Combine Courses, Series, or Research Lists

FAQ

How many playlists can I paste?

The UI accepts multiple lines. Very large batches may be limited by service capacity or request time, so smaller batches are easier to review.

Does this work with private playlists?

The calculator can only read public playlists. Private playlists and removed videos may appear as unavailable or return a clear error.

Is my YouTube API key exposed?

No. You only paste a public YouTube link. The tool does not ask for your YouTube or Google sign-in, and no personal account credentials are shown in the browser.

Can I calculate only part of a playlist?

Yes. Use the start and end video range controls to calculate only the videos you plan to watch.
