About X Growth Engine
What is X Growth Engine?
X Growth Engine is a Chrome extension that observes an X feed and uses Grok to surface niche conversations worth a reply.
What X Growth Engine does
Add the extension to Chrome. It observes posts that cross the feed while you scroll, like, reply, or post. It never posts, replies, sends DMs, or automates anything, and it does not store credentials. Grok then surfaces out-of-network conversations in the niche, with suggested reply angles. Free includes yesterday's recap and interaction history. Early Access adds Grok opportunity batches and niche targeting.
Who X Growth Engine is for
People who scroll X and want niche conversations, reply angles, and a recap of the posts they already saw.
How X Growth Engine works
Install the extension in Chrome. Scroll like you always do. The extension watches the public feed only. Each day, Grok surfaces conversations worth a reply. Feed analytics show posts seen, creators encountered, and reply patterns. Interaction history keeps likes, replies, and retweets. Yesterday's recap lists top creators and the most liked and most discussed posts you saw. Cancel from the Stripe portal and keep access until the billing period ends.
