## Description

Nazeka is an advanced Japanese dictionary Chrome extension designed as a replacement for Rikai. It features very fast text scrubbing and a built-in clipboard grabber to enhance Japanese language learning efficiency. Users can easily look up words by simply hovering their mouse, similar to other popular tools like Rikaichan and Yomichan.

Beyond basic dictionary functionalities, Nazeka supports "mining," which enables automated flashcard creation compatible with Anki through Ankiconnect integration. Its intuitive UI includes configurable hotkeys for features such as sticky mode, audio playback from jpod101 servers, and a mining interface. Though primarily developed for desktop, Nazeka offers experimental support for Android on Firefox Nightly. This extension is a powerful tool ideal for learners aiming to deepen their Japanese vocabulary and comprehension.

## Review summary

Nazeka is a highly praised Firefox add-on for instant word lookup, especially favored on Android and Windows. It outperforms similar tools like Rikaichan with features like EPWING dictionary support and audio. Users appreciate its speed, convenience, and clean design. However, multiple users report issues with popup positioning and functionality, requesting improvements such as better popup placement controls, word highlighting, and improved popup hide behavior.

### Pros

- Works flawlessly on Firefox Android and Windows, supporting touchscreen use effectively.
- Faster and more powerful than similar add-ons like Rikaichan and Rikaichamp, with additional features such as EPWING dictionary support, audio, and frequency list information.
- Highly convenient for instant word lookup, even on phones, making it a go-to tool for language learners.
- Clean, curated interface and a dynamic set of integrated platforms and services.
- Promises to replace the late Rikai-sama in functionality and power.

### Cons

- Popup positioning issues, especially on Android, where the popup sometimes overlaps the selected word.
- Lack of a feature to manually change popup positioning or set popup location (top/bottom of screen).
- No option to highlight the selected word upon lookup.
- Popup disappearing behavior could be improved, such as closing when tapping outside the popup or on the popup itself.
