+When YouTube channel metadata is available, the Library tab groups videos by creator/channel. Use **All Titles**, **Anime**, or **YouTube** above the grid to filter the library. Channel pages show tracked videos and their stats without AniList controls. Existing channel entries are classified as YouTube automatically on startup, preserving viewing history and manual video assignments. Anime and YouTube entries with the same normalized title remain separate, including during stats sync. Channels are excluded from anime metadata matching, season repair, and duplicate recommendations.
 
 A library entry is identified by its parsed title plus any detected season, so the same show can end up on several cards when releases disagree about the title or omit the season tag. Two fixes are available:

+The stats Library groups tracked YouTube videos by channel when channel metadata is available. Select **YouTube** in the Library filter to see those channels separately from anime. Each channel page lists its videos, watch time, vocabulary, and mined cards. See [Immersion Tracking](/immersion-tracking#library).
