How generation, quality levels, references, scoring, credits, and saved results work in ThumbSignal.
What does ThumbSignal do?
ThumbSignal creates new YouTube thumbnail images from your video idea. Enter a title or hook, choose a visual direction and image ratio, and optionally add your own reference images. Every completed candidate is saved to your Library for preview and download.
How do I create a YouTube thumbnail?
Open Create, enter your video title or idea, and choose the niche, style, graphic style, ratio, and quality level. You can also add thumbnail text and reference images. ThumbSignal then generates a new, independent thumbnail candidate from that brief.
What do I get for free?
You get one full-resolution watermarked thumbnail in Balanced quality with one reference image. You can preview and download it. Paid plans remove the watermark and unlock up to four references, every quality level, and monthly credits.
What is the difference between Draft, Balanced, and Premium?
Draft is the fastest way to explore a concept. Balanced adds stronger detail for everyday publishing. Premium prioritizes the highest visual detail and finish and can take longer. The three levels cost 1, 2, and 4 credits.
What is a credit?
Credits pay for thumbnail generation and optional scoring. A new Draft, Balanced, or Premium thumbnail costs 1, 2, or 4 credits. Packaging Score costs 1 credit for each thumbnail reviewed, so comparing two thumbnails costs 2 credits.
Are generated thumbnails scored automatically?
No. Create and Score are separate. A score is produced only when you manually request a review, so generation never spends a scoring credit in the background.
What does Packaging Score review?
Packaging Score reviews mobile readability, focal hierarchy, contrast and separation, hook clarity, text economy, emotional signal, and trust or policy risk. Every paid review includes reasons and a three-item priority checklist you can use in your own design workflow.
Is Packaging Score a CTR prediction?
No. It is a structured review of packaging fundamentals, not a CTR prediction or performance guarantee. Use it to structure your decision, then test the thumbnail with your real audience.
Can I compare multiple thumbnails?
Yes. Select or upload up to three thumbnails and review them against the same video title. Each thumbnail costs 1 credit to score. The comparison identifies the highest-scoring option while preserving the full review for every image.
Can I upload my own thumbnail for scoring?
Yes. Score a thumbnail from your Library or upload an existing JPG, PNG, or WebP. Completed reviews are saved in your Library, so the result remains available after a refresh.
Can ThumbSignal edit an existing thumbnail?
No. ThumbSignal creates new thumbnail candidates instead of editing an existing image. Packaging Score recommendations are advisory, so you can apply them in your own design workflow or generate another independent candidate from the same brief.
Where are my thumbnails and score reviews saved?
Completed generations and paid score reviews are saved in your Library. You can reopen and download thumbnails, check whether one has been scored, and revisit completed comparisons after refreshing or signing in again.
How many reference images can I use?
The free thumbnail supports one reference image. Paid plans support up to four references for faces, products, screenshots, poses, or visual direction. References guide a new candidate but do not guarantee an exact copy.
Which image ratios are available?
Choose 16:9 for YouTube, 9:16 for Shorts, Reels, or TikTok, 1:1 for square posts, 4:5 for portrait posts, or 4:3 for classic landscape output.
Do monthly credits roll over?
No. Monthly credits reset each billing cycle. Active subscribers can buy top-up credits, which remain usable while the account has an active paid subscription.
Can I use the thumbnails commercially?
ThumbSignal is intended for creator and business use, but you must review every output and make sure your references and final thumbnail are lawful and yours to use.
What if a request fails?
A confirmed service failure that returns no usable output is eligible for automatic credit restoration where possible. Contact support with the generation or review ID if the balance does not recover.
How do I cancel my subscription?
Open Billing and choose Manage or cancel subscription. The Stripe portal shows the available cancellation timing before you confirm. You can also use the Cancel subscription link in the site footer after signing in.
How do I export or delete my data?
Request account-data export or deletion through support@madebyblankmargin.com. We verify the account before processing the request and may retain records that are required for payment, tax, fraud-prevention, dispute, or legal obligations.
