Captions started as, and remains primarily, an AI video editing tool: automated professional-style cuts from raw footage, B-roll insertion, stylised captions in 100+ languages, and a chat-based prompt editor. Its AI avatar feature — digital twins and "AI Actors," rendered through its Mirage Avatar X model — is a real, verified capability, but it sits alongside editing tools rather than being the whole product the way it is for Creatify or Arcads.
Sellable does a narrower, more specific job: upload a product photo, generate studio shots, lifestyle scenes, on-model fashion photography, and short UGC-style video from that same image.
The overlap is real but partial — Captions can produce an avatar-led UGC-style ad if you build the workflow yourself; Sellable produces product-led content without an avatar or raw-footage editing step at all.
Captions outputs: edited video from your raw footage (automated cuts, B-roll, captions), plus AI-avatar/digital-twin video through its Mirage Avatar X model, in 100+ languages.
Sellable outputs: studio and lifestyle product photography, on-model fashion shots, and short UGC-style product video generated from the same uploaded image, with no editing or avatar step involved.
If you already have raw footage and want it edited well, or want an avatar to deliver a script, Captions covers both. If you have a product photo and need images plus video without a filming or editing step, Sellable covers that instead.
Captions is ideal for:
- Creators and businesses with existing raw footage that needs professional-style automated editing
- Teams that want an AI avatar/digital-twin option alongside general editing tools
- Multi-vertical use (beauty, fitness, education, real estate, ecommerce) rather than ecommerce-only workflows
Sellable is ideal for:
- Ecommerce sellers who need studio and lifestyle product photography for listings
- Brands that want on-model fashion photography alongside product video
- Teams generating photography and video from a single product photo with no filming or editing step

Captions for creators and businesses who need general-purpose AI video editing, with an avatar option available when a script-led video is useful.
Sellable for ecommerce brands whose primary need is product photography, with UGC-style video generated from the same upload, and no raw-footage editing or avatar step required.
No. Captions is a video editing and avatar platform — it doesn't produce standalone studio or lifestyle product photography for listings.
No — it's a general-purpose tool used across many verticals (beauty, fitness, education, real estate, ecommerce among them), not an ecommerce-ad specialist like Creatify. You can build a UGC-ad workflow in it, but it isn't the default use case.
It's Captions' AI avatar model, which handles voice, micro-expressions, eye contact, and body language together to produce a digital-twin or AI-actor performance — available from the Max tier ($24.99/month) up.
Both are possible — you can edit existing raw footage automatically, or generate avatar-led video without filming anything, using the AI Actors/digital twin feature.
