How it works

Three steps. About ten seconds.

No dashboards to learn, no campaigns to set up. Open a post, get a reply worth posting, move on.

1

Open any post

ReplySurge reads the post and the thread around it — the real context, not just the headline — right inside your browser.

2

Pick your angle

Choose a tone, dial how much to promote, and it writes a reply in your brand’s voice. One tap to make it shorter, punchier, or less salesy.

3

Copy & post

Paste it in and hit reply — by hand, as yourself. You stay a real person in the conversation, which is exactly why you never get flagged.

Why it’s safe

A bot gets you banned. You don’t.

Auto-posters spray comments at scale and platforms shut them down — bans, shadow-bans, lost accounts. ReplySurge never touches “post.” It only writes; you do the posting, like the human you are.

  • No auto-posting, ever — copy and paste stays in your hands.
  • No suspicious automation footprint on your account.
  • Replies you’d actually write — just far, far faster.

FAQ

Questions, answered.

What is ReplySurge?
ReplySurge is a Chrome extension that reads a post on X, Reddit, or LinkedIn and instantly writes you an on-brand reply to copy and paste. It helps you grow your brand’s visibility by replying faster and more consistently — without running an automated bot.
Will ReplySurge get my account banned?
No. ReplySurge never auto-posts. It only drafts the reply — you paste and post it yourself, so there’s no automation footprint for platforms to detect or flag. That’s the core difference between ReplySurge and the reply bots that get accounts suspended.
Which platforms does it support?
X (Twitter) and Reddit today, with LinkedIn rolling out. The same fast flow works across all of them, so the audience-building habit you build carries everywhere your customers actually hang out.
How is it different from an auto-poster or reply bot?
Auto-posters publish comments for you at scale, which platforms detect and ban. ReplySurge keeps a human — you — in the loop: it writes the draft, and you decide what to post. You move roughly 10× faster than writing replies by hand while still looking exactly like the real person you are.
Will the replies actually sound like my brand?
Yes. You add your company once, or import it straight from your website, and every reply leads with your positioning, talking points, and chosen tone. You can also tune how promotional each reply should be and refine it in one tap.
How much does ReplySurge cost?
ReplySurge is free to install and includes a free trial. Paid plans unlock unlimited reply generation. No credit card is required to get started.
