hcker.news is a third-party Hacker News reader whose filters live in the URL, and ?ai=exclude is the one that drew 199 points on Hacker News itself: the day’s most-upvoted stories, grouped by date, with every AI-related story removed. The same toggle runs the other way, the Atom and JSON feeds follow whatever filters you have set, and a Small Web filter highlights personal sites from Kagi’s domain list. It isn’t airtight — commenters spotted an AI startup’s post at the top within hours — and the feed refreshes every minute.
