JGloss is an application for adding reading and translation annotations to words in a Japanese text document. This can be done automatically and manually. When a text document is first opened, kanji words will be looked up in a dictionary and the first reading and translation (if any) used to annotate the word. The user can then edit the annotations: choose among the readings and translations found in the dictionaries, enter your own readings and translations, remove annotations, and add new annotations. The document can be exported as plain text with annotations, HTML, or LaTeX.
