ChannelLens by Fahad

ChannelLens helps you keep private context about YouTube channels you encounter. Save a label and optional note for a channel, then ChannelLens shows a reminder when you later visit that channel or watch one of its videos.

Choose from built-in labels such as Biased, Misinformation, Clickbait, Unreliable, and Useful, or create your own labels. Your reminders are deliberately limited to relevant channel and video pages, avoiding alerts on the YouTube homepage, search results, feeds, playlists, and unrelated recommendations.

Use the management page to search, edit, or delete saved channel reminders. You can also export your data as JSON for backup or import it when moving browsers. ChannelLens supports system, light, and dark themes.

All labels, notes, and channel metadata stay in your browser’s local extension storage. ChannelLens uses no analytics, remote scripts, or external network service, and it never uploads your data.
