What is Captions?
Captions is an AI‑powered creative studio that turns raw video footage into fully‑edited, stylized videos in minutes. It uses AI to automatically cut scenes, overlay B‑roll, apply pacing, and style clips so results look like they were edited by a professional, then lets users export them directly to social platforms. The tool also auto‑generates captions and subtitles, making it easier to post short‑form and long‑form content with on‑screen text that syncs to the audio.
A key pillar of Captions is its avatar‑based video creation: users can create or reuse an AI actor from a selfie or existing footage, then generate talking‑head videos from a script or audio. These avatars can be reused across multiple videos with different outfits, backgrounds, and product placements, letting brands and creators scale content without reshoots. The platform is available both as a mobile app (iOS) and a web interface, so creators can edit on‑device or in the browser.
Captions is designed for content creators, marketers, educators, and small businesses that want to publish frequent short‑form and long‑form videos without deep editing skills. Social‑media teams can quickly repurpose interviews, webinars, and talking‑head clips into polished reels, Shorts, and posts, while solopreneurs can build a catalog of avatar‑driven videos for tutorials, ads, and explainers. The API layer also makes it suitable for developers who want to integrate AI‑driven video editing, captioning, and translation into their own products or workflows.
Captions pricing
Pricing model: Free
Captions offers a tiered plan structure with Basic, Pro, Max, and Scale subscriptions available on both iOS and web. Each plan includes a certain number of AI video generation credits or monthly minutes, with higher tiers unlocking more minutes, faster processing, and access to premium features such as advanced avatars and higher‑resolution exports. The platform uses a credit‑based system for AI‑generated videos, where more complex or longer clips consume more credits, and the exact allotment and price per tier are detailed in the subscriptions section of the Captions help center. Free trials or limited‑free usage may be available to new users, but full commercial usage requires an active paid plan.

Frequently asked questions about Captions
What does Captions actually do with my video?
Captions takes your raw video and uses AI to automatically cut scenes, apply pacing, and overlay B‑roll or other visuals to create a polished, stylized edit. It can also generate on‑screen captions or subtitles that sync to the audio, so you get a share‑ready video without manually trimming or titling it yourself.
Do I need to know how to edit video to use Captions?
No; Captions is designed for non‑editors, so you only need to upload raw footage or provide a script or audio, then let the AI handle cutting, styling, and captioning. The interface is optimized for creators who want professional‑looking video without deep editing skills or timelines.
Can I reuse the same AI actor across different videos?
Yes; once you create or train an AI actor from a selfie or reference footage, you can reuse that same avatar in multiple videos. You can change outfits, backgrounds, and product placements per video while keeping the actor visually consistent.
Which platforms can I publish Captions‑edited videos to?
Captions‑edited videos are optimized for short‑form and long‑form social platforms such as Instagram Reels, TikTok, YouTube Shorts, and similar formats. You can export the finished video to your device or cloud storage and upload it directly to your preferred platforms.
Does Captions work on mobile and desktop?
Yes; Captions offers an iOS app that lets you edit, subtitle, dub, and publish videos straight from your iPhone or iPad, and a web version that runs in your browser for creating realistic talking‑video from a script or audio, plus managing longer projects online.
Can I generate captions in multiple languages?
Captions supports generating captions and subtitles from audio, and the platform can translate and render those captions into multiple languages, depending on your plan and selected language options. This helps reach international audiences without manually re‑typing each subtitle line.
Is there an API for integrating Captions into my own apps?
Yes; Captions and Mirage provide an API at api.mirage.app that lets developers integrate AI video captioning, generation, and translation into their own products or workflows. This is useful if you want to add AI‑driven video editing and captioning to custom platforms or internal tools.
How are AI usage credits calculated in Captions?
Captions uses a credit system where generating AI videos with the Mirage model consumes credits based on complexity, length, and resolution. Higher‑tier plans give more credits or minutes per month, and detailed breakdowns of credit usage per model call are explained in the AI usage section of the help center.
Can I edit the AI‑generated captions after they’re created?
Yes; once Captions auto‑generates captions or subtitles, you can manually edit the text, adjust timing, or restyle the on‑screen titles to match your brand or correct any inaccuracies before exporting the final video.
Who is Captions best suited for?
Captions is best for creators, marketers, educators, and small businesses that want to publish frequent short‑form and long‑form videos with minimal editing time. It is especially useful for social‑media teams, solopreneurs, and anyone who needs to scale content using AI avatars and automated edits instead of traditional production.
