How to Grow a Very Niche Audio-related Product?

Hi, this is my 1st SaaS and I have a struggle finding users, even those on the free plan.

Not sure if I missed the whole point with it or not.

I usually launched and built WordPress plugins. With the free plugin repository, I usually got 100s of users within months without any marketing.

I am really bad at marketing I guess and don't know what or where to focus.

So I would like to get more feedback on it and what some of you would try to get users to try it.

I know there is market for it, because the competitor rumble.studio seems to do pretty well. Their "ideas" board is active.

I built this tool to help myself record podcast episodes, spending only a few minutes per day when completely busy.

I am currently refactoring the tool a bit to allow interview-like audio with pre-recorded questions. And then focus on SEO and such.

What are your thoughts on using Ads or sponsor newsletters and such? Has something like that helped you acquiring users?

Should I try and pivot it a bit different? Create examples on using it as a tool to record podcasts, audiobooks, testimonials and such?
