CompoundX

Find worthwhile X conversations, draft in the post's language, and save posts. Pro required.

CompoundX helps you decide where a reply is worth your time while you browse X. It adds a compact opportunity bar to supported posts in your timeline. The bar combines available public signals into an estimated reach, reply position, action window, and priority. Estimates are labeled as estimates, and missing signals are shown as unavailable instead of being treated as zero. When you choose to reply, CompoundX can draft several angles in the source post's language. You review and edit every draft before anything is placed into X. Safe mode copies text to your clipboard by default; convenience mode can fill the active composer when you explicitly request it. CompoundX does not publish a reply without your action. You can also save useful public posts to your CompoundX library and continue working with them in your account. The side panel brings together your current growth stage, today's action window, recent outcomes, settings, and diagnostics. Core features require an active CompoundX Pro subscription. The current introductory price is US$9.90 per month, regularly US$19.90 per month. Pricing may change; the checkout page always shows the applicable price before purchase. What CompoundX does: - identifies higher-value reply opportunities in supported X timelines; - labels estimates and missing data clearly; - drafts replies in the source post's language; - copies or, when enabled, fills text only after your explicit action; - saves selected public posts to your CompoundX account; - shows account, preference, and outcome information in the Chrome side panel.
