CompoundX is an AI-powered X (Twitter) growth tool focused on reply-driven growth. Find valuable conversations, evaluate reply opportunities, and draft contextual replies for your review.
Original posts establish your point of view. Useful replies bring those ideas into relevant conversations that are already happening. CompoundX helps decide where the work is worthwhile before it helps with the writing.
See how relevance, timing, conversation saturation, and data confidence shape a reply decision.

Read the complete guide →Not another dashboard. Clear decisions, drafts, and source labels appear where you already do the work.
Use interaction velocity, conversation stage, and position to estimate reach and the action window, then focus on better opportunities.
Express the idea in the language that feels natural. CompoundX drafts in the source post language; you review tone, facts, and boundaries.
Turn completed actions and available results into a daily settlement that separates measurements, estimates, and unavailable data.
CompoundX stays close to the native X workflow and reduces the cost of bouncing between the timeline and external tools.
A lightweight marker appears beside each post that can be analyzed. Your full timeline stays intact with one added decision layer.

Safe copy by default · Optional convenient modeReview and publish manually. Later data enters the side panel and daily settlement with its source attached.
Human confirmation · No automated engagementVisible X page data is labeled as measured, model output as estimated, and unavailable data is never dressed up as certainty.
