Braina has pricing, after a few clicks.

Mycroft is all FOSS

Kitt seems all FOSS too

It's clear you're trying to discover the right price and of course it's complex. Please be upfront about it, what you've said here could be copy-pasta to your site already.

I want to like your project too but currently the others are doing a bit better on presentation.
