Free tool

Virality predictor See what grabs attention, and what gets skipped, before you post.

Drop a video or a thumbnail. In seconds you get a score out of 100, how hard the first three seconds hit, the spots people look at first, and where attention drifts, with the fixes to make. Free, no sign-up, nothing to install.

Why people pick this one

How to score a video in three steps

  1. Drop your video or thumbnail in. Straight from your phone or your editor, any format, any shape.
  2. Read the score. The number out of 100, then the three readings: Hook for the first three seconds, Focus for whether one thing owns the frame, Hold for whether attention stays put. Press play to watch the heat move over your video, and see the spots people notice first.
  3. Fix and score again. The tips tell you where it drifts. Tighten the cut, move the face, bolden the title, drop the new version in, and keep the higher score.

Made for the content you actually post

TikToks, Reels and Shorts
The first three seconds decide the scroll. See whether your opening pulls the eye or lets it slide past.
YouTube thumbnails
Does the face win, or the text, or the background? Score two versions and upload the one that gets seen first.
Ads and product videos
Check that the product, the offer and the logo actually get looked at, and how much of the attention each one takes.
Talking-head videos
Find the stretches where attention drifts off you, and cut them or add something to look at.
Two cuts, one winner
Score both edits of the same video and post the one with the stronger hook.

What the score is made of

  • Hook is how hard the first three seconds pull the eye. Strong openings land it in one place at once.
  • Focus is whether there is one clear thing to look at, or a crowd of them fighting for the glance.
  • Hold is whether attention stays where you put it as the video goes on, or scatters and wanders.
  • The score blends the three. The heat view shows the why, second by second, and the tips say what to change.

Questions people ask

Is it really free?

Yes. Thumbnails and the first minute of any video are scored free, with no sign-up. Whole videos up to ten minutes are scored with a free account.

What does the score mean?

It runs from 0 to 100. Above 80 is a scroll-stopper, 65 and up is strong, 50 and up is solid, and below that the opening needs work. The three readings under it tell you which part to fix.

Can it promise my video will go viral?

No tool can promise views. What this one shows is what a viewer's attention does inside your video: where it lands, where it holds, where it drifts. That is the part you can change before you post.

Does it work on vertical videos?

Yes. Vertical, square and widescreen are all scored, and the heat view follows the shape of your video.

What is a good hook score?

75 and above means the eye lands in one place right away. Below 55, open on the face, the product or the biggest movement, and score it again.

Can I check my title or my logo?

Yes. Drag a box over it and you get its share of attention as a percentage. Do it for the title, the face and the product to see who wins.

Why does the first one take a moment?

The first time on a device the tool gets itself ready, which takes a few seconds. After that, thumbnails are instant and videos take a few seconds a minute.

Does it work on a phone?

Yes. Pick a video from your camera roll, and the report card lands in your photos like any other file.
