I frequently read documentation, papers, and product updates from overseas AI model teams such as OpenAI, Anthropic, and Google DeepMind, and Immersive Translate has almost become my default reading environment. What impresses me most is that it does not disrupt the original page context or reading rhythm: the source text remains, and the translation is smooth enough to use. For people who often track foreign AI tools and model updates, this kind of experience is not just nice to have; it saves real time.
