Replydaddy is a marketing assistant built around Reddit, helping founders and growth teams turn the platform into a steady source of traffic and leads. It scans subreddits for posts that match your product or keywords, then surfaces conversations where joining in could be valuable. Once a relevant thread is identified, Replydaddy uses AI to draft contextual replies that mention your product naturally rather than as overt promotion. Users can review, edit, and post responses, with the goal of building authentic engagement and inbound interest over time. The tool is aimed at indie hackers, SaaS startups, and marketers who want to tap Reddit's communities without spending hours manually monitoring feeds.

  • Keyword and subreddit monitoring
  • AI-generated contextual reply drafts
  • Lead and thread discovery dashboard
  • Editable responses before posting
  • Brand and product context training
