Yomitan provides powerful features not available in other browser-based dictionaries:
💬 Interactive popup window for displaying dictionary definitions.

💲 Completely free and open-source.
🛡️ Privacy-conscious: we transmit only the minimum amount required of data outside of the extension by default (i.e., we only transmit the single word you are looking up if and only if you click the audio playback button on it). All data transmission is configurable. More information is available in our privacy policy.
