Every Feature You Can Explore Inside The Dashboard
Thumbium provides the core tools you need to create attractive thumbnails quickly, even if you have no prior design experience.
✅ Prompt to Thumbnail:
Describe your thumbnail idea in a few words, and Thumbium turns it into a complete image within seconds. You can explain the scene, subject, mood, or message using everyday language.
✅ Style, Type & Layout Presets:
Choose the visual direction that matches your video, including the art style, image type, and overall layout. These presets help you create a click-friendly design without arranging every element manually.
✅ YouTube and Shorts Formats:
Create thumbnails for standard YouTube videos in 16:9 or vertical Shorts covers in 9:16. Thumbium automatically prepares the image in the correct dimensions for your selected format.
✅ Reference Photos:
Upload your face, a product image, or a background when you want the design to include something specific. The AI uses those photos to create a fresh scene around your real subject.
✅ Up to Four Versions Per Request:
Generate as many as four different variations from a single idea. This gives you several options to compare, making it easier to choose the thumbnail with the strongest visual appeal.
✅ Use Your Own OpenAI API Key:
Thumbium connects to your personal OpenAI key to generate images. You control how much you generate and pay OpenAI directly based on your actual usage.
✅ Put Yourself in Every Thumbnail:
Upload one selfie and place yourself in almost any setting, such as a gaming room, a cruise ship, a restaurant, a city, or a futuristic scene. Thumbium removes the original background, inserts you into the new environment, and blends the lighting and shadows for a natural result.
✅ Put Your Face on Every Video:
Using your own image across your thumbnails can give your channel a more personal and recognizable identity. Regular viewers can spot your content more easily while browsing their feeds.
✅ Show Real Products:
Add an actual product photo to your thumbnail and present it in a setting that fits your content. This works especially well for product reviews, unboxing videos, tutorials, and promotional campaigns.
✅ Skip the Photoshop Work:
Thumbium handles subject cutouts, background removal, image placement, and scene blending automatically. You do not need to work with layers, masks, or complicated editing software.
✅ Mix and Match Subjects and Backgrounds:
Combine almost any person, item, and background to create scenes that would be expensive or difficult to photograph. This gives you more creative freedom when planning thumbnails for different video topics.
