This tool works automatically. It requires no work from me except to answer an occasional email. That's my rule for any side-projects I build.
Anyways, despite a similar tool of mine hitting #2 on Product Hunt last year, this one's PH launch didn't go so well. So it got no traction.
What would you do to market this tool?
I'm not looking for free advice. I'd actually love to partner with someone on this. I'm busy enough with my "main" project, so this hasn't got the attention it deserves.
