About SUBCAM

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), 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. FREE - 1080p 30fps recording (with a small #SUBCAM watermark) - All caption features: speech captions, AI captions, translation - All looks, caption styling, and fonts SUBCAM PRO (one-time purchase) - 4K and 60fps recording - HDR video - Exposure adjustment - Removes the #SUBCAM watermark Perfect for vlogs, street snaps, interviews, travel videos, language learning, and accessibility — shoot once, share immediately, captions included.
