## What is RedReplier?

RedReplier is a social listening tool that turns Reddit, X, Bluesky, and Hacker News into your cheapest lead channel.

Every day, people post asking for exactly what you sell. RedReplier watches all four platforms for the keywords that matter to you and alerts you the moment a buying conversation starts — so you can show up while the intent is still hot, instead of refreshing search pages for hours.

It comes with real-time keyword monitoring across every subreddit and platform, instant alerts (real-time, hourly, or daily digests), and smart relevance ranking that scores each match on buyer intent, product fit, and freshness — pushing the strongest opportunities to the top and the noise out of the way. Filter by score, platform, keyword, or status, see exactly why each thread matched, and track conversations from new to handled in one clean feed.

The one thing it will never do is post for you. RedReplier finds the conversation and gives you the context; you write the reply and show up as a real human. No AI spam, no auto-posting, no burned accounts.

Pay-as-you-go from the price of a coffee, scaling with the number of keywords you track. Built for founders, indie makers, and…

**Best for:** Indie hackers, small business
