Inkah is a subscription-based browser extension for Firefox tailored for language learners focusing on Korean and Mandarin Chinese. This tool integrates with Netflix, allowing users to hover over subtitles for immediate translations and definitions. It accommodates both Simplified and Traditional Chinese as well as Korean, providing features like verb conjugations and Romanization. Additionally, the extension includes a customizable pop-up dictionary that offers definitions, audio playback, and bookmarking for effective vocabulary tracking.

Beyond Netflix, Inkah supports Google Docs and includes adjustable settings for font size and dictionary display options. The text-to-speech functionality allows users to listen to words and sentences, aiding in pronunciation mastery. While there are some navigation limitations with subtitles due to Firefox API constraints, Inkah remains a comprehensive learning tool, featuring an intuitive interface and advanced settings for a personalized learning experience.
