Everything in Thumbnail Agent
Faces, references, styles and formats. Direct the thumbnail you have in mind instead of hoping the AI guesses it.

Frequently asked questions
Does it work like a thumbnail designer?
Yes. Thumbnail Agent is an AI designer you can talk to. Share your idea and references, discuss the direction, review a black-and-white sketch and ask for changes before the final image. When you attach a video, it guides both the sketch and the final thumbnail.
Can I use it on Telegram or Discord?
Yes. Connect your Adventure AI account once from the Thumbnail Agent page, then chat with your designer in a Telegram or Discord direct message. Send text, voice notes, photos, a video or a PDF. Each thumbnail uses the same credits and also lands in your Adventure AI gallery.
How do I make a thumbnail with AI?
Open Thumbnail Agent and describe your video or upload your content. The agent helps you develop an idea, offers a sketch and uses your feedback to refine it before generating the final thumbnail. You can also tag saved people with @name and reference images with #name.
Can I put my own face in the thumbnail?
Yes. Save a person with a few photos, then mention them with @name in your prompt. You can include up to 2 people in the same thumbnail and describe where each one should appear.
Can I make a thumbnail from a PDF or a video?
Yes. Upload a PDF of up to 40 pages or a video of up to 100 MB on the website. The agent uses your content to develop the idea. A prepared version of your video, with audio, also goes into the sketch and final generation so both follow your story.
Can I use a YouTube video as a reference?
Yes. Paste a YouTube link into the prompt and the video thumbnail is added as a #YouTube reference. You can also attach or paste your own images, or reuse any of your results as a reference.
Which sizes can I create?
16:9 for regular YouTube videos and 9:16 for Shorts, Reels and TikTok. Choose the format before you generate.
Can I create my own style?
Yes. Add up to 5 reference thumbnails, give the style a name and select it again whenever you need it. Custom styles are saved in the browser where you created them.
How many thumbnails can I generate at once?
Up to 4 per prompt. You also do not have to wait: keep sending new prompts while the earlier ones are still generating.
What can I do after generating?
Download the image, use it as the reference for a new version, or send it to Upscaler, Relight, Skin Enhancer or Video. For a layered PSD, open the image in Layers Studio.
Can I generate a thumbnail in layers?
Layered generation is coming soon. You will be able to choose a thumbnail with separate, editable layers, so you can refine individual elements after generation. Today, you can open a generated image in Layers Studio to work on it and export a layered PSD.
Do I need a paid plan?
Thumbnail Agent is part of the Adventure AI plans, and each thumbnail uses credits from your balance. New here? Try Pro for 3 days for $1. Check Pricing to see what each plan includes.
