Open any article from a decade ago and click through the links in it. There is a good chance that some of them lead nowhere. Instead of the page you wanted, you get a 404 error, a parked domain advertising cheap insurance, or a redirect to someone else's site. This phenomenon is called link rot, and it is far more widespread than people tend to assume.

The web keeps falling apart. Pages go offline, accounts get deleted, papers slip behind paywalls, projects shut down. Usually a copy survives somewhere, in the Wayback Machine, archive.today, Common Crawl, scholarly indexes like Crossref, libraries like Open Library, and hundreds of smaller subject-specific archives. The catch is that they are all separate. To find out where something was saved, you used to open them one at a time: Wayback first, then archive.today, then a dozen academic and book databases.

When you find a deleted YouTube video through Tube Search, you typically get metadata: a title, description, upload date, and sometimes subtitles. That is already useful. But reading through raw subtitles to understand what a video was about takes time, especially for longer recordings.

We have added AI-powered video summaries to Tube Search. If a video has archived subtitles, the system can now generate a structured summary of its content in seconds.

Tube Search is a search engine for archived YouTube data. The service aggregates information from multiple public sources: the Wayback Machine (Internet Archive), Common Crawl, and various collected YouTube metadata datasets. When a video is deleted from YouTube, its page ceases to exist. But if a web archive managed to index that page before deletion, the video metadata is preserved: title, description, upload date, view count, thumbnails, subtitles.

Over time, external links in WordPress posts inevitably break, pages get deleted, domains expire, videos become unavailable. Checking hundreds or thousands of links manually is impractical. Archivarix Broken Links Recovery automates this process: the plugin scans your content, finds broken links, and replaces them with working copies from the Wayback Machine.
