About this app
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 TAP MULTI-PLATFORM EXPORT
Select TikTok, Reels, Shorts, Facebook, and Snapchat — export all at once. One video becomes five platform-ready versions, each with correctly placed captions.
🔒 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.
🌍 99+ LANGUAGES
English, Spanish, Portuguese, Hindi, Indonesian, Arabic, French, German, Japanese, Korean — and 90+ more. Word-by-word animated captions in any language.
✏️ EDIT BEFORE YOU EXPORT
Mistranscribed a word? Tap to fix it in seconds. Adjust timing, split or merge caption blocks, change styles on the fly.
── HOW IT WORKS ──
1. Import video from your gallery or record directly
2. AI transcribes audio with word-level timestamps
3. Preview and edit captions
4. Choose your style (font, color, animation)
5. Select platforms (TikTok, Reels, Shorts, Facebook, Snapchat)
6. Export — one version per platform, ready to upload
── WHO IS THIS FOR? ──
• TikTok creators who want more views without re-editing
• Instagram Reels creators growing an audience
• YouTube Shorts creators maximizing watch time
• Anyone posting video content who knows captions = more reach
Stop losing viewers in the first 3 seconds. Add captions that keep people watching — automatically, in any language, on every platform.
