ReplyDeck — Scheduled Reddit Replies

Grow your Reddit presence on autopilot. ReplyDeck posts AI replies in your voice using your own API key. Free tier, no time limit.

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, Anthropic, or OpenRouter). 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, higher daily limits, and cross-browser sync.
