I have added a human.json file to my website. https://codeberg.org/robida/human.json is the spec and it contains links to browser extensions that help show a site's status. The file itself can be found at https://starforge.co.uk/human.json

I've added vouches for a bunch of sites I know to be made by humans - if you would like to be added, and you don't use generative AI on your site, send me a message and I can add you.
