YouTube Thumbnails
Ask Seba for a thumbnail and it generates a branded 16:9 cover from your reference photo and video title — big face, a 3-5 word hook, two-colour contrast — built on high-CTR principles and returned ready to upload. Billed per run.
A cover built to be clicked, not just look nice
Built on high-CTR rules
Face filling 30-50% of the frame, a 3-5 word hook, two dominant colours and one clear focal element — the principles top creators use, applied every time.
Generated from your photo
Send a clear headshot and Seba uses it as the image input, recreating you in the cover with the expression and lighting you want to reuse across videos.
You approve the brief first
Seba returns a brief — composition, hook text, palette, supporting element, tone — and waits. Tweak anything before it spends a credit generating.
Just send a title
No design tool. Give a title (or a topic and Seba suggests three), pick a tone, and the 1280×720 thumbnail comes back to the chat, billed per run.
The thumbnail principles applied
The high-CTR rules a pro applies to every cover, in one pass.
- Face fills 30-50% of the frame and stays readable at small sizes
- 3 to 5 words of large text maximum (6 only if essential)
- Two dominant colours — brand primary plus one high-contrast accent
- One clear focal element besides the face — logo, bold number, arrow or prop
- High contrast between face, text and background
- Text as a hook phrase, not a sentence — “Don’t do this”, not a full line
- No small text and nothing bottom-right where the watch-time icon sits
- 16:9 at 1280×720, sharp and readable at 320px wide
- A consistent thumbnail style recommended across your videos

Frequently asked questions
What do I get back?+
A generated 1280×720 (16:9) thumbnail with your face, hook text and brand colours — preceded by a brief you approve first. It arrives in the Telegram chat, ready to upload.
Does Seba upload it to YouTube for me?+
No. Seba generates the thumbnail and hands it to you in the chat. Uploading it to your video and managing your YouTube channel is something you do yourself.
Do I need to send a photo?+
Yes — a clear headshot works best, since Seba uses it as the image input to recreate you in the cover. Pick an expression and lighting you can reuse across videos.
Can the hook text be in my language?+
Yes. Seba writes the text in the language you use, keeps it to 3-5 words (6 max), and never uses em dashes — sized to stay readable at small thumbnail scale.
How much does a thumbnail cost?+
The brief is part of the run; generating the image is a paid Aporto generation, billed once on success. Seba shows the credit cost before it generates. Start free with welcome credits.
