Submerge: Convert Familiar Content into Your Target Language for Natural Exposure
Not for reading foreign text faster, but for turning the content you already understand into your target language—maximizing your natural exposure and comprehensible input.

About Submerge
The most effective way to acquire a new language is through "comprehensible input" — exposing yourself to the target language within a context you already fully understand. While most translation extensions are designed to help you quickly read foreign websites, Submerge does the exact opposite: it is built to create a seamless foreign language environment.

Submerge converts webpages and videos you are already familiar with (or currently reading in your native language) into your target foreign language. Because you already grasp the core message and background, you do not have to struggle to guess the meaning. Instead, you naturally map your existing understanding to the new foreign expressions, effortlessly multiplying your effective daily language exposure.

Core Features
Convert Familiar Text into Target Language As you read native webpages you already comprehend, Submerge converts the sentences into your target foreign language. Since you already understand the context, this allows you to absorb natural foreign expressions with zero cognitive pressure.
Sentence-by-Sentence Audio Synthesis Transform webpage content into your target language with sentence-by-sentence or continuous audio reading. Follow along with the content you already know while listening to native pronunciation, training your ear in a familiar context.

Foreign Dubbing & Bilingual Subtitles for Videos Provide target-language audio and bilingual subtitles for web videos. This turns the videos you already enjoy and understand into rich listening materials, making auditory practice highly accessible and easy to comprehend.

Save Personalized Contextual Expressions Instantly save converted sentences or vocabulary to your personal library along with their original context, allowing you to review real-world expressions encountered during your daily routine.
