NeonLingo is a word translation tool designed to assist users in learning unfamiliar languages while browsing web pages. It allows users to mark translated words and automatically recognizes if these words still exist on the websites subsequently visited. By offering repeated prompts and simple operation commands, it simulates the experience of tagging English words on web pages, facilitating language learning in an easy, intuitive manner. The tool also includes a unique automatic vocabulary highlighting feature, which remembers every word the user has translated.

The tool equally incorporates AI-driven precision in understanding and translating vocabulary in context, leading to more accurate translations. Furthermore, NeonLingo offers multiple convenient interactive modes, enabling users to manage their highlighted words effectively, thereby ensuring a smooth and uninterrupted reading experience. Thus, it is positioned as an innovative solution for language learning, seamlessly integrating language translation, user-friendly reading, and memory enhancement.
