Open-source extension that collapses unwanted content by keyword on Xiaohongshu, Weibo, X and Zhihu

Browser extensionfreeglobal

Ad Radar is an open-source browser extension that collapses content matching keywords or specific bloggers on Xiaohongshu, Weibo, X and Zhihu, with local keyword filtering and optional AI-based detection of ads, military or political topics using the user's own API key. It's built for people who want finer control over their feed on these platforms than the platforms' own filtering offers.
