The problem
Your posts die quiet. Your replies travel.
Under 5,000 followers, a post reaches almost no one. A reply on a rising thread can reach thousands.

Built in public
One builder. No badge wall.
No “trusted by 4,000 creators” strip, because there aren’t 4,000 customers. One person is building this in the open, with the same under-5k problem it solves.
The radar at the top is the live instance. Revenue and follower counts get posted as they happen, including the zeroes.
FAQ
The questions worth asking
Short answers. Anything else, ask on X.
Is this against X’s rules?
No. It runs on X’s official API with your own OAuth connection, and every reply needs your explicit confirm. There’s no automation X could object to.
Will the replies actually sound like me?
The voice profile is distilled from your own posts, you can edit every word before publishing, and you can rebuild it in one click if your style shifts.
Does it ever post without me?
Never. Explicit confirmation every single time: no scheduling, no autopilot. A failed publish is never auto-retried, so you can’t double-post either.
What exactly do the receipts measure?
Follower snapshots three times a day; a receipt states the change in the window after your reply, with the window times shown. Shared windows are split and labeled, unusual spikes flagged. Honest measurement, not a causation claim.
Which niches can the radar watch?
Six today: AI builders, indie hackers, SaaS growth, X growth, AI tools, build-in-public. New ones ship on request, usually within days.
Can I cancel?
The 3-day trial needs no card, so there’s nothing to cancel during it: just stop using it. If you add a card to keep going, cancel anytime in one click via the Stripe portal.
