Illa Helper is a browser extension that utilizes the theory of 'understandable input' to provide an immersive reading experience for language learners. It replaces certain words on web pages with vocabulary from the learner's target language, thereby enhancing their vocabulary and linguistic skills.

The extension comes with a comprehensive audio learning ecosystem and intelligent multilingual translation features, including automatic language detection, phonetic display, AI-based word explanation, dual Text-to-Speech (TTS) synthesis, and interactive pop-up boxes.

With Illa Helper, users can download the extension from the GitHub repository and access a range of language learning resources, including a community forum, a Telegram channel, and a group chat. The extension is compatible with popular browsers such as Chrome, Edge, and Firefox.
