Totally agree, it's amazing, and I'm still using the free version. I work in sales and writing compelling emails can be a pain, ChatGPT gets me away from that 'blank page' state.
I can feed it with excel sheets of data and ask it to summarise, then create the outline of a PowerPoint presentation which I just copy and paste into PP. Gamma AI is also excellent for PPs.
It can give feedback on sales plans, offer suggestions for sales drive ideas, write marketing copy for social posts and newsletters, summarise large bodies of text like white papers, books and contracts, generate images... it's uses really are endless and it has saved me sooooo much time in my day to day.
I also use it for recipes! Just tell it what you have in the fridge and it'll give you recipe ideas and meal plans.
It will always require human intervention but it gives you a foundation that you can work from saving so much time.
Everyone should be learning how to use AI, particularly teachers and they seem to have been the really early adopters of the tech.
There are loads of free courses to learn how to use these tools. As they say, AI won't take your job, but someone who knows how to use AI will!!!
