People who make useful content and services intended for interactive human use available for free have written at length about the ongoing issues with AI crawlers scouring the web in an insatiable search for new training data.

Some people are coming up with interesting technical solutions to the problems posed by AI crawlers, but I have ultimately opted for a much simpler solution: a paywall.

Kullish is a project that I operated free of charge for all users from 2020 until January 2025.

User comments and discussions on the internet have a pretty bad rep these days, to the point where many people have just opted out of online commentary completely, going as far as using a combination of DNS filtering and browser extensions to remove them entirely from their browsing experience.

I, on the other hand, have spent the last couple of years refining ways to separate signal from noise in the cacophony of online user commentary, as I have come to believe that the most valuable knowledge I acquire on a daily basis comes from commentary and discussion rather than publishing.
