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.

Runs on
Chrome, Edge, Arc and other Chromium browsers

What it does

01

Private labels and notes

Label and annotate any account. Your labels show up in the timeline, on profiles and in follower lists.

02

Archive an opinion

Save what someone said in a given post, along with a link back to the original.

03

Interaction counts

See your replies, quotes, reposts and likes for any account.

04

Filter by several labels

Combine labels to narrow down the accounts you have recorded.

05

Import and export

Export all of your local data whenever you want, or wipe it in one step.

06

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. 1

    Download and unzip the file to get a folder.

  2. 2

    Open chrome://extensions/ in Chrome.

  3. 3

    Turn on Developer mode in the top right.

  4. 4

    Click "Load unpacked" and select the folder you just unzipped.

  5. 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.

FAQ

Does it need my X password?

No. It only reads what is already on the page once you are signed in.

Can people see the labels I give them?

No. The data exists only in your own browser, and there is no upload path.

What happens to my data on a new computer?

Export it from the settings page and import it on the new machine.

Is there a Firefox version?

Not at the moment.
