Core capabilities
Style Match from reference thumbnails
Upload a thumbnail you like and generate a new version that keeps the layout, colors, and composition while changing the content and branding.
Face training for creator identity
Train the model on a few photos of your face so thumbnails can feature you consistently across videos without repeat photoshoots.
Style training for branded output
Train the AI on your own design style to keep future thumbnails visually consistent with your channel or brand.
AI editing for local changes
Adjust specific parts of a thumbnail with AI editing while leaving the rest of the design intact, which is useful for targeted revisions.
Multi-platform output support
Generate thumbnails for multiple platform formats, including YouTube, Shorts, Instagram, and TikTok, using the size that fits the destination.
Common use cases
Fast thumbnail creation from an idea
A solo creator can type a video concept and get a ready-to-test thumbnail quickly, instead of building a design manually in Canva or Photoshop.
Consistent thumbnails featuring the creator
A creator who wants a recognizable on-camera presence can upload a few photos and use the trained face model across future videos.
Recreating a proven thumbnail style
A channel owner can upload a thumbnail style they admire, then generate a new version that follows the same visual structure while using their own topic and branding.
Targeted edits to an existing thumbnail
A team can make small local changes, such as replacing one object or refining a background area, without redoing the full thumbnail.
Cross-platform thumbnail production
Agencies, brands, and short-form creators can produce thumbnails for different platforms while keeping a consistent look across formats.
