Provides a quick and convenient way to bookmark web pages directly from the browser to the user's Hatena Bookmark account, without navigating to the Hatena website separately

User browses a web page → clicks extension popup (or uses Ctrl+B) → popup loads bookmark/comment forms via iframes from b.hatena.ne.jp → user adds optional comment and tags → submits bookmark via bookmark.hatenaapis.com API → page is saved to their Hatena Bookmark account. Content script also checks if the current page is already bookmarked and updates the extension icon accordingly.

Target users: Hatena Bookmark users in Japan / Japanese-language web readers who use social bookmarking / Users who want to save and organize web articles

Source code is heavily minified/webpack-bundled, making it difficult to read exact logic for authentication and API calls
Cannot fully verify whether the extension shows a login screen or silently fails without a Hatena session
Cannot confirm whether Hatena Bookmark Gold/premium features are referenced in the minified code

Monetization

No paid features detected

No evidence of paid features, premium tiers, subscription gates, billing APIs, or upgrade UI within the extension source code. The keyword hits for 'pro' and 'license' are from Apache License 2.0 boilerplate text in the minified bundles, not related to paid product tiers. All features listed in the store description (bookmarking, comments, tags, read later, private bookmarks) are standard Hatena Bookmark features. Hatena Bookmark does have a separate premium service (Hatena Bookmark Gold), but the extension itself does not gate any features behind payment.

Reason: The extension's core workflow is bookmarking web pages to a user's personal Hatena Bookmark account via the bookmark.hatenaapis.com API and b.hatena.ne.jp. The popup includes a profile link to https://b.hatena.ne.jp/my and a profile icon area (.tab-account). The extension relies on the user being logged into the Hatena Bookmark service in the browser (cookie-based authentication found in minified source). Without a Hatena account and login session, the bookmarking workflow cannot complete. The extension itself has no built-in login UI—it delegates authentication to the destination service.
