The Japanese Helper for Obsidian plugin simplifies the process of converting romaji into Japanese scripts directly within your notes. With just a shortcut or command palette entry, selected Latin text can be transformed into either hiragana or katakana. It smartly handles nuances like small kana, long vowels, particles, and double consonants, making it more accurate for everyday usage. The plugin is lightweight and works seamlessly in the editor, supporting custom hotkeys for quick access and optional notifications after conversion.
