RedReplier, an AI-powered Reddit monitoring and social listening tool based in Gdansk, Poland, launched on June 23, 2026, for founders, marketers, and agencies. It watches Reddit, X (Twitter), Bluesky, and Hacker News for buyer-intent keywords, ranks matches by buyer intent, and drafts replies for human review. The tool surfaces the exact threads that ChatGPT, Claude, and Gemini cite, enabling generative engine optimization (GEO) by allowing brands to join conversations shaping AI recommendations. Key features include real-time keyword monitoring across every subreddit with instant alerts, all-platform coverage in one feed, AI relevance grading by buyer intent, product fit, and freshness, and AI-drafted, human-reviewed replies with no auto-posting.
