- Go to the online version of the “Japanese Sentence Analyzer”
- Go to the “Japanese Sentence Analyzer” GitHub project.
“Japanese Sentence Parser” is an open-source tool. For those who don’t want to use the online version, it can be deployed locally, but you’ll need to enter your own Gemini API key. With a generous free daily quota, it’s essentially completely free to use.
There are mainly 5 major features:
- Smart Grammar Annotation: One-Click Output of Parts of Speech, Kana, Romanization, and Grammar
