I'd be scared shitless to even try something like this. There is just a pretty website, a video, and a blog post. No info on the founders, I can't find anything on LinkedIn, just a company Vineyard Finance LTD that was incorporated last year.

We're all unhinged about the data we're giving LLMs but here I'd draw the line. I'd rather keep paying the small amount I pay to have my accounts done.
