What's some good AI software for entrepreneurs?

I just started running a smaller business as a side gig and am in need of getting some manual work off my shoulders. This business is basically a hobby turned business as something I've been wanting to get into for a long time but just got the courage to do so this year. I'm making hand-made jewelry that's kind of a niche but has a tiny little tight market with relatively active and supportive buyers. Of course, a huge part of my job is answering all kinds of questions, covering spreadsheets, and doing market research to try and find new customer groups. The majority of this work is relatively simple what I’d call “manual”, which is why I feel like it could be done by AI, at the very least with the precision that I need.

I did find some help using Chat GPT 4 so far, especially with handling my spreadsheets and market research. I usually let it do some manual labor on the spreadsheets, and I’ve even managed to train it to do some more complex tasks like researching the market and putting the results in the spreadsheet that I can use. ChatGPT isn’t that good at answering messages however because the answers are pretty generic and I have to manually generate responses and send them which takes arguably even more time than just responding myself. For this task, Personal AI has been proven to be way more useful because it’s literally a personalized AI model that can be trained to accurately respond to anything + once you create your own personal AI, other people can ask questions there instead of messaging me directly and get instant responses from the AI that are based on the knowledge I fed it. Still testing the tool, but so far it has been quite useful and saved me a ton of time. I also used Poll the People a few times to get feedback from my customers, and it worked magnificently.

I'd like to hear some recommendations on AI tools that can be useful to someone who's just entering this world so please shoot them!
