XThe X Algorithm
Free tool

The follow-back check.

See which accounts you follow don’t follow you back. Follow ✓ sorts them in chronological order, oldest first, and separates blue checks from everyone else. Open a list and unfollow accounts one at a time.

In review at the Chrome Web Store How it works

Version 1.2.9 · Chrome, Edge, Brave and anything else built on Chromium · free, and free of charge for good

The panel open on x.com, showing the accounts that do not follow back

Why you would want it

X will not let you follow more than 5,000 accounts until your own follower count catches up. Every account you follow that never follows back is one of those places, spent on somebody who will never see you. Clearing them is how you get room to follow people who will follow back, read what you post, and count toward the 500,000 impressions the rewards program asks for.

What it does, in order

  1. You open x.com signed in, the way you always do.
  2. You press the button. It reads your own following list, the same list the page itself reads, and works out who does not follow you back.
  3. It sorts them in chronological order. X does not publish the date you followed anyone, but it does return the order. Follow ✓ uses that order, oldest first.
  4. Two lists. Blue checks in one, everyone else in the other, so you can treat them differently.
  5. One click is one unfollow. It never unfollows anything by itself, and it stops you at fifty an hour, because X limits accounts that churn follows in bulk.

What it can see, and what it cannot

It can

Run on x.com, and only x.com. Read the following list of whoever is signed in. Unfollow an account when you press the button next to it. Remember, in your own browser, who followed you last time, so it can tell you who dropped you since.

It cannot

Run on any other website. See your password: it never handles one. Post, reply, like, follow anybody, or read your messages. Send anything anywhere: there is no server behind it and no account to make. Work at all if you are signed out.

How to check that any of that is true

You should not take a stranger's word for what an extension does, least of all on X. So:

  • Check the permissions. Chrome tells you what it asks for before you install: x.com only. There is no "read your data on all websites" here, which is the one to be frightened of.
  • Watch the network. Press F12, open the Network tab, run it. Every request goes to x.com. There is nothing pointed at this site or anywhere else.

Questions people ask first

Does it need my X password?

No, and it never will. It works because you are already signed in to x.com in that browser. It can only ever act on the account that is signed in, in that tab, on that computer.

Can it get my account limited?

Unfollowing hundreds of accounts quickly can, whoever does it and however they do it. That is why this one stops at fifty an hour and tells you to come back later. Nothing is automated: each unfollow is a button you press.

Do you see my list?

No. There is no server involved. Your following list is read by your browser and stays in your browser. Your last check is saved there too, so you can close the panel and carry on where you left off instead of reading thousands of accounts again. None of it leaves your machine, and clearing your browser data for x.com removes it.

Is it free?

Yes, free, and not a trial. It exists because the book it comes from is about how X actually works, and this is one of the things the book tells you to do.

What if X changes something and it breaks?

It will say so rather than pretending. Then it gets fixed and Chrome updates you automatically.

This is one page of the book

The tool clears the dead weight. The book is what to do with the room it frees: what the feed rewards, what silences you, and the plan to reach the 500,000 impressions the rewards program asks for. It is updated every month, and updates are free.
