X-Nova spots posts that are taking off 10–30 minutes before they blow up — a live velocity radar, pre-viral desktop alerts, a work-safe filter, and a 1-tap AI reply you review and post yourself.
X-Nova reads the data your own logged-in X session already loads and does the math locally — no X API, no automation.
For every post in your timeline, X-Nova computes views per hour and acceleration in your browser.
When a watched account or keyword starts accelerating, you get a desktop alert — even with the tab in the background.
One tap turns a rising post into a short, on-topic reply draft using your AI credits.
Review the draft, copy it, and reply yourself. X-Nova never posts for you.
A side panel ranks the fastest-rising posts in your timeline, with badges right on the posts.
Watch accounts or keywords and get pinged the moment one accelerates.
Hide sensitive media, spam/scam and low-velocity noise so your feed stays clean and screen-share friendly.
Draft an on-topic reply to ride a rising post. You review and post it — human in the loop, always.
The interface auto-detects and speaks 16 languages, including English, 中文, 日本語, 한국어, ไทย and Tiếng Việt.
Velocity is computed locally. No auto-posting, no data resale, no ads. See our privacy policy.
