Overview

Captions.ai is an AI-powered video editing app built by Mirage, designed primarily for mobile-first social media creators. Core features include styled auto-caption generation (100+ templates, word-by-word animation), AI Edit for natural language editing commands, eye contact correction, background noise removal, voice cloning, AI Dubbing with lip-sync correction for multi-language content, and AI Twins — personalised avatars generated from the user's likeness. Pro at $9.99/month provides AI editing tools and 200 monthly credits; Max at $24.99/month adds AI Twin, AI Actors, and text-to-video generation at 500 credits/month; Scale at $69.99/month provides 1,400 credits and API access. Credits are consumed by generative AI features and do not roll over. The iOS app is the primary platform — Android and desktop versions lag in features and documented stability.

Key Features

  • Auto-Captions generating stylised animated subtitles with 100+ templates and word-by-word animations
  • AI Edit executing natural language editing commands including pause removal and b-roll insertion
  • Eye Contact Correction adjusting gaze to camera in post-production without re-recording
  • AI Twin creating a personalised avatar from user's likeness that speaks any language with lip sync
  • AI Dubbing and Lipdub translating video audio into multiple languages with synchronised lip movement
  • Voice Cloning replicating user's voice for consistent AI-generated voiceovers across projects

Pros & Cons

Pros

  • AI Twins on Max enable personalised avatar-based video creation where the user's likeness speaks any language with lip-sync — producing multilingual content from a single recording without additional filming or voice talent per language
  • Auto-Captions accuracy cited at 93–99% with 100+ animated style templates enables social media-ready caption styling in one step rather than requiring separate transcription, SRT import, and manual styling in a second tool
  • AI Speech Correction on Pro removes spoken errors with a single tap, eliminating re-takes as a production step for creators recording in non-studio environments where multiple takes create significant time overhead
  • Eye Contact Correction adjusts gaze to camera post-production on all paid plans — a feature that compensates for the off-camera glance that occurs naturally when reading a teleprompter during recording, without requiring reshoots

Cons

  • The iOS app is the primary and most feature-complete platform — Android is limited to a separate Lite plan ($4.99/month, manual editing only) and the desktop web editor lags significantly behind iOS in features and documented stability, making the tool unusable as a primary tool for non-iPhone creators
  • Credits on Max ($24.99/month, 500 credits) and Scale ($69.99/month, 1,400 credits) are consumed by generative AI features and do not roll over monthly — heavy use of AI Twin or AI Dubbing can exhaust the monthly allocation and require purchasing top-up credits at extra cost, creating unpredictable billing
  • User reviews consistently report audio-video sync failures, slow processing, and export failures — particularly on longer videos — making the platform unreliable for creators with deadline-dependent production schedules
  • Customer support response is rated as slow and unhelpful in documented user reviews; no human support tier exists below Enterprise, leaving Pro and Max users dependent on self-service for urgent technical issues

Who It's For

Best For

  • iPhone-first social media creators publishing daily short-form content to TikTok, Instagram Reels, and YouTube Shorts who need AI captions, eye contact correction, and filler word removal without a desktop editing workflow
  • Content creators and marketers on Max ($24.99/month) who need multilingual video distribution from a single recording using AI Twin and AI Dubbing with lip-sync to reach global audiences without per-language re-recording
  • Educators and course creators on Max who need to deliver existing video content in multiple languages without re-recording, using AI Twin dubbing to maintain personal presenter presence in each language
  • Businesses on Scale ($69.99/month) or Enterprise needing API access for programmatic video processing and bulk editing automation in high-volume social media content pipelines

Not Ideal For

  • Windows and Android-primary creators for whom the iOS-first design creates a feature-parity gap — desktop and Android versions lack the full feature set and stability of the iOS app, making Captions.ai a secondary tool rather than a primary production platform
  • Teams requiring predictable, flat-rate monthly billing — the credit-based pricing on Max and Scale creates variable costs that make fixed-budget production planning and per-project cost accounting unreliable
  • Long-form video producers working with files over 30 minutes where processing performance issues and audio sync failures are documented in user reviews
  • Professionals requiring guaranteed customer support response times for production deadline issues — human support below Enterprise tier is not available and documented response quality is inconsistent

Audience Scores

Pro at $9.99/month provides auto-captions with 100+ animated style templates, AI Edit natural language commands, eye contact correction, noise removal, and voice cloning — eliminating the manual post-production steps that consume the most time in daily short-form social media publishing workflows on iOS.

AI Dubbing with lip-sync on Pro enables multi-language video localisation for global campaigns without per-language voiceover talent cost; AI Twins on Max ($24.99/month) allow branded avatar presenters to deliver marketing scripts in any language; credit consumption on Max makes monthly costs variable for high-volume campaign production.

AI Dubbing and AI Twin on Max support multilingual course video delivery from a single recording; AI Speech Correction on Pro removes spoken errors without re-takes; the iOS-first platform design means educators using Windows or Android as primary devices encounter a degraded feature set and reported stability issues on non-iOS platforms.

Scale at $69.99/month provides 1,400 credits and API access for higher-volume agency content production; bulk editing and workflow automation on Enterprise cover multi-client operations; the credit-based pricing model creates unpredictable per-project costs that complicate fixed-fee agency billing structures.

Consider These Instead

When Not To Choose Captions.ai

Choose Veed.io when a browser-based platform with comparable AI captioning, dubbing, and eye contact correction is needed without iOS dependency — Veed.io operates on any device with a browser and provides a more stable team collaboration environment starting at $12/month annual. Choose Descript when transcript-based editing, podcast-to-video workflows, AI voice overdub, and desktop app stability for longer-form content are required — Descript handles long-form video editing more reliably than Captions.ai and includes a desktop app with offline capability. Choose Opus Clip when AI-powered highlight clipping and repurposing of long-form video into short-form social clips is the primary use case — Opus Clip specialises in this workflow at comparable pricing without a credit-based consumption model for core features.
