How it works

Three clicks from install to your first 30 replies. No coding, no API keys, no setup.

Built X Grower — a Chrome extension that took my own X account from 0 → 111 followers in 17 days as an indie founder.

Frequently asked

Will my X account get banned?+

Honest answer: any automation carries some risk. The builder runs this exact loop on his own account every day and has not been flagged — but that's n=1, not a guarantee. We add randomized human-like behavior (bezier mouse paths, character-by-character typing, scroll simulation, randomized delays) to reduce detection risk, and if your account does get banned we refund your unused credit. If you're cautious, run it on a non-critical X account first.

When and how do I pay?+

You don't have to. The free tier gives every new account 10 replies/day and up to 100/month — no card, forever. If you want unlimited replies, Pro is a LemonSqueezy subscription, cancel any time, with a dual-price tier: the first 500 paid users lock $9/mo for life (founding cohort), and from the 501st paid user onwards it's $19/mo standard. Separately, the first 100 X users to reply "I'm in" on Felix's pinned tweet get an invite code that unlocks 30 days of Pro free. The 30-day trial is independent of the price lock — when the trial ends and a holder converts to paid, they get $9/mo lifetime if paid-user count is still under 500, otherwise $19/mo.

Do you store my X password?+

No. The extension runs inside your own Chrome browser, where you are already logged in to X. We never see your X cookie, password, or DMs. We only see the post text you reply to and the AI-generated draft.

How does follower growth actually work?+

You search for posts in growth-relevant keywords, the extension generates an encouraging reply via our hosted AI, dispatches it as a reply, and moves to the next post. Your account becomes visible to active users in those threads. Some follow back. Real example: Felix, the builder, went from 0 to 76 followers in 4 days using this exact loop.

Can I customize the reply tone?+

V1 ships with one tone — "Encourager" — because it is the validated highest-conversion template. Future versions will let you add custom templates per niche.

Is this Chrome extension public?+

V1 launches as a sideload (Chrome → Developer mode → Load unpacked). Chrome Web Store version is in review (~2 weeks). Sideload guide is included in your dashboard after signup.

Does this work on Mac / Windows / Linux?+

Anywhere desktop Chrome runs. Mobile Chrome / Safari / Firefox are not supported in V1.

What about refunds?+

If your X account gets banned, submit a screenshot via support and we refund your unused credit balance.
