Questions

Is TED-Ed worth watching?

Across the 21 videos we measured, the median Gistil Score is 67 out of 100, and 11 came out worth watching outright. The score measures how much of the runtime carries substance; it is our own measurement, not a YouTube metric.

What are the best TED-Ed videos?

The three densest ones we have measured are listed above, each with the minute its value starts — so you can open one at the second it begins to pay off.

How honest are the titles on TED-Ed?

Median title honesty across those videos is 90 out of 100 — how closely a title matches what the video actually delivers.

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.
