ReplySurge is a Chrome extension that reads any post on X, Reddit, and LinkedIn and writes you on-brand replies in seconds, learning your voice from every reply you post. You paste them yourself, so you grow 10× faster without ever getting flagged as a bot.

Hey Product Hunt 👋 I built ReplySurge after watching every "AI comment" tool either get its users flagged or get itself removed. X blocked programmatic replies. The only workflow that survives is human-paste: the AI drafts, a human decides and posts. So ReplySurge sits next to your feed as a chrome extension. Open any post on X, Reddit, or LinkedIn, and it automatically reads what was actually said, drafts a reply in your brand voice. Promotion is dialed per platform (subtle on Reddit by default). You paste and hit reply yourself, so your account keeps a fully human footprint. It learns from the replies you actually post, so it sounds more like you every day. No tool covered all three platforms together, and none of them was built "safe first." That's the gap. Free to install, free 7 day trial, no credit card. I'd genuinely love feedback on the reply quality, that's the whole product. Ask me anything.

Love the voice-matching angle, that's the bit most reply tools get wrong. One thing that would make it sticky for me: a quick "tone slider" so I can nudge replies from playful to professional without retraining anything. Would save a ton of manual edits when I'm jumping between a casual Reddit thread and a more formal LinkedIn post in the same morning.
