All the self-promotional posts about your AI products and services should go in this mega thread as comments and not on the general feed on the subreddit as posts, it'll help people to navigate the subreddit without spam and also all can find all the interesting stuff you built in a single place.
You can give a brief about your product and how it'll be of use, remember - better the upvotes/engagement, users can find your comment on the top, so share accordingly!
