✅How to Mark YouTube Videos as Watched (And See What's Still Unseen)

Why YouTube does not let you mark videos as watched

YouTube does technically track what you have watched — that is what powers your watch history and the red progress bar on thumbnails. But the platform does not give you a manual way to flag a video as 'I have seen this' without playing it, and there is no built-in visual cue for 'I have decided I am done with this video'.

YouTube has not stated a reason. Whatever the cause, the practical result is a feed where seen and unseen videos look identical at a glance.

What you can do natively

• Pause your watch history. Stops the algorithm from learning, but does not help with feed clutter.
• Use the red progress bar as a 'partially watched' signal.
• Right-click 'Don't recommend channel' on the Home tab. Affects recommendations, not the Subscriptions feed.

None of these solve the core problem: a manual 'I am done with this video' button.

Adding a Mark as Watched button

FolderTube adds a Mark as Watched control to video thumbnails in the YouTube subscription feed. Click it and the thumbnail is visibly flagged — typically grayed out with a checkmark — so you can tell at a glance which videos you have already watched or decided to skip.

The free plan includes a limited number of marks per month — enough to try the feature. Premium (starting at $2.99/month, with yearly and lifetime options) lifts the limit entirely.

How to use it well

1. Open YouTube and let your subscriptions load.
2. After watching a video — or when you decide to skip one — click Mark as Watched on its thumbnail.
3. The thumbnail is now visually marked, so on your next visit you can ignore it and focus only on thumbnails that are still 'unread'.

After a week or two of regular use, your subscription feed becomes a clearly two-state list: marked thumbnails are handled, unmarked thumbnails are what is left to deal with.

Common workflows

Inbox-style YouTube

Treat the feed like email. Watch what you want, mark the rest as watched, then ignore anything visibly marked on your next visit. Pairs well with topic-based folders so each folder feels like its own inbox.

Background-only filtering

If you watch certain channels purely as background while doing other things, mark them as watched after a single play so the thumbnails stop competing for attention with content you actually want to focus on.
