What it does

Whodis is a contextual note-taking tool for Twitter, inspired by the notes feature formerly available on LinkedIn.

Whodis adds private notes, collections, and bookmark organization directly inside X/Twitter.

Whodis adds a private context layer to X/Twitter — attach notes to profiles, build living collections, and organize bookmarks without leaving the feed where the conversation is already happening. No extra dashboard · Private notes stay personal · Works on x.com Just hover on a name on your timeline, or open their profile page, and your private context is already there when you need it. Share collections with your friends, or make them public for the world to see when your curation is worth publishing. Organize, track, and share collections without leaving X - Whodis lives inside the bookmark flow you alreadyfrom whodis.xyz
