The initial version of this actually used Mighty, but I didn't find any free tier available, so I switched to Cohere to keep the $0 pricetag.

Mighty is free if you're not making money from it. You could have used Mighty and I would have been glad to help you set it up :)

There's a bit of a difference between what you see following the 'purchase' link and what you see if you scroll down to 'pricing' on your site. It confused me at first too - I'm just so used to seeing a 'pricing' link in the top bar, I pretty much always go there first to see if there's a reasonable free tier for me to play with something.
