The problem
Replies grow accounts on X, but doing them well takes 30–40 minutes a day. Most founders give up after a week.
The approach
An AI copilot that scans your feeds, filters noise, drafts in your voice (learned from your own tweets), and lets you review-then-post or auto-post with human-paced timing.
What shipped
Voice Learning
Drafts replies in your voice by learning from your own past tweets.
Timeline Scanning
Scans your timeline for threads worth replying to.
Human-Paced Timing
Ships replies at human-paced timing so your activity feels natural.
Browser Extension
Built as a browser extension — your X password never leaves your machine.
