How to use ChatGPT in my SaaS?

Hi guys!
I've been building my Reddit Marketing SaaS (www.promotee.co) for the last few months and added a lot of features to it to make the marketing process easier for people on Reddit.
As ChatGPT launched last year, it drove everybody crazy and made a whole new place for AI-based startups. Following the trend, I and my co-founder is thinking of adding it to our software as well and using it to solve the major marketing issues of our customers.
We're on to the brainstorming part and will soon be coming up with something really cool.
How ChatGPT is working out for you all btw?
