Yes. Scoring a thumbnail and title costs nothing, and there is no account, no card and no trial. Daily limits keep the service running; nothing is held back behind a paid tier.

Will a high score get me more views?

No tool can promise that, and any that does is selling something. A score tells you whether your packaging has the qualities that tend to earn clicks and hold viewers. Your niche, your audience and your actual video still decide the outcome.

Do I need to upload my video?

Never. The analysis reads the thumbnail image and the title text — the two things a viewer judges before deciding to watch. Your video file stays where it is.

Does it work in my language?

The interface is available in 17 languages, and the analysis follows the language of the title you paste rather than the one the site is set to — so a French title is judged as French.

Why does psychology matter for a thumbnail?

Because a click is a decision made in about a second, on almost no information. Curiosity gaps, unresolved tension and the Zeigarnik effect describe what makes that decision tip — and they are measurable in packaging, which is what the score does.

— 01 / The scoring model

Winning the click is only half the score

Most packaging tools score how clickable something looks. A thumbnail that wins the click and loses the viewer costs you twice — YouTube reads the drop-off and shows the video to fewer people. So every analysis scores both halves, and multiplies them.

Earns the click

Will the impression convert?

Everything visible before the click: how the thumbnail reads at phone size, how hard the title works, and the psychological triggers that make scrolling past uncomfortable.

Survives the click

Will the viewer stay?

What happens after the click: whether the packaging made a promise the video can keep, whether the title and image agree, and whether any of it lands emotionally.

Coherencia título / miniatura
Emoción

Combined, not averaged

The two layers are multiplied rather than averaged, so a weak half cannot hide behind a strong one. A brilliant title on a misleading image scores like what it is.

Clickbait costs you points

El engaño se penaliza siguiendo una curva. Una ligera exageración apenas cuenta; una presentación que engaña se trata como el lastre en que se convierte cuando cae el tiempo de visualización.
