Who's Who
Private labels, opinion records and interaction history for X accounts.
Who’s Who helps you remember who each X account is, what they have said, and how they relate to you. Every label, note, saved opinion and interaction count lives only in your own browser — the extension contains no upload path and sends nothing to any server.

What it does
Private labels and notes
Label and annotate any account. Your labels show up in the timeline, on profiles and in follower lists.
Archive an opinion
Save what someone said in a given post, along with a link back to the original.
Interaction counts
See your replies, quotes, reposts and likes for any account.
Filter by several labels
Combine labels to narrow down the accounts you have recorded.
Import and export
Export all of your local data whenever you want, or wipe it in one step.
No network access
The only permissions requested are storage and access to x.com. There is no network code in the extension.
How to install
- 1
Download and unzip the file to get a folder.
- 2
Open
chrome://extensions/in Chrome. - 3
Turn on Developer mode in the top right.
- 4
Click "Load unpacked" and select the folder you just unzipped.
- 5
Open x.com — you can start labelling from the button next to any avatar.
It is not on the Chrome Web Store yet, so it has to be loaded manually in Developer mode. Keep the unzipped folder where it is — deleting it removes the extension.
