Watch Later Librarian Sync

Sorts your own YouTube Watch Later into a tidy library with AI. One click sync; new saves are filed automatically.

Your YouTube Watch Later is where good videos go to die. You save something meaning to watch it later, and later never comes. Hundreds of videos pile up until the list is too big to even open. Watch Later Librarian fixes that. Connect your account and it reads your Watch Later, then sorts every video onto five clear shelves so you can actually deal with the pile: Worth learning from Worth watching Music Just for fun Outdated It uses AI to judge each video from its title, channel, and length, and it tells you why it filed each one where it did. The more you correct it, the more it learns your taste. And it does more than sort. Open any video and get a quick TL;DR pulled from its captions, so you can grab the point without sitting through a whole hour. Press sync once and your entire library gets organized. After that it keeps itself up to date on its own, so the videos you save are already sorted the next time you open your board. What it touches, and what it does not: the extension reads your Watch Later only from your own signed in browser, and only when you sync. It sends your video titles and captions to your own private account and nowhere else. It never downloads or re-hosts videos, never reads other sites, and never sees your password. You watch everything on YouTube itself. Everything is free right now while we are in beta.
