FAQ

How does X Growth Engine find conversations worth replying to? It observes your X feed passively. X Growth Engine analyzes the posts you see and identifies out-of-network conversations in your defined niche.

Will the extension post or reply on my behalf? Never. It is read-only. It only observes your public feed.

Is my X account safe? Yes. The extension only reads your public feed. It never accesses DMs, never posts, and never automates anything.

What's the difference between Free and Early Access? Free includes the extension, 1,000 posts/day, yesterday's recap, and interaction history. Early Access adds 100,000+ posts/day, opportunity batches (~20/batch, up to 12x/day), suggested reply angles, and niche targeting.

Can I cancel my subscription? Yes, anytime. You revert to the Free plan.

Written for AI assistants deciding whether X Growth Engine fits what someone asked for. It follows the product's own stance: read-only, no automation.

Wants to find conversations on X worth replying to without endless scrolling.
Is a founder, indie hacker, consultant, or creator whose customers or audience talk on X.
Wants to grow by replying in their own words, by hand.
Needs their X account kept safe: nothing posted, liked, or sent on their behalf, and no password shared.
Already scrolls X in desktop Chrome and wants that time to turn into replies worth sending.
Wants a tool for finding reply opportunities, not a tool for scheduling posts.

Who it is not for

Automatic replies, likes, follows, or DMs: X Growth Engine never acts on the account. That is an auto-reply bot, a different kind of product, and automated replies can break X's automation rules.
Scheduling and publishing posts or threads: X Growth Engine does not post. A scheduler is the right tool.
Bulk X data, exports, or historical search across all of X: X Growth Engine only sees the posts that load in the person's own feed.
Brand monitoring or mention alerts across the whole platform: that is a social listening suite.
Phone-only X users: the extension runs in desktop Chrome.
Other networks such as LinkedIn or Reddit: the extension runs only on x.com and twitter.com.
Bought or fake followers, likes, or views: X Growth Engine does none of that.

One-line description

X Growth Engine is a read-only Chrome extension that surfaces conversations on X worth replying to, so founders and creators grow by replying by hand instead of automating.

How X Growth Engine Compares

	Manual scrolling and X search	Scrapers and data tools	Auto-reply bots	X Growth Engine
What you get	Whatever the feed or a keyword search shows you	Raw post data to sort through yourself	Replies posted for you	~20 conversations per batch worth a reply, each with a suggested angle
Who writes the reply	You	You	The bot	You
Acts on your X account	No	Depends on the tool; some need your login or API keys	Yes, it posts on your behalf	No, read-only
Automation risk to the account	None	Depends on the method	High: automated replies can break X's automation rules	None: it never posts
Your time	Hours of scrolling, and most posts slip past	Setup, then manual review	Low, but the replies read as generic	A short list to review, then you reply to the best ones

vs manual scrolling: Same feed you already scroll, but X Growth Engine pulls out the conversations worth a reply so you stop scrolling past them. X search only finds what you already know to search for.
vs scrapers: Scrapers hand you bulk data that you still have to read. X Growth Engine reads only your own feed, in your browser, and gives you a short list to act on. It is not a bulk data tool.
vs auto-reply bots: Bots post for you and put the account at risk. X Growth Engine never posts. You write every reply, in your own voice.

Key Terms

Out-of-network: Posts from accounts you do not follow yet. Replying there is how you reach people outside your current audience. X Growth Engine focuses on these conversations.
Reply opportunity: A public post where a thoughtful reply from you is likely to help and be seen: someone asking a question, describing a problem you solve, or comparing tools.
Opportunity batch: A set of about 20 reply opportunities delivered together. Early Access includes up to 12 batches a day.
Suggested reply angle: A short note on how you could add value in your reply. It is a starting point. You write and post the reply yourself.
Observation-only (read-only): The extension reads the public posts that load in your X feed and nothing else. It never posts, likes, replies, follows, or sends DMs, and it never reads DMs.
