Do you use TikTok to promote your SaaS? How?

I am running a growing SaaS product (AI-based writing assistant and learning engine called linguix.com), and I am working on marketing.

I read very often that TikTok is booming and is a perfect place for a startup promotion. However, when I read articles on the topic they all write about offline businesses, fashion brands, etc. No SaaS.

So, the question is, do you know any successful SaaS campaigns on TikTok? Or, even better, maybe you did such campaigns by yourself? If yes, I'd be happy to learn more on your experience and buy you a coffee!
