ReplyGuyX – AI Auto Reply for X by BlockAI

AI auto-replies to the best posts in your topics, from your own X session. Show up where it matters. By BlockAI.

ReplyGuyX keeps you in the conversations that matter on X — automatically. Tell it the topics you care about and the opinions you hold, and ReplyGuyX writes thoughtful, on-brand replies to fresh, relevant posts from the accounts driving your niche — then posts them through your own logged-in X session, paced like a real person. WHY IT'S DIFFERENT • Posts as you, from your own browser — no third-party server posts on your behalf, and your password and cookies never leave your machine. • Replies in YOUR voice and stance, not generic AI filler. You set the tone and the take; the AI grounds every reply in the specific post. • Conservative, human-like pacing — randomized gaps between replies and a daily cap, so it never looks like a bot. • Early is everything — it surfaces fresh posts so your reply lands while the thread is still live. HOW IT WORKS 1. Subscribe to ReplyX in the BlockAI Mini App and set your topics, voice, and stance. 2. Install this extension and stay logged into your X account. 3. ReplyGuyX pulls AI-written replies for your topics and posts them through your session, spaced minutes apart. You stay in control: pause anytime from the popup, and every reply is visible in your ReplyX history. GOOD TO KNOW • Requires an active ReplyX subscription — the extension only posts for subscribers. • Chrome must be open and you must be logged into X for replies to post. • This is a managed-risk automation tool — keep volume sensible; you're responsible for activity on your account.
