Compare Captions vs Mediasaur: faster workflows, better product visualization, and comprehensive creative automation — all in one platform.
Captions.ai (now rebranding to Mirage) specializes in AI video editing, talking avatars like "Selene," and translation features with synced lip movement. But for brands selling physical products, you don't need video editing tools or talking heads—you need realistic product UGC, lifestyle photography, and ad creatives that showcase your actual products.
Mediasaur is built for real products. Upload one product photo → get UGC, product shots, and ad creatives in seconds.
Captions focuses on AI avatars like "Selene" that read scripts and translate voice into 28+ languages. But for ecommerce brands, you need visual UGC—hands holding products, lifestyle scenes, unboxings, and aesthetic product shots. Talking avatars don't showcase your physical products or create the authentic, creator-style content that converts.

Captions is a video editing app with AI features—you need existing footage to edit, or you generate talking avatar videos. Mediasaur starts with your product photo and generates complete UGC content—no editing, no avatars, no existing footage required.

Captions only works with videos—it's an editing tool, not a content generator. For ecommerce brands, you need both photos and videos: PDP images, lifestyle photography, social posts, and video ads. Mediasaur generates the full spectrum of visual content from one product photo.


Original Photo vs. Mediasaur Generation
Captions is mobile app-first, designed for content creators shooting and editing videos on their phones. For ecommerce brands managing multiple SKUs, batch creation, and team workflows, you need a web platform that integrates with Shopify, Amazon, and other ecommerce tools.

Captions' main differentiator is translating voice into 28+ languages with synced lip movement—great for global content creators, but not relevant for product marketing. Ecommerce brands need product visualization, lifestyle scenes, and creative variations that showcase their SKUs. Mediasaur is built specifically for physical product visualization, not video translation.
