Hi everyone! 👋 We’re thrilled to introduce Loomur today! Adding engaging subtitles to short-form videos (Reels, Shorts, TikToks) is essential since so many people watch on mute. However, relying on cloud-based tools can be slow, tedious, and often raises privacy concerns. That’s why we built Loomur—to bring fast, stylish, and 100% private AI subtitling directly to your iPhone. Here is what makes Loomur special: 🔒 Local AI Transcription: Your video and audio never leave your device. No server uploads, total privacy. 🎨 Full Customization: Edit text, change subtitle styles, and adjust placement easily. ✨ Keyword Highlighting: Make your core message pop by emphasizing key words with different colors. 📱 Vertical-Ready: Perfectly designed for short-form social content. We built this for creators who want a simple, secure, and flexible workflow. We’ll be here all day answering questions. We’d love to hear your thoughts, feedback, or any feature requests you might have! Let us know what you think! 👇

The on-device transcription feels pretty quick and it is nice knowing nothing gets uploaded. Highlighted keywords actually make the captions pop more than I expected.

On-device transcription is a great call for privacy. One thing that would make this even better for me is letting me save my own caption style presets so I can quickly switch between looks for different accounts without redoing the customization every time.

Love the on-device privacy angle, that is a real differentiator. One thing I would love to see is a batch export option so I can style subtitles for a whole series of clips at once instead of doing each one by hand.
