AI Virality Simulator
Upload a product-demo or UGC clip and get an AI virality forecast in about a minute. A panel of audience personas watches it, reacts the way a real comment section would, and a feed-propagation model spreads it cohort to cohort — so you see a virality score, an estimated reach band, a retention curve, and the specific hook fixes that would make it travel further.
It's a directional forecast, not a guarantee — the personas are AI estimates, so treat the score as a relative signal you can act on before you post, not a measured metric.
Face the Virality Jury
Drop a Reel or Short and a panel of ten AI jurors watches it, reacts the way a real comment section would, then hands down a virality score, reach band, and the fixes that make it travel further.

Frequently asked questions
How does the virality simulator work?+
It reads your video (hook, pacing, on-screen text, product), shows it to a panel of AI audience personas who react with watch-through, likes, comments and shares, then runs a feed-propagation model that pushes strong reactions to adjacent audiences. You get a 0–100 virality score, an estimated reach band, a retention curve, and concrete fixes.
Is the virality score accurate?+
It's a directional estimate, not a guarantee. The personas are synthetic, so use the score as a relative signal — compare two edits, test a stronger hook, or sanity-check a concept before posting — rather than as an exact view prediction.
What video should I upload?+
A 15–90 second vertical short-form clip (Instagram Reel or YouTube Short) works best — MP4 or MOV, up to 20MB. Product demos, UGC, and talking-head hooks are ideal.
Is it really free?+
Yes — upload a clip and run it with no sign-up. When you're ready to run campaigns with creators (contracts, escrow in ₹, milestone payments), you can start free on upstageX.
