Score thumbnails before CTR tells you
Braiv scores any thumbnail out of 100 on five pillars: Topic Match, Clarity, Standout, Curiosity and Emotion. It tells you what works, what does not and how to improve it, then Fix builds the better version in one click.

What this does
What scoring gives you
Predict click-through potential before you hit publish. Score any YouTube thumbnail out of 100 on Topic Match, Clarity, Standout, Curiosity and Emotion, get specific feedback for each, and fix weak designs in one click.
-
A reason to pick one option
A score out of 100 before publish, not a guess from last week’s analytics.
-
Specific, actionable feedback
Strengths, a critique and how to improve, for each of the five pillars. Not a vague “make it pop.”
-
Fixes without a redesign
Hit Fix and Braiv builds an improved version from the feedback, then rescore before anything goes live.
The five pillars
What Braiv checks on every thumbnail
Each pillar is scored out of 10 and rolled into an overall score out of 100, with strengths, a critique and a concrete way to improve.
Clarity
Can you read the subject and the text when it is a few centimetres wide on a phone?
Standout
Does it pop next to everything else in the feed, on light and dark YouTube?
Curiosity
Does it open a question the viewer needs answered by clicking?
Emotion
Is there a face, an expression or a feeling that pulls the click?
Fix
From critique to a better thumbnail in one click
Fix reads the feedback and generates an improved version, tagged as a Score fix in your thumbnail library so you can compare it with the original.
Targets the weak pillars
Fix works from the critique, so it improves what scored low instead of starting over.
Rescore before you ship
Score the fixed version too, so you publish the strongest option rather than the newest.
Localize the winner
Translate the overlay text for other markets once, after the master is right.

Why you should not wait for the CTR report
Click-through is a lagging signal. By the time YouTube tells you a thumbnail underperformed, the upload has already burned its first wave of impressions.
Scoring flips that order. You get a structured read on Topic Match, Clarity, Standout, Curiosity and Emotion while the video is still in draft — so the decision happens before publish, not after a weak week in Analytics.
What “good” means at feed size
A thumbnail that looks sharp in a full-screen design tool often fails when it is a few centimeters wide on a phone. Braiv evaluates the image the way the feed will show it: contrast against YouTube’s chrome, text that still reads at small sizes, and a subject that remains clear when half the detail disappears.
Title match matters as much as polish. An image that promises a different story than the title creates confusion, not curiosity — and confused scrollers do not click.
Feedback you can act on
A score without a reason is theater. Braiv returns specific recommendations — boost contrast, enlarge text, simplify the layout, align the subject with the title — so the next edit has a target instead of a vibe.
That feedback is what makes A/B choices useful: you are comparing scored options with known weaknesses, not two gut feelings.
From score to fix without a redesign
Fix works from the score. When you want to skip the score and rebuild an image you already have, 1-click Optimize turns it into a high-CTR thumbnail with an overlay written from the video, and you rescore. When you need a new concept entirely, go back to Zero-prompt Thumbnails, with your Character references if the Emotion pillar needs a face. For markets beyond English, translate overlay text so the scored package matches each dubbed title.

Auto Packaging
Auto Packaging is a step in the upload flow. Pick a title style, a description type and a thumbnail mode, and Braiv builds all three from the video as soon as the transcript is ready, for one upload or a whole batch.

Zero-prompt Thumbnails
Braiv watches the whole video, works out what it is really about and designs the thumbnail for you. It pulls strong frames straight from the footage or generates its own visuals, with no prompt, no Photoshop and no rewatching.

Character reference
Train a Character reference once from at least three clear photos. Then choose up to three characters for any Creative thumbnail and Braiv puts the real you in the scene, with the expression the story needs, on every upload.

Frequently asked questions
What does the thumbnail score measure?
Five pillars, each out of 10: Topic Match (does the image deliver the title), Clarity (is it readable at feed size), Standout (does it pop in the feed), Curiosity (does it make you want to know more) and Emotion (is there a face or feeling that pulls the click). Together they make an overall score out of 100. The point is not a vanity number, it is a structured reason to choose one option over another before publish.
Can I score a thumbnail that is already on YouTube?
Yes. Upload any thumbnail, including one already live on your channel, and score it. That is the fastest way to find uploads worth re-packaging.
Can I score thumbnails I already uploaded?
Yes. Connect a channel and scoring runs across published videos, so you can find underperformers in the back catalog and prioritize replacements where a new thumbnail is worth the credits.
Does a high score guarantee high CTR?
No score can promise click-through. Audience, niche, and title still matter. Scoring reduces the chance you ship a thumbnail that fails the basics — unreadable text, muddled contrast, or an image that fights the title — before the analytics report arrives a week later.
How do I fix a low-scoring thumbnail?
Hit Fix and Braiv builds a new version from the critique on the weak pillars. Or use 1-click Optimize, which rebuilds any image as a high-CTR thumbnail with an overlay headline written from the video, then rescore. Generation and scoring live in the same Braiv Thumbnails pipeline.
Can I compare multiple thumbnail variations?
Yes. Generate or upload several options, score each one, and pick the strongest objectively rather than debating taste in a Slack thread. That is the usual workflow before a launch or a back-catalog refresh.
Does scoring use AI Credits?
Scoring and fixes draw on the shared AI Credit balance with the rest of Braiv Thumbnails. Business includes enough credits for up to 270 thumbnail generations a month, with unused credits rolling over — full detail on pricing.
