Windows app · 14 days free · no card

Get more followers and views on X, without spending your day on X.

Hyper X Ultra is a small program for your Windows PC. It reads the posts in your X feed, writes a reply (a comment under someone's post) that sounds like you, and posts it for you at the pace a careful person would keep. It also helps you write your own posts and tells you how well they are likely to do before you publish.

$29 a month after the trial. You sign up with your email. Your X password never leaves your computer.

Shipped my first SaaS at 2am and got 3 signups by lunch. Is it normal to feel this terrified and this alive at the same time?

Completely normal. The terror means you care, the alive part means you shipped. Three signups before lunch on day one is a better start than most products ever get. Which of the three surprised you most?

The goal

Everyone wants the same two things: more followers and more views.

Before building, we asked the people who signed up for early access what they wanted from a growth tool. Two answers towered over the rest. Every feature on this page exists to move one of those two numbers.

Is this for you

Whoever you are, it puts you in front of the people you need, every day.

The people who signed up are not one type. Some sell a product, some write, some want a community, some get views but no followers. The tool does the one job all of them need done daily: it finds posts in your subject, writes a reply (a comment under someone else's post) in your voice, posts it, and follows the accounts that fit you. People who read those posts see your name, click through, and some stay. Here is what that means for each kind of person who asked for it.

If you sell or build something

Your product gets an audience before launch day.

You tell it your subject once. It replies under posts in that subject and follows the people who post about it, so the people who could buy from you see your name every day without you paying for ads.

If you write, draw, film or teach

Your posts stop dying at forty views.

The post writer shows you about ten posts like yours that did well, rewrites yours, and scores it before you publish. The daily replies bring new readers to your profile, where your best work is waiting for them.

If you get views but no followers

Views finally turn into followers.

Views come from one post. Followers come from the same people seeing you again and again. Daily replies in one subject do exactly that, and the follow campaign adds the accounts most likely to follow you back.

If you simply do not have the time

Growth happens while you work.

The app runs in the background on your Windows PC at the pace a careful person would keep. You check the dashboard once a day. Nothing happens faster than a human would do it, which is also what keeps your account safe.

It is not for everyone. It only runs on Windows. It will not post about politics or anything heated under your name, and it will not get you thousands of followers overnight. If you want steady daily growth in a subject you care about, keep reading.

The product

Your account grows every day. You just check the dashboard.

The app sits in your Windows system tray, starts with your PC, and works inside a copy of X that you log into once. The dashboard shows what it did today, how your follower count is moving, and how much time it saved you.

Replies in your voice. It reads each post in your feed, including the pictures and the video, works out what the author is really asking, and writes a reply the way you would. In auto mode it posts the reply. In semi mode it sends the reply to your phone first and you post the ones you like.

Know how well a post will do before you publish it

Draft a post. Type a rough idea. The app shows you similar posts that went viral, gives your draft a score out of 100, and writes two improved versions: one aimed at the most reach, one that keeps your whole message. Each comes with where it would rank among your own past posts.

Grow inside your niche, with people who already like accounts like yours

Follow campaigns. Following someone on X often gets a follow back. The app picks one of your mutuals in a genre you choose, follows their followers at 28 to 40 an hour with a 200-a-day limit, and later unfollows the ones who did not follow back. Your mutuals are never touched.

Keep your account healthy while it works for you

Safety controls. A bot is a program that talks to X's hidden machinery at machine speed, which is what X looks for and punishes. This app does the opposite. It moves a real cursor inside your own X window, stops at hourly and daily limits, sleeps at night, and skips posts you would not want your name under. More on this below.

Proof

Your posts have four times the chance of landing in the top 5%.

We tested the post writer on real accounts it had never seen. A viral-prediction model, a program trained on tens of thousands of real posts and how they performed, scored the original post and the rewrite. Here is what it found. Scoring well is not a guarantee of going viral, and we will never say it is. It does mean the odds are on your side before you press post.

Safety

Your account stays yours. Nothing here looks like a bot, because nothing here works like one.

There are three ways to grow on X. You can do it by hand, you can hand your account to a typical bot, or you can use this. Line them up and the difference is obvious.

Limits counted on our side, so they cannot be bypassed by accident.

Quiet hours every night, so your account sleeps when you do.

Never replies twice to the same post, and never to your own.

No X password stored. You log into X in the app's own window, like a browser tab.

No tool can promise X will never act on an account. We keep the pace conservative and the limits visible for that reason.

Who is already in

More than eighty people signed up before the first build shipped.

They came from the announcement on X and told us what they wanted: an audience for a product, readers for their writing, a community, income from their posts, or simply growth without buying fake followers. Below are some of their public reactions to the announcement, each linked to the original post. They are reactions to the idea, not reviews of the finished app.

Questions

What people ask before they start

What is X, and what is a reply?

X is the social network that used to be called Twitter. People post short messages. A reply is a comment under someone else's post. X shows posts that draw replies to far more people than posts that do not, which is why replies are the fastest way to be discovered.

Will X restrict my account?

It is designed not to. The app never talks to X's hidden machinery. It drives your own logged-in X window with a humanlike cursor, stops at hourly and daily limits, sleeps at night, and refuses to run if it cannot confirm its settings. No tool can promise X will never act, so we keep the limits visible and let you lower them.

Do I sign in with X?

No. You create a Hyper X Ultra account with your email. Then you log into X inside the app's own window, exactly like a browser tab on your PC. We never see or store your X password.

Will the replies sound like me?

You answer a short set of questions about how you write and what you avoid, and the app builds a voice profile from them. Replies respond to what a post is trying to say, in your tone and length, and never invent facts about you or your life.

Does it post without me seeing it?

Only if you choose auto mode. Semi mode sends every reply to your phone first. Both go through the same content screen, and you can switch in one click.

What does it need from my computer?

Windows 10 or 11 and an ordinary internet connection. It sits in the tray, starts with Windows and resumes each day. The installer is about 900 MB because the part that listens to speech in videos runs on your PC rather than on a server.

Mac or Linux?

Windows only today. A Mac version is not scheduled yet.
