Privacy
Your study material stays yours.
Furigana Online is designed to work without an account and without storing the Japanese material you study.
Text and furigana
Japanese text and furigana processing run in your browser. The site does not save the text you enter.
Images and OCR
Image recognition runs in your browser. Images are not uploaded to or stored by Furigana Online.
Speech playback
Japanese speech uses voices provided by your browser or device. Voice availability and quality depend on that device.
Local preferences
The site may save interface language and reading-size preferences in your browser so the tool is easier to use next time.
