Hold one key to rewind and peek at subtitles in your native language on YouTube, Netflix, and Laftel. PeekSub makes learning a second language with video platforms effortless. Watch content in your target language (or with subtitles turned off). Whenever you miss a phrase, simply press and hold one key (default: V): 1. The video rewinds 5 seconds to the moment you lost track. 2. Subtitles switch to your native language with 0ms delay. 3. When you release the key, subtitles return to your default setting and playback continues smoothly. Key Features: • Supported Platforms: YouTube, Netflix, and Laftel. • 0ms Instant Subtitle Switch: Pre-fetches subtitle tracks so holding and releasing the key has zero network lag. • "None (Off)" Default Mode: Practice pure listening with subtitles hidden, and hold the key only when you want to peek at a line. • Smart Language Detection: Automatically highlights subtitle languages available on the current video and disables unsupported ones. • Fully Customizable: Choose your hold hotkey, default/hold languages, rewind duration (1–15s), and subtitle size (50%–250%).
