# ClimbX
> ClimbX is an AI co-pilot for growing on X (Twitter) in your own voice.
It scans the outlier posts breaking out for creators a few steps ahead of you in your niche, learns your voice from your last 100-200 posts, and helps you write posts that land - in your own words. Voice-preserving: AI drafts are edited and approved by the user before anything is posted.
