PostMine

Write posts and replies in your own voice right on X. Uses your PostMine account and credits.

PostMine puts your AI writing assistant for X right inside x.com. Write posts and replies that sound like you, without switching tabs. WHAT YOU GET • A composer next to X Open the PostMine side panel on any X page. Write a post, add images or a GIF, save it as a draft, schedule it, or publish it to your X account. Your Drafts, Scheduled and Posted lists are one click away. • Reply help in X's reply box PostMine adds Generate and Improve buttons to X's reply box. Generate suggests a reply to the post you are answering. Improve reworks your own draft: fix the grammar, translate it to English, add a hook or more details, or change the tone to engaging, humorous, creative, sarcastic, inspirational or concise. You can also type your own instruction. • Improve in X's post boxes Improve also works where you write new posts on X: the "What's happening?" box at the top of Home and the Post window. Write your draft, click Improve, and compare the suggested version before you accept it. PostMine only changes the post box you are working in, and nothing is posted until you click X's own Post button. • You stay in control Every change appears as a before-and-after comparison right in the reply box. Accept it or reject it. Nothing is posted until you click Reply or Publish yourself. • Your voice, one account During setup on postmine.tech, PostMine learns how you write, so its suggestions sound like you. The extension uses the same PostMine account and AI credits as the website, so there is nothing new to set up. HOW TO START 1. Create a PostMine account at https://postmine.tech.
