I wish you the best, but you do not have a product to monetise yet.
IMO: if your goal is to attract users or to make money, you have too many strong free competitors to be using ads like this, especially if your audience read Hacker News. It's not the right business model. Any amount of time spent making these ads 'smoother' is better spent on the product, because you won't earn enough ad revenue to make it worth it.
If you need revenue to pay for hosting, you'd be better off making it open source or self-hostable.
If your goal is getting feedback, you have to recognise that people are doing it for you, not for them. Don't make them pay you to do it.
I'm not sure I agree with 'minimal ads'. On a 27" monitor, 3 banners and an ads privacy pop-up don't take up much screen real estate, but visually some pages have as much ad as content. It's not a great experience when you're competing with other free (or OSS) products. If you're really only looking for feedback, you might have better luck if you aren't trying to monetising the people giving up their time!
Congrats on building this for yourself, I can certainly see the benefit of building writing tools to suit your own needs.
