Modder takes Valve's AI measures one step further with a browser extension that adds an unavoidable gen AI warning to Steam games to cut out the slop

A modder created a browser extension for Firefox and Chrome that surfaces Steam's AI-generated content disclosure as an unavoidable pop-up before the game page loads, rather than buried at the bottom. Valve requires developers to disclose AI use, but the extension makes compliance more visible to players. Note: the extension only detects existing disclosures—games without proper AI statements will still slip through.
