AI YouTube thumbnail designer
The video
Thumbnail designer
AI, words includedGive the video a title of at least 3 characters first. The designer draws from it.
Draws a finished thumbnail, words and all, from your video's title and description. One click, about twelve seconds, in any language or script.
It draws the words as well as the picture
One press returns a finished thumbnail with the words already in it. Leave "Words on the thumbnail" empty and it picks the three or four words that carry the video from what you wrote; fill it in and it sets exactly those. Because the words are drawn by the image model rather than set in one font, it handles scripts the free maker cannot, Devanagari included.
Look at every one before you publish it
Image models get details wrong, lettering included, so nothing is used anywhere until you have seen it. Each takes about twelve seconds, and Generate another draws a new image and spends another. A free account's first one is on us once its channel is connected, and paid plans make 10 to 120 a month.
When the free maker is the better tool
If the exact words and the layout matter, or you expect to rewrite the headline a few times, the free thumbnail maker sets crisp type and re-renders every change for nothing. The designer is for when you would rather hand over the brief than lay the thumbnail out yourself.

This tool also runs over MCP, so Claude, Cursor or another MCP client can use it against your own channel. See the MCP page.
Questions about this tool
Can it make the vertical cover for a Short?
Yes. Choose the Short shape before generating and it draws a 9:16 image instead of a 16:9 one. The two shapes are separate images, so a pair spends two AI thumbnails from the month's balance. Paid plans make 10 to 120 a month.
Does it need an account, and how many do I get?
A free one, with no credit card. Connect your channel and your first AI thumbnail is on us; paid plans make 10 to 120 a month. The free thumbnail maker, which sets type rather than drawing a picture, previews without limit and downloads 2 a day with no account, 4 on a free one.
Where do my channel's numbers come from?
From measurement. Runsheet uses a model to write copy, and every number it reports about your channel is measured, uses medians rather than means and carries its sample size.
Can I run AI YouTube thumbnail designer automatically?
Yes. Every tool here is also exposed as an MCP tool, so Claude, Cursor or anything else that speaks MCP can run it against your own channel. How to connect one is on the MCP page, https://runsheet.buildifyapp.in/mcp.
Do you keep the thumbnail?
Yes, and on purpose: the picture is stored so you can attach it to a video in Runsheet later instead of drawing it again. The title and description you type are sent to Google's Gemini API to produce it.
