Home › Help Center › Compare › ACE AI Spark vs Captions (Mirage)

Captions started as a mobile captioning and editing app and, as Mirage, now generates fully synthetic AI video and presenters from an audio track. ACE AI Spark shares the goal of creator-style video without a camera, but builds it around a brief, a persistent AI creator, and a publisher for six social networks.

Where Captions is strong

Fast, phone-first video with excellent captioning and editing. If you record on your phone and want polished cuts and subtitles in minutes, it is a strong fit.

Where ACE AI Spark is different

You bring the idea, not the recording. ACE plans the content from a brief and renders it; no audio to record first.
The creator persists. A digital influencer keeps its face, voice and style across every post.
Publishing built in. Calendar, six-network scheduler, media library and analytics in the same product.
Clear pricing. One credit is one cent, a free plan exists, and the cost is shown before each generation.

When to choose which

Choose Captions for fast phone-first editing, captions and AI presenters from your own audio. Choose ACE AI Spark to go from a brief to published posts with a consistent AI creator.
