👋 Hey Product Hunters!

I love watching foreign dramas and anime, but I was constantly frustrated by how hard it is to find good subtitles. Most AI subtitle tools expect you to upload huge video files to the cloud—not ideal for privacy or convenience.

So I built Submarine Player: a Mac video player that generates subtitles instantly as you watch—completely offline.

🎯 Who it’s for:

🌏 Fans of foreign dramas, movies, or anime with missing subtitles
📝 Language learners (toggle original + translated subtitles with ease)
🎥 Anyone who wants subtitles for videos—even in their own language
💾 People who want to export subtitle files (SRT, VTT, CSV) for later use

✨ Features:

⚡ Real-time subtitle generation while watching
🔒 Privacy-first: works fully offline (no internet required)
🎞 Supports all common video formats (MP4, MKV, MOV, etc.)
🌐 19 languages supported
📁 Batch Processing — queue up multiple videos and export subtitle files (SRT, VTT, CSV)
🚀 Optimized for Apple Silicon

💸 Unlike most tools, Submarine Player also offers a one-time purchase option—no subscription required.

There’s also a free tier (7 subtitle generations/week), perfect for casual use.
