That's brilliant! How do you advertise/let others discover your product?
I started off by buying Google Ads, but I lost money running them. Eventually I stopped running the ads and focused on writing blog posts. Also I think the domain sort of helps. I wrote a bit more about the start here: https://bankstatementconverter.com/blog/posts/2022-02-25-zer...
Even within a single site, there were often errors at the fringes, especially if things like layout/styling changed, and my concern about giving bad data to users (or needing to constantly be checking data quality and adjusting custom parameters for each target site) held me back from ever feeling confident enough to convert it into a paid product.
I don't mean for you to give up your secret sauce here, but wondering if you ran into this same issue, and what your approach was from a business/customer expectations perspective?
