Virality Predictor is an AI-powered pre-publish testing tool for short-form video.
Creators, social-media managers, and performance marketers upload a 15-second clip
to our web app and receive — within roughly 30 to 60 seconds — a quantitative read
on how their content is likely to perform on TikTok, Instagram Reels, YouTube
...
Shorts, and similar formats.
WHY WE EXIST
Short-form video is the highest-leverage marketing channel today, but it is also
the most unpredictable. Two clips shot back-to-back with the same creative team,
the same product, and the same hook can perform an order of magnitude apart —
and a creator usually finds out only after they hit "publish" and the algorithm
has already made up its mind. The cost of guessing wrong is real: wasted paid-ad
spend, missed launch windows, and posting fatigue.
Virality Predictor was built to compress that feedback loop from "post and wait
three days" down to under a minute, and to ground the verdict in something more
defensible than gut feel.
WHAT YOU GET
Every upload returns a structured analysis with two layers:
1. Overall metrics
- Viral Potential (0–100): the top-line score, weighted for video duration
according to platform watch-time mechanics
- Hook Score: how strong the opening 3 seconds are at capturing attention
- Hold Rate: predicted completion rate
- Duration: detected length of the clip, in seconds
2. A frame-by-frame attention timeline
For each sampled frame we report five cognitive-engagement signals,
modelled on neuromarketing research:
- Visual Cortex — strength of the visual stimulus (cuts, contrast, motion)
- Auditory Cortex — presence of beats, voiceovers, sound effects
- Language Network — on-screen text and spoken hooks
- Attention Control — suspense, eye contact, novelty
- Focus Drift — the inverse signal: where the viewer is most likely to
scroll away
The timeline is rendered as a synchronized chart that scrubs alongside the
video, so it is immediately obvious which second of a clip is dragging the
overall score down — and therefore where to recut, retitle, or re-shoot.
HOW IT WORKS
Under the hood, we run each clip through a state-of-the-art multimodal AI
model and apply a proprietary scoring layer that translates raw cognitive
signals into platform-relevant metrics. The model and the scoring layer are
constantly evolving as we learn from the videos our users put through the
system.
The user-facing flow is intentionally minimal:
1. Drag a video (up to 50 MB, up to 15 seconds) onto the upload area.
2. Hit "Predict".
3. Read the score; watch the timeline scrub; decide whether to publish,
re-edit, or kill the clip.
No editing required, no plug-in to install, no upload to any social platform.
Nothing is published — the analysis is private to the account that uploaded it.
WHO IT IS FOR
- Performance marketers and paid-ads buyers who want to pretest creatives
before sending them into a meta / TikTok ads auction
- Social-media managers running brand channels who need to vet UGC drops
before scheduling them
- Independent creators who want a second pair of eyes before publishing
- Agencies presenting concept reels to clients and needing an objective
third-party signal to back the recommendation
WHAT MAKES US DIFFERENT
- Speed. Most pre-test tools rely on human panels and take days. Ours
returns a verdict in under a minute.
- Specificity. We score per-second, not just per-clip — you find out
exactly where to cut.
- Honesty. We do not claim to "guarantee virality". Viral Potential is
a probabilistic creative-pretest signal; the user remains in control
of the publishing decision.
- Pay-as-you-go credits. No subscription required. New accounts get a
small free grant; additional credit packs are one-time purchases.
PRICING & ACCESS
Virality Predictor is delivered entirely through our web app at
viralitypredictor.net. You sign in with Google, upload a clip, and pay
in prepaid credits. There is no software to install, no API key to
manage, and no contract to sign. A new user can be from sign-up to first
score in under two minutes.
WHO WE ARE
Virality Predictor is built and run by a small, independent product team.
We do not collect or resell uploaded video content; clips are processed
for analysis and stored only long enough to deliver the result back to
the uploading account. Our day-to-day priorities, in order: keep the
score accurate, keep the latency low, keep the price honest.
