viral.app vs Virlo: what's the difference?
viral.app runs creator programs: find creators on its marketplace, track their posts and pay them. Virlo is a research tool: AI agents find what is going viral in your niche and turn it into scripts and briefs. Pick viral.app to run creators, Virlo to decide what to make.
A third option is Shortimize: it tracks creators you already work with across six platforms, including X, adds built-in Slack and Discord alerts, and pays creators on every plan from $99 a month.
