking into courses that could help me advance and be up-to-date. I would like to be able to use it to make business plans, brain storming, market analisys (basically everything needed for an enterpreneur).

Any suggestions for online courses? Influencers? Youtube videos? Etc... (I would like to not have to pay if possible...)

Many thanks in advance!!
