Boyake is a Chrome add-on developed by andrewkfiedler. This free program falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. Boyake's main purpose is to blur out the English context sentences on Wanikani until they are hovered over.

With Boyake, users can now review their Wanikani exercises without being influenced by the English context sentences. This add-on blurs out the English sentences during the review process, allowing users to focus solely on the Japanese content. When users hover over the blurred sentences, the English translation will be revealed, providing additional context if needed.

It's important to note that Boyake only affects the review section of Wanikani and does not impact any other parts of the website. The add-on is designed to enhance the learning experience for individuals who prefer to rely solely on their Japanese skills during exercises. While the program is free, the developer is open to feedback to improve its functionality.
