What is Onyx?
Most X creators post consistently and still can't grow — because X tells you what happened, not why. Onyx is an AI analytics platform for X that breaks down why your content performs. Which hooks land, which formats win, what drives engagement for your audience specifically. Stop reverse-engineering your own best posts. Onyx tells you what worked so you can replicate it, cut what doesn't, and compound growth faster. Know your X. Own your growth.
