Try Captions.ai Now
The fastest way to add auto-captions and AI tools to your videos on iOS and Android.
Overview
Captions.ai is the go-to AI video tool for creators who publish on TikTok, Instagram Reels, and YouTube Shorts. What started in 2021 as a straightforward automatic captioning app for iPhone has since evolved into a comprehensive AI-powered video production platform trusted by millions of mobile-first creators around the world. If you produce short-form video content regularly, Captions.ai is one of the few tools that can meaningfully cut your editing time while also making your videos look more polished and professional.
The platform's growth has been driven by two genuinely unique features that set it apart from every competitor: eye contact correction — which uses computer vision to make it appear that you are always looking directly into the camera, even when you are reading from notes or a script — and industry-leading automatic captions that achieve over 98% accuracy across 28 languages. Together, these two features solve two of the most common pain points for solo creators who shoot on their phone.
Captions.ai is built exclusively for mobile (iOS and Android). It is not a desktop editor, and it does not try to compete with professional non-linear editors like Premiere Pro or DaVinci Resolve. Instead, it occupies a specific and valuable niche: helping individual creators get from raw footage to a publish-ready vertical video in minutes, entirely from their phone. For that use case, it is currently unmatched.
Key Features
Auto Captions
AI-generated captions with over 98% accuracy in 28 languages, featuring word-by-word animated highlighting. Choose from dozens of caption styles, fonts, colors, and animations designed specifically for social media formats. Captions are synced precisely to your speech and can be edited directly on-screen with a tap.
Eye Contact Correction
Captions.ai's flagship AI feature subtly corrects your gaze so you always appear to be looking directly at the camera, even when you are glancing at a script, teleprompter, or notes. The effect is natural, undetectable, and gives every video a significantly more engaging, connected feel. No other mobile video app offers this at this level of quality.
AI Dubbing
Translate and dub your videos into 28 languages while preserving your original voice, accent, and vocal characteristics. The AI lip-syncs the translated audio to match your mouth movements. This feature is a game-changer for creators looking to reach international audiences without re-recording content or hiring voice actors.
Creator Studio
A suite of production tools built for mobile creators: AI-powered green screen with background removal, virtual background replacement, a built-in teleprompter for smooth on-camera delivery, and silent filler word removal that automatically cuts out ums, ahs, and awkward pauses from your recordings without manual editing.
Auto-Reframe
Automatically converts horizontal 16:9 footage to vertical 9:16 format optimized for TikTok, Instagram Reels, and YouTube Shorts. The AI detects the main subject and intelligently reframes the crop throughout the video so the speaker always remains centered. Eliminates the tedious manual process of re-editing landscape videos for vertical platforms.
AI Script & Prompter
Generate video scripts on any topic directly inside the app using built-in AI, then display them as a smooth scrolling teleprompter during recording. You can adjust scroll speed to match your natural pace, ensuring confident, fluent delivery without memorization. The result synergizes perfectly with the eye contact correction feature, masking teleprompter use completely.
Pros & Cons

Pricing Plans
Captions.ai uses a straightforward tiered subscription model billed monthly or annually (annual billing offers approximately 30% savings). All plans are available on both iOS and Android.
| Plan | Price | Exports/Month | Key Features |
|---|---|---|---|
| Free | $0 | Limited exports, watermark | Auto captions (basic), filler word removal, standard caption styles, 720p export |
| Pro | $19.99/mo | Unlimited, no watermark | All caption styles, eye contact correction, auto-reframe, AI dubbing (5 videos/mo), 1080p export |
| Creator | $29.99/mo | Unlimited, no watermark | All Pro features + unlimited AI dubbing, AI script generator, green screen, priority export queue, 4K export |
The Pro plan at $19.99/month is the sweet spot for most creators who publish regularly to TikTok or Instagram. The Creator plan at $29.99/month is worth it if you rely on AI dubbing for multilingual distribution or use the AI script generator frequently. The free tier works well for occasional use or for testing caption accuracy before committing.
How It Compares
Captions.ai vs CapCut AI
CapCut is Captions.ai's closest competitor in the mobile short-form video space. CapCut has a broader editing feature set — including more transition effects, text templates, and a desktop web editor — but its auto-caption accuracy is noticeably lower than Captions.ai, especially for non-English content. Crucially, CapCut does not offer eye contact correction. Captions.ai wins on AI depth; CapCut wins on editing breadth. Many serious creators use both: CapCut for general editing and Captions.ai for captions and eye contact polish.
Captions.ai vs Descript
Descript is a desktop-first, script-based video editor with excellent transcription accuracy and a unique overdub voice cloning feature. It is a powerful tool for podcast editors and talking-head interview producers, but it is not designed for mobile and its workflow is significantly more complex than Captions.ai's. If you produce long-form content on a desktop and need text-based editing, Descript is excellent. If you shoot on your phone and publish short-form content, Captions.ai is the better fit. The two tools serve largely different use cases and different creator profiles.
Captions.ai vs Adobe Premiere AI (Premiere Pro)
Adobe Premiere Pro with its AI-powered Speech to Text and Auto Reframe features offers professional-grade results, but the learning curve, subscription cost ($54.99/mo as part of Creative Cloud), and desktop-only requirement place it firmly in a different category. Captions.ai delivers comparable caption quality and superior mobile convenience at a fraction of the cost. Premiere Pro is for professional video editors; Captions.ai is for content creators who want results in minutes without post-production expertise.
Captions.ai vs Opus Clip
Opus Clip specializes in repurposing long-form video content — YouTube videos, webinars, interviews — into short viral clips automatically. It uses AI to identify the most engaging moments and adds captions and branding. Captions.ai, by contrast, is designed for videos you record yourself, not repurposed content. The two tools are complementary rather than competing: if you produce long-form content, Opus Clip helps you repurpose it; if you create original short-form content, Captions.ai helps you polish it. Creators with both needs can benefit from using both.
Final Verdict
Our Recommendation
Captions.ai is the best AI video tool available for social media creators who publish on TikTok, Instagram Reels, and YouTube Shorts. The eye contact correction feature alone is worth the subscription for anyone who shoots talking-head content regularly — it genuinely transforms the perceived quality of mobile videos by creating the intimate, direct connection with the viewer that defines viral content. Combined with industry-leading auto-captions in 28 languages, an integrated teleprompter, filler word removal, and AI dubbing, Captions.ai covers every major friction point in the short-form creator workflow. The mobile-only limitation is a real constraint for creators who prefer desktop workflows, and it is not the right tool for text-to-video generation or cinematic production. But within its target use case — mobile creator polishing a talking-head video for social media — it is unmatched. The Pro plan at $19.99/month is an easy recommendation for any creator publishing video content more than twice a week.
