The Gistil Score is our own independent measurement of how much of a video's runtime carries substance. It is not a YouTube metric, not a public rating, and not the video's rating on YouTube. Gistil does not alter, download or cut any part of a video — the videos stay on YouTube and play there. Not affiliated with YouTube or Google.
