# JADOU

JADOU is an evolving, in‑context Japanese language toolbox created by a specialist in Japanese language and culture. You can look up readings and meanings, insert furigana, build glossaries, and automatically select sentences with it. Everything runs locally with no network access.

## Notable Features

- Support for looking up inflected word forms
- Mobile support
- PDF support
- Lineage (https://github.com/ycnmhd/obsidian-lineage) plugin support
- One-click/hotkey-binded sentence selection

## How to Use

- Select a Japanese expression _containing kanji_ and trigger the lookup command to open the dictionary panel. You can use the ribbon icon, the command panel, a keyboard shortcut, or the editor’s context menu to do this.
- The “common,” “rare,” “irregular,” and “outdated” tags next to the entries refer to the kana usage / readings. These guide you toward the most context-appropriate bundle.
- Select an entry and press <kb>Enter</kb>, or click it, to add it to your glossary.
- Drag around entries inside the glossary to reorder them.
- Drop an entry into the editor to copy it.
- Use the Sort button to reorder entries in Japanese alphabetical order.
- Right‑click an entry to remove it from the glossary.
- Press <kb>Space</kb> or right‑click an entry in the dictionary panel to insert furigana instead of adding it to the glossary.

## Roadmap

Feature requests, bug reports, and pull requests are welcome.

## Security

- This plugin has zero dependencies.
- JADOU requires an internet connection only to download or update its dictionary data. It operates entirely offline otherwise and does not transmit or store your personal information.
