I use ChatGPT 4 many times a day for creating first drafts of content.
You need to think about how you frame questions...it isn't Google and using it like that won't get you brilliant results.
Examples of what I might say are
"Imagine that you're a <my role> working in a <certain type of company> and that you need to draft a <whatever you need>.
Make sure you include <anything that's a must have>.
Use a <professional but approachable> tone of voice and UK plain English."
You can get it to edit it's own work too...so you can check the first draft and say something like
"Can you rewrite this - take out the bits about XYZ and add some content about ABC. Also make it a little shorter"
It can critique its own work too...so you might say "Imagine you're an expert in <this area> and you review the draft just wrote to critique it. What are your conclusions?"
It will tell you its conclusions and automatically does another draft taking them into account.
You can also ask it "Is there anything else you need to know from me to make this draft even better?"
It will tell you what questions it would like to ask and then when you answer them it will redraft again.
I save prompts like this in OneNote so I can copy, paste and tweak rather than write out from scratch.
I still have to make little tweaks as it tends to have a tone of voice that is 'a bit much' for English sensibilities but it cuts my writing time in half, if not more because all of the work above (including all the research I might have done before a first draft) is reduced to a few minutes of my time.
I don't tend to sit and wait for it to answer...I'll usually be asking it questions for a future piece of work in between working on something
I would recommend trying GPT4 for one month and focusing on getting good at working out how to ask questions in a way that gives you something close to what you need. It's $20 but you can always cancel before the month is up (I highly doubt you will though! This is the only thing I've ever paid for myself).
GPT4 is significantly better than GPT3.5 (which is the free one).
As for corporate policies - register in your personal email account. Never include any company information or keep it so generic that it doesn't count as company information and never share any company documents with it.
That means you won't breach any policies.
