DeepSRT Mobile

Watch YouTube with AI superpowers: live bilingual captions, instant summaries, and full transcripts — in your language. DeepSRT Mobile plays any public YouTube video through the official player and adds powerful tools for understanding it: LIVE CAPTIONS, TRANSLATED Native caption tracks are translated on the fly into your language and rendered as elegant live captions over the video. Drag to reposition, slide the right edge to resize, and choose your own background color, opacity, and corner roundness. AI SUMMARIES AND TRANSCRIPTS Every video gets a structured summary and a tap-to-seek transcript, generated in the language you choose — nine to choose from. Tap any transcript line to jump right there. NO CAPTIONS? STILL FINE (PREVIEW) Videos with no caption track at all can be transcribed by AI (opt-in, using your own Gemini API key). Timing is paragraph-grade in this preview — summaries and transcripts are the focus. BUILT FOR IPHONE AND IPAD Paste a link, search by keywords, or share from YouTube. On iPhone, rotate for a stable fullscreen experience. On iPad, use landscape split view to keep the video, summary, and transcript side by side with a draggable divider. YOUR KEYS, YOUR CONTROL Bring your own API keys (Google Gemini, or OpenAI-compatible providers). Keys live in the iOS Keychain and never leave your device. No account, no tracking, and no servers of ours in the middle. One-time purchase. No subscription. Launching at an early-bird price for a limited time — the price goes up after launch.
