Post Editing & Undo

Browser console script for editing existing posts or undoing a recently posted tweet.

⚠️ X Premium required — Post editing and undo are Premium-only features.

Script Selection

Goal	File	Navigate to
Edit an existing post	`src/editPost.js`	`x.com`
Undo a post within 30 seconds of posting	`src/editPost.js`	`x.com`

Quick Start

Edit a post

Go to x.com
Open DevTools (F12) → Console
Set mode: 'edit', postUrl, and newText in CONFIG
Paste src/editPost.js → Enter

Undo a post (must run within 30 seconds of posting)

Post your tweet
Immediately open DevTools (F12) → Console
Set mode: 'undo' in CONFIG
Paste src/editPost.js → Enter

Configuration

const CONFIG = {
  mode: 'edit',         // 'edit' or 'undo'

  // Edit mode:
  postUrl: 'https://x.com/nichxbt/status/123456789',  // Post to edit
  newText: 'Updated tweet content here',               // New text

  minDelay: 1000,
  maxDelay: 2000,

};

Notes

Edit window: X allows unlimited edits on Premium (unlike Bluesky's 5-minute limit)
Undo window: The undo banner only appears for ~30 seconds after posting
Edit history is publicly visible — a small edit badge appears on edited posts
Script navigates to the post URL automatically when postUrl is set
