Turn Build in Public replies into daily growth.
XJumper's desktop Agent reads the Build in Public community, picks relevant posts from builders, and replies in your voice from your own browser. Up to 50 thoughtful replies a day, paced like a human.
The best builder conversations happen while you are shipping
SaaS and indie developers win on X by showing up in useful conversations, not by blasting generic posts. XJumper watches the Build in Public community, chooses posts where you can add something specific, and replies from your own desktop browser so you stay present without living on the timeline.
How the agent works
Three steps, then the daily reply loop runs itself.
Connect your desktop Agent
Install the Agent and connect your X session. Replies come from the same browser and account you already use.
It finds builder posts
XJumper reads the Build in Public community, filters low-fit posts, avoids duplicate authors, and drafts replies in your voice.
agent.how.step3.title
The Agent publishes up to 50 thoughtful replies a day, never the same post twice, with optional follow-up actions kept under safety limits.
One subscription. The agent plus three tools.
At $29.99/month, the Growth Agent comes with Search Post, Target Monitoring, and Smart DM included.
Built to look exactly like you
X gets suspicious when automation looks robotic. The Agent is designed to look like your normal desktop session.
Your own machine
The agent runs locally in a real browser on your computer, not from a data center X has never seen.
Your real fingerprint
Every action uses your real session and device fingerprint, so it looks exactly like something you did.
Human pace
No risky bursts. The agent acts at a natural, throttled cadence that respects X's limits.
