Short description Private labels and notes for X accounts, plus a record of your interactions. All data stays on your device. Detailed description ■ What this is Who's Who is an extension for X (formerly Twitter). It lets you attach your own labels and notes to any account you come across on your timeline. X constantly surfaces people you don't follow, or someone you exchanged a few replies with months ago. "I've seen this person before." "They said something about this — but what was it?" This extension removes the need to open their profile and scroll back through their posts every time. ■ What changes once you install it · You immediately know who a familiar account is 　Label an account once, and the label appears next to their name the next time they show up on your timeline. The same labels show on their profile page and in follower / following lists, so remembering takes no action at all. · You keep what they said, with the evidence 　Save the post itself, not just your impression of it. Add a topic, a stance and a note; the link back to the original post is kept, so you can always check the wording later. · You can see your actual distance from someone, as numbers 　Likes, replies, reposts / quotes and mentions are counted in both directions — "them to you" and "you to them" — so you can tell at a glance whether it is a real back-and-forth or you reacting one way. Past interactions can also be collected afterwards (only publicly visible replies, mentions and quotes; reposts cannot be recovered because X does not publish that history). · You can find people again later 　Combine labels, for example "Infra" AND "Watchlist", to filter the accounts you have recorded. · Japanese / English / Chinese 　The interface follows X's own theme (Light / Dim / Dark), so it does not look out of place. ■ About your data · Labels, notes, saved posts and interaction counts are stored only inside your own browser (IndexedDB). · This extension does not send data to any server. It contains no code for doing so. · Simply viewing a page stores nothing. Data is written only when you record a label or a note yourself, or when one of your own actions (a like, a reply) is observed. · It never follows, likes or posts on your behalf. · You can export all of your data at any time, or delete all of it at once. This extension is not affiliated with X Corp. in any way.
