  description

  Posting on Reddit consistently drives traffic, builds authority, and puts you in front of the right people. The problem is doing it every day across multiple subreddits without burning out or sounding like a bot.
  
  ReplyDeck handles it. You design a persona with a specific tone, vocabulary, backstory, and target subreddits. It finds relevant posts and writes replies that read like you wrote them. Timing is randomized so your activity looks natural.
  
  It runs on your own AI API key (OpenAI or Anthropic). Your key stays in your browser. We never see your prompts, your replies, or your Reddit data.
  
  Content safety is built in. Filters block AI-sounding language and harmful content automatically. Five rules let you control exactly what gets posted.
  
  Setup takes two minutes:
  
  1. Create a persona or pick from a template
  2. Add your API key
  3. Choose subreddits and hit Start
  
  Your first reply posts in under three minutes. Every reply is logged with a direct link so you can review what went out. Test any persona in preview mode before going live.
  
  Free tier: one persona, no time limit, no credit card. Pro ($29 one-time, no subscription) unlocks unlimited personas, OpenRouter access (100+ models), higher daily limits, and cross-browser sync.

  You know Reddit works. Threads show up in Google, get cited by ChatGPT and Perplexity, and reach people actively searching for what you know. The problem is staying active across 10 subreddits every day without burning out or sounding like a bot.
  
  ReplyDeck handles it. You build a persona — tone, vocabulary, backstory, interests, example replies — and point it at your subreddits. It finds relevant posts, drafts a reply in that voice, and posts it on a randomized schedule so your activity looks natural. Different subreddits get different voices. You define who is replying, not just what to say.
  
  It runs on your own AI API key (OpenAI or Anthropic). Your key stays in your browser. We never see your prompts, your replies, or your Reddit data.
  
  Safety is specific, not vague. Filters strip 15 AI-sounding phrases ("certainly," "as an AI," "game-changing"), block profanity and harmful content, and skip political and religious topics. Five rules, all configurable, all on by default. The reply monitor watches your profile and auto-deletes any reply that gets downvoted past your chosen threshold — damage control that runs while you sleep. A built-in risk indicator warns when your pacing looks aggressive.
  
  Setup takes two minutes:
  
  1. Create a persona (or describe one in plain text and let AI generate it)
  2. Add your API key
  3. Choose subreddits and hit Start
  
  Your first reply posts in under three minutes. Every reply is logged with a direct link so you can review what went out. Test any persona in preview mode before going live — see exactly what it would post on a real thread, without posting.
  
  Free tier: one persona, no time limit, no credit card. Pro ($29 one-time, no subscription) unlocks unlimited personas, OpenRouter access (100+ models), higher daily limits, and cross-browser sync.
