Before you hit post on TikTok.
You have a draft with a good idea but a slow start. Upload it, and the report flags that your first line lands at 0:03 instead of 0:00, then hands you three tighter openers to choose from.

Most Tools Predict Virality.
Few Tell You Why.
You film a video, post it, and wait for analytics to tell you it flopped. By then the moment is gone. Many virality tools only look at the first few seconds and hand back a single number, which leaves you guessing what to change.
A useful prediction should point to the exact second your video loses people, explain why, and give you something better to try. That is what you get here, before you post.

Estimate
Overall score (0–100): a quick read on how ready your video is for the platform you picked.
Five sub-scores with reasons: Hook, Pacing, Captions & on-screen text, Audio & voiceover, and Call to action. Each one tells you why it scored the way it did.
Likely drop-off moments: timestamped notes such as "0:04 — the reveal comes too late, viewers have no reason to stay," each with a specific fix.
Estimated retention curve: a model estimate of where attention is likely to dip across the video, clearly marked as an estimate.
Rewritten hooks: two or three new opening lines written for your video and your platform.
Revised script points: a tighter outline you can use when you re-cut or re-film.
Keyframes: stills from the moments the report talks about, so every note lines up with what is on screen.

How the Virality Predictor
Works
1
Upload your video. Any short video up to 60 seconds, straight from your phone or editor.
2
Pick the platform. TikTok, Instagram Reels or YouTube Shorts. Scoring follows what works on the platform you choose.
3
Get your report. The virality predictor watches and listens to the full video, then scores it and writes your fixes.
4
Fix and post. Use the rewritten hook and the timestamped notes to re-cut, then post with more confidence.
Built for TikTok, Reels and
Shorts Creators
Rewritten hooks
Fix and post.
Reels for a small brand.
You run social for a shop and every Reel has to earn its spot. The report shows that your product appears late and your on-screen text is hard to read, so you know exactly what to change before the next shoot.
A Shorts channel that keeps stalling.
Your Shorts get views but people swipe away halfway. The timestamped notes point to a pacing dip in the middle and suggest where to cut, so your next upload holds attention longer.
A Video Hook Analyzer
That Explains Every Score
It watches the whole video. Up to 60 seconds, not just the opening clip, so problems in the middle and ending show up too.
Every score comes with a reason. You see how your hook, pacing, captions, audio and call to action each scored, and why.
Fixes, not just numbers. Timestamped notes, rewritten hooks and revised script points you can use right away.
Scored for your platform. TikTok, Reels and Shorts reward different things, and the report follows the one you picked.
It hears your video. Voiceover, music and timing are part of the analysis, not only the visuals.
Honest about prediction. No tool can promise a viral video. This one shows its reasoning so you can judge each suggestion yourself.
Your video doesn't stay with us. It is deleted after analysis. Only your report and a few keyframes are saved to your account.

FAQ
Can a virality predictor really tell if my video will go viral?
No tool can guarantee that. Views depend on timing, your audience and the platform. What this virality predictor does is check the things you control — your hook, pacing, captions, audio and call to action — and show you where your video is likely to lose people and how to fix it.
Is the retention curve real data?
No. It is an estimate made by the AI from your video's content, and it is always labelled that way. It shows where attention is likely to dip so you know where to look first. Your platform analytics remain the source of real viewer data after you post.
Which platforms does it support?
The virality predictor supports TikTok, Instagram Reels and YouTube Shorts. Pick the platform before you analyze, and the scoring follows what tends to work there.
How long can my video be?
Up to 60 seconds. Longer videos are rejected before analysis, and no credits are used.
What happens to my video after the analysis?
Your video is deleted once the analysis finishes. Only your report and a few keyframes from the moments it mentions are saved to your account, so you can reopen them in My Reports.
Is it free?
The virality predictor includes 1 free analysis for every new account. After that, you can choose a paid plan or buy a one-time credit pack. A credit pack doesn't require a subscription.
How do credits work?
Each video analysis uses 7 credits. You see the cost before you start. If an analysis fails, your credits are returned.
Do I need an account?
Yes. Sign in with Google to run an analysis. Your reports are saved to your account so you can come back to them.
