Auto Captions: AI Subtitles

Turn silent scrollers into engaged viewers — automatically.

85% of social media videos are watched WITHOUT sound. Videos with captions get 38% more engagement, 31% longer watch time, and a 12.5% conversion rate vs 6.9% without. If you're posting to TikTok, Instagram Reels, or YouTube Shorts without captions, you're leaving reach on the table.

Auto Captions is the AI subtitle generator built for social media creators. Record or import any video, and our AI transcribes every word with precise timing — then you pick your style and export.

🎨 DESIGN YOUR CAPTIONS
Choose from bold fonts including Montserrat, custom colors, and animated styles: word-by-word pop, bounce, fade, and highlight. Make captions that match your brand, not just white text on black.

📱 SMART SAFE ZONES — NEVER HIDDEN AGAIN
TikTok buttons. Instagram Reels UI. YouTube Shorts subscribe bar. Facebook. Snapchat. Each platform covers different parts of your screen. Auto Captions automatically positions your subtitles in the safe zone for every platform — your captions are always fully visible, guaranteed.

⚡ ONE EXPORT, EVERY PLATFORM
No juggling versions. Your captions sit in a safe zone that clears TikTok, Reels, Shorts, Facebook and Snapchat all at once — post the same video everywhere.

🔒 YOUR VIDEO STAYS ON YOUR PHONE
Unlike cloud editors, your video never leaves your device. Only the audio is sent for transcription (to our secure API), then everything is processed locally. Full privacy, no uploading 500MB files.

🌍 90+ LANGUAGES
English, Spanish, Portuguese, Hindi, Indonesian, Arabic, French, German, Japanese, Korean — and 90+ more. Word-by-word animated captions in any language.
