Useful tool. Maybe consider adding the inclusion of profit numbers themselves: you have x profit and if you choose the direct route you are left with y, but if you choose the optimized route you end up with z (with z>y).

Interesting tool, I think one of the great things with AI is it can also be an equalizer -- because this kind of tool makes tax optimizations available to SME's too, not just big multinationals!

As a tax advisor specializing in tax planning, I wanted to commend you on a great build (and I am certainly looking forward to TreatyHopper+). As it stands now, this tool will serve as an excellent starting point for tax planning. I emphasize starting point because, as you mentioned in another comment, the practical reality of setting up these structures is often far more challenging than a tool can make it seem. Nevertheless, I believe that if you continue to develop this product, there is a huge market waiting for it. The direction you are taking with TH+ suggests you are on the right track.

I felt the same - I really want an 'ironic' version of this tool which is the same, but exists more to expose this kind of practice than to enable it.

I mean: I didn't do anything illegal. It just using the rules that exist to your advantage (something that any rational agent would do, in order to maximize their utility). Also, there are rules like GAAP and PPT to avoid this kind of behavior, so it is not as simple as this tool (which is an abstraction of reality) shows. It certainly is controversial however, but if you had read the disclaimer at the bottom of the website, you would have already known. Nevertheless, it's now accessible to anyone (whom is rational) and has the means to utilize these types of structures ;)
