What you get
A self-contained HTML report you can sort, filter and share, plus a CSV for spreadsheets and a JSON file. Everything is built in your browser from what X already shows you when you scroll.
- A score per follower and the reasons behind it, so you can disagree with any of them.
- Your audience by size: how many of your followers are tiny, medium and large accounts.
- Filters for score, "never posted", "default avatar" and "joined this month".
- CSV export of the full scored list.
How to run it
Five steps, on a computer. The guided setup on the home page adapts them to your system and username.
Open your followers list on X
On a computer, log in to X and open x.com/yourname/followers. If the page was already open, reload it right before pasting: the tool reads the list as X loads it.
Open the browser console
Press Cmd+Option+I on a Mac or F12 on Windows and Linux, then click the Console tab.
Copy the script
Use the copy button on this page. The script is plain text you can read; it lives at x-utils.com/dist/follower-quality.js.
Paste it in the console and press Enter
The first time, the browser asks you to type "allow pasting" first. Type it, press Enter, paste again.
Wait, then open your report
1 to 3 minutes for a few hundred followers. X limits how fast followers can be read: with thousands, expect pauses of several minutes, handled automatically. The report and a CSV land in your Downloads folder.
Why this is safe
The script runs inside the X tab where you are already logged in. It never asks for, reads or stores your password, cookies or keys.
There is no server behind this. The report and the spreadsheet are written straight into your Downloads folder.
No tool follows, unfollows, blocks, likes, posts or deletes anything. It scrolls and takes notes, like a very fast assistant looking at your screen.
The code is open, short, in plain JavaScript and published on GitHub. If you know a developer, ask them to look.
Questions
Is a high score proof that an account is a bot?
No. It means the account looks like many bots do: no avatar, no posts, brand new, follows a lot. Real people sometimes look like that too, which is why every reason is shown.
Does it remove or block anyone?
No. It reads and scores. What you do with the list is yours to decide; the blocked and muted export exists if you want a backup of what you block.
