【文賢】文章の校閲・推敲支援ツール is a Chrome extension developed by bunken-extension. It is a free add-on tool in the Browsers category. This extension serves as an aid for proofreading and editing web page content.

With this tool, users can select any text on a web page and right-click to access the "Send to 【文賢】" option in the context menu. The selected text will then be checked using the 【文賢】 service.

In case the context menu is not available, users can still select the text and click on the 【文賢】 icon located in the browser's toolbar.

Please note that the 【文賢】 service requires a separate subscription and users must be logged in to access its features.
