About Xpert for X: AI replies & growth
Xpert drafts your X replies, posts and threads in your own voice, right where you use X. It never posts on its own: replies and quotes go out from X's own composer when you press Reply there, and a post you write in the side panel is published or scheduled only when you press Publish or Schedule.
ON X.COM
• An Xpert button on every post. Add your take, pick a style (agree and build, ask a question, share your experience, push back, or have some fun) and get a reply that sounds like you, learned from your own posts.
• Compose, remix and rewrite posts and threads in a floating panel, with Hook Lab openings and a viral check.
• Pre-flight reads every draft as you write: how much it sounds like you, AI tells, reach and mute risks, payout safety, and posts it's too close to.
• Predict how a reply or a post will land before you send it.
• AI Shield marks replies that read as AI-written or come from automated accounts, so you spend your replies on real people. Turn it off any time.
• Profile lens: on any profile, see how that account relates to you.
• Right-click selected text to reply to it or rewrite it. Alt+X opens the composer, Alt+Shift+X opens Xpert.
ALL OF XPERT IN CHROME'S SIDE PANEL
• The whole Xpert app beside the page: Overview, Create, Calendar, Inspiration, Engage, Audience, Analytics and the assistant.
• It follows the tab you're on. On a post: Reply, Quote or Predict. On a profile: how they relate to you and their X-ray. On an article or a video: turn it into posts.
• For you: fresh posts from people you follow, each with a reply drafted in your voice.
YOU SEND EVERYTHING
Xpert puts the draft in X's reply box and you press Reply. By default the draft is copied and you paste it with one keystroke (Cmd+V or Ctrl+V). Turn on One-click fill in the side panel's account menu and it's pasted for you; Chrome asks for that permission once.
WHAT YOU NEED
• An Xpert account with a plan. Every plan starts with a free trial.
• One sign-in, with your X account, covers the side panel and x.com.
• Chrome 116 or later, or another Chromium browser.
PRIVACY
The extension talks only to Xpert's own service. Drafts go to Xpert only when you ask for one. No ads, and your data is never sold. Details: https://xpert.so/privacy#browser-extension
