Pinbook is a lightweight Chrome extension developed by millilux that allows users to easily add bookmarks to Pinboard. With just a single click or keyboard command, users can add the current tab to their Pinboard, similar to Chrome's default bookmarking system.

The extension features a minimalist UI, making it intuitive and user-friendly. To bookmark a site, simply visit the desired webpage and click on the pin icon or use the shortcut Cmd/Ctrl+i. Users can then edit the title, description, tags, and choose whether the bookmark should be private or marked for reading later. Autocomplete functionality for tags is also available, making the process even more efficient.

Pinbook also offers customization options, allowing users to set default privacy and read later settings for new bookmarks. Additionally, users can choose to show or hide the private and read later checkboxes. Keyboard shortcuts can be configured through the chrome://extensions page.

Overall, Pinbook provides a seamless and convenient way to add bookmarks to Pinboard, enhancing users' browsing experience.
