About Subtitles
Subtitles (Auto CC) is an iOS app that uses AI to automatically generate captions for videos from your gallery or recorded live. Simply upload or record a video, and the AI recognizes speech and produces subtitles in seconds. You can then customize text style from normal to 3D, adjust position and size, add stickers and logos, remove backgrounds, and add music. It's designed for content creators who need fast, accurate captions without manual effort. The app is free with no ads or watermarks, making it a standout choice for beginners and pros alike. Built-in translation lets you output subtitles in any language, and social network templates provide a live preview as you work.
Behind the Verdict
Subtitles (Auto CC) is a pure mobile play for captioning. It does one thing — turn speech into styled subtitles — and does it for free with no ads or watermarks. That's rare. For content creators cranking out TikTok, Reels, or Shorts, this simplifies a tedious step. The AI accuracy is solid, and customization options (3D text, background removal, translation) add real value. Where it bites: iOS only, no desktop editor, no batch processing, no API. If you edit on a computer or need captions for long-form YouTube, you'll look elsewhere — CapCut (free) or Descript (paid) offer more. But for quick mobile captions on a budget, this is a reliable pick. In practice, we'd reach for this when we need a subtitle overlay in under a minute without opening a laptop. The lack of a web presence limits collaboration, but for solo creators, it's hard to beat the price.
