What is GrowX?
GrowX is a Chrome extension that brings the daily work of growing on X into one lightweight dashboard. Instead of juggling a follow tool, a scheduler and a separate analytics app, it combines smart auto follow, post and thread scheduling, account analytics, unfollower tracking and an on-device AI writer in a single place. It's built by an indie founder for creators, founders and small accounts, and it's free to start.
Who it's for
- Creators building an audience — who want to post consistently and understand which content actually brings followers.
- Founders growing in public — who need to find the right people to follow without spending hours on manual outreach.
- Small accounts starting out — who want sensible, paced growth tools and a clear view of who follows back and who doesn't.
Key features
Smart auto follow
GrowX follows the newest followers of accounts in your niche, one at a time with breaks and caps, and keeps going in the background until you press Stop. A follow-back score from 1 to 99 plus filters help skip bots and inactive accounts before you follow anyone.
Post scheduler
Write posts and threads with images, then post now, schedule, or drop them into queue slots on a calendar. GrowX learns your best time to post from your own posts and when your followers are active, and a thread splitter counts characters the way X does.
Analytics
See views, likes, replies, reposts and engagement for every post, along with a heat map of your best times and the topics and formats ranked by engagement. Data refreshes every three hours while x.com is open.
Unfollower tracker
X doesn't tell you who unfollowed you, so GrowX checks your follower list once a day and shows every change day by day. You can also clean up accounts that don't follow back at a safe pace.
What stands out
GrowX does the daily work of growing on X in one place — paced like a careful person, not a bot.
The extension works inside your own x.com session and never asks for your X password, and it backs off automatically when X signals a limit. The on-device AI writer keeps your drafts and data in your browser rather than sending them elsewhere. Small touches like a command palette, daily goals and streaks, and an emergency stop shortcut show it's built for everyday use rather than one-off campaigns.
Worth checking out if…
You're serious about growing on X but don't want to stitch together several separate tools to do it. If you want paced auto follow with guardrails, scheduling tied to your own best posting times, and a clear picture of who follows and unfollows you, GrowX bundles all of that into one free-to-start Chrome extension. It's a natural fit for creators and small accounts who'd rather spend their time writing than managing a stack of apps.
