SUBCAM

Speak, and your words appear on the video in real time. Now with on-device translation, AI scene captions, and a fully redesigned capture screen.

SUBCAM is a camera that burns live captions right into your video as you shoot.

Speak while recording and your words appear on screen in real time — and they are baked into the saved video. No editing, no exporting to another app.

KEY FEATURES

• Live Speech Captions On-device speech recognition turns your voice into subtitles the moment you speak — captions appear live even before you start recording. Supports Japanese, English, Chinese, Korean, and more.

• On-Device Translation (iOS 18 or later) Speak in one language, caption in another. Real-time translation runs entirely on device, no internet connection required. Switch it on with one tap from the capture screen.

• AI Scene Captions Point the camera at anything and AI describes what it sees, as short words or full sentences. Bring your own API key for Claude, ChatGPT, or Gemini, connect a local LLM, or use Apple Intelligence fully on device. You can even choose the exact model for each provider.

• Cinematic Looks Switch between Standard, CinemaScope (2.39:1 letterbox), Cinematic tone, and Monochrome with one tap, right above the shutter. Letterbox color is customizable.

• Style Captions While You Shoot Tap the "Aa" button to change caption size, position (top / center / bottom / danmaku barrage), and font — with a live preview behind the panel. Five fonts including Japanese Gothic and Mincho.

• A Camera That Feels Familiar Standard camera layout: big shutter, recent-clip thumbnail, 0.5x/1x lens switch, pinch zoom, tap to focus. Non-essential controls fade away while recording so you can focus on the shot.
