Which should you choose?

Captions

Creators and DTC/social sellers making short-form, captioned, UGC-style video ads quickly.

Perpetua

Established Amazon and Walmart brands spending significantly on ads who want listing copy and campaign management in one platform.

Captions

Pros

  • Fast idea-to-finished workflow with no editing skills needed
  • AI UGC actors and styles well suited to short-form social ads
  • Free version plus transparent paid pricing

Cons

  • Credit-based plans cap how many videos you can make
  • Displayed pricing reflects iOS plans only
  • Less control than a manual pro editor for fine-grained edits

Perpetua

Pros

  • Unique full-funnel alignment: listing copy and ad spend share the same keyword performance data
  • Strong fit for mid-market and enterprise Amazon brands running meaningful ad budgets
  • Walmart and TikTok Shop coverage extends value beyond Amazon for multi-marketplace sellers

Cons

  • Custom pricing with no published rates — typically practical only for brands spending $10k+/mo on ads
  • Listing optimization is secondary to ad campaign management; pure copywriting tools offer more on the content side
  • Overkill and poor ROI for sellers not actively running paid campaigns
