Captions
Mirage · Writing · Video
Captions is an AI video editor and generator built by Mirage, a New York company that also builds the Mirage foundation models behind the app. You upload footage or a prompt, and Captions cuts scenes, adds B-roll, music and styled captions, or generates new talking-head video with an AI Twin. It runs on iOS, Android and the web, and most of its advanced AI work sits behind a paid plan.

About Captions
What Is Captions
Captions started as a captioning app and grew into a full AI video studio. The core idea is simple. You bring raw footage, a script or even just a selfie, and the app handles the slow parts of editing for you. That means auto-transcription, scene cuts, sound effects, eye-contact correction and dubbing into 30+ languages, all without a timeline or a single keyframe. That's the pitch, anyway.
It's aimed at people who need video to grow something, not people who enjoy editing for its own sake. Content creators, podcasters, small businesses, marketers and agencies all show up in the official solutions pages, along with niche verticals like real estate, fitness and legal. If your job is publishing video regularly, Captions is built for that cadence rather than for one-off cinematic projects.
The limits are worth knowing before you commit. Credits drive every generative feature, so heavy use of AI avatars or text-to-video drains your monthly allowance fast. The free plan watermarks exports and caps you to a single caption template. And vendor benchmarks and marketing language aside, the app's output quality still depends on what you feed it, which is true of every AI video tool right now.
Getting Started
- Sign up at captions.ai or install the app from the App Store or Google Play. Google, Apple, email and phone are all supported.
- Start a project by uploading footage, recording in the app, or typing a text prompt to generate a video from scratch.
- Pick a style or open the chat-based editor. Ask for cuts, captions, B-roll or music in plain language, or apply a one-tap AI Edit preset to restyle the whole clip.
- Review the result on the timeline. Fix spelling, retime captions, swap a clip or adjust voices before you publish.
- Export or post directly to TikTok, Instagram, YouTube and other platforms, or download the file with captions burned in.

Key features
AI Edit and the Chat-Based Editor
AI Edit applies a chosen style to your whole video at once: it cuts scenes, overlays B-roll, adds transitions and music, then leaves the result on a timeline you can still tweak. If something looks off, the chat-based editor takes plain-language instructions like "trim the pauses" or "swap the intro clip." For anyone who has stared down a Premiere timeline, that prompt-driven approach is the whole point of the product. It's not subtle. That's the appeal.
Auto-Captions in 100+ Languages
Captions is what the company was named for, and it shows. The app transcribes your audio, syncs the text to the timeline and lets you restyle it with over 100 templates. Font, color, size, animation and placement are all adjustable. Captions generate in more than 100 languages, which is why so many creators use it just for subtitle work. Downloading the transcript is supported too, so you can reuse the text elsewhere.
AI Twins and AI Actors
An AI Twin is a digital clone built from a photo or short clip of you, and it can deliver new scripts without another recording session. If you'd rather not appear at all, the AI Actors library offers generated presenters whose outfits, backgrounds and delivery you can change between videos. The company says avatars are rendered as complete performances with audio, video and visuals together, which is what gives them natural lip-sync.
Dubbing and Translation
This feature translates a finished video into 30+ languages and dubs it with a cloned version of the original speaker's voice, matching lip movement to the new audio. Ever watched a badly dubbed clip and given up halfway? This solves that. For creators with global audiences, it beats publishing subtitles alone because the delivery stays natural rather than feeling read. It's one of the clearest reasons to pick this AI video editor over a straight captioning tool.
One-Tap Quick Fixes
Beyond the big AI features, Captions ships a set of small corrections that normally eat editing time. Eye-contact correction redirects a speaker's gaze to the camera even if they were reading a teleprompter. Noise reduction, filler-word and pause removal, background removal and auto-zooms all run from the same interface. Individually these are minor. Together they remove most of the tedious cleanup work.
Credit-Based Generative AI
Credits power every generative feature, from images and music to voiceovers and full AI Edits. Plans allot different amounts per month, and unused credits roll over up to three times your monthly allowance. Knowing how quickly Prompt to Video and avatars spend credits matters more than any single feature when you're weighing Captions pricing against a tier. Marketing videos that lean hard on generation will burn through a Max plan quickly.
Pros and cons
Pros
- Captioning is genuinely strong, with 100+ languages, 100+ style templates and transcript downloads built in.
- AI Edit and the chat editor cut a full video in one pass, so people with no editing background can still ship finished clips.
- AI Twin, AI actors and voice-cloned dubbing cover workflows that would otherwise need a camera, a cast and a recording booth.
- Direct publishing to TikTok, Instagram, YouTube and more removes the export-and-upload shuffle.
Cons
- The free plan watermarks exports and allows only one caption template, so the free tier is closer to a trial than a working setup.
- Generative features run on credits, and avatar or text-to-video work consumes them quickly, so costs can climb for high-volume teams.
- Fine-grained manual editing is thinner than in a traditional NLE, which matters if you want frame-accurate control rather than prompt-driven changes.
Frequently asked questions
It's an AI video editor for quickly producing finished short-form video. As a video editing app, Captions handles auto-captioning, AI Edit, voice dubbing and avatar generation in one place, so you don't juggle separate tools for each job.
