Staying on top of hundreds of RSS feeds is impossible when every reader just dumps articles in chronological order. RSSMonster takes a different approach: it evaluates, scores, and prioritizes every article so the signal rises above the noise. The three-pane reading interface automatically marks articles as read when you scroll past them, while the built-in quality scoring engine rates content by freshness, originality, trust, and attention metrics. Compose advanced search expressions using field operators like star:true, quality:>0.6, hot:true, and date filters like @today or @lastweek, then save those expressions as persistent Smart Folders for one-click access to curated views. Semantic event clustering groups related articles across sources so you see one coherent story instead of fifteen duplicates. Connect your favorite mobile client through the Fever API (supporting Reeder for iOS) or the Google Reader API (compatible with News+, FeedMe, Vienna RSS, and ReadKit). The AI chat assistant powered by the Model Context Protocol lets you ask questions about your feed content and get summarized answers. Import your existing subscriptions via OPML, switch between light and dark themes, and install the app as a Progressive Web App for offline reading. On RepoCloud, deploy RSSMonster on a dedicated VPS with root SSH access, full data ownership, and persistent storage under the MIT license.
