Captions.ai is a general-purpose AI video editing app, made by the company that renamed itself from Captions to Mirage in September 2025. It adds subtitles, generates AI avatars, and applies automated edits to video clips. On its Max plan it applies AI edit styles, generates B-roll, music and images, and turns a long video into a batch of post-ready clips. But it cannot schedule posts or plan your week. You still find a scheduling tool and post everything yourself. Its Trustpilot rating is 4.5 stars, though some reviewers report app freezes and credits running out.
VEXI (formerly Social Realtr) is an AI content studio that runs social media for entrepreneurs and creators. You describe what you want and it makes the posts, videos, designs and captions, then schedules and publishes them. Plans start at $199 a month, and every plan starts with a 15-day trial.
The core question is simple: do you want an AI video tool that does one thing, or a complete content engine that does everything? Here is how they compare across every category that matters.
