nGeneChromeTools

Manage bookmarks, copy YouTube transcripts, download page images, and restore right-click when enabled.

nGeneChromeTools helps users collect, organize, and reuse useful information from webpages in one browser workspace. Key features: * Manage, search, create, rename, move, and delete Chrome bookmarks. * Copy the complete available transcript from the active YouTube video. * Include or omit transcript timestamps. * Add the video title and current URL to copied transcript output. * Download page images by selected format and minimum file size. * Add an optional filename prefix to downloaded images. * Restore right-click, text selection, and copying on webpages that attempt to block those actions. * Review, copy, and clear a sanitized local diagnostic log. * Operate without advertising, analytics, subscriptions, or external AI services. Bookmark actions are performed only when requested by the user through the extension interface. Transcript preparation runs only on a supported YouTube video. Necessary transcript requests are made only to validated Google or YouTube endpoints. Page-image scanning and downloading begin only after the user selects the download feature. Images are saved through Chrome to the user's download folder. Right-click restoration is optional and disabled by default. When enabled, it restores native context-menu access, text selection, and copying on regular HTTP and HTTPS webpages. The saved setting persists locally until it is changed. nGeneChromeTools does not sell or transmit page content, selected text, bookmarks, keystrokes, mouse activity, clipboard contents, browsing history, transcript text, or diagnostic logs to nGene Hemodynamic Research Center. Extension settings and sanitized diagnostics remain in Chrome local extension storage. © 2026 Hyunsuk Frank Roh, MD. nGene Hemodynamic Research Center.
