X-Nova – Pre-Viral Radar for X

Spot tweets accelerating 10–30 min before they blow up. Live velocity radar, watch-list alerts, work-safe filter & 1-tap AI reply.

X-Nova — catch the wave before it peaks. Most tools tell you a post went viral after it already blew up. X-Nova watches the rate of change: it computes every post's view velocity (views/hour) and acceleration right in your browser, so you can spot posts taking off 10–30 minutes before they peak. WHAT YOU GET • Live velocity radar — a side panel ranks the fastest-rising posts in your timeline, with badges right on the posts. • Watch-list alerts — add accounts or keywords and get a desktop alert the moment one starts accelerating, even when the tab is in the background. • Work-safe filter — hide sensitive media, spam/scam and low-velocity noise to keep your feed clean and screen-share friendly. • 1-tap AI reply — draft a short, on-topic reply to ride a rising post. You review and post it yourself — X-Nova never posts for you. • 16 languages, auto-detected. PRIVACY FIRST Velocity is computed locally from the data your own X session already loads. X-Nova does not use X's API, does not auto-post, does not sell your data, and shows no ads. The AI reply feature sends only the selected post's text to our backend to generate your draft — see our privacy policy for details. Free includes the velocity radar and basic alerts. Pro unlocks acceleration alerts, filters, and a monthly batch of AI reply credits.
