YouTube to chart: see where a video spends its time
Numbers said aloud are easy to miss and hard to compare. A chart puts them side by side.
BlogPen draws charts from the note. The simplest is minutes per section, which shows at a glance where a talk spends its time; from the note you can also ask for a chart of the figures the speaker gives, each tied to the words it came from.
A real example
NASA Science · ScienceCasts: The Mystery of High-Energy Cosmic Rays · 3:39 · Public domain: US government work (NASA)
TL;DR from the note
- Most cosmic rays are thought to come from supernovae, but the origin and acceleration of the most energetic particles remain a major mystery.0:39
- CREAM measures cosmic rays above most of Earth's atmosphere, recording their energy, direction, and particle type.2:05
- Moving CREAM to the space station enables longer monitoring without atmospheric interference, helping it measure higher-energy cosmic rays.3:10

- Clean labels in your palette, light or dark
- The same chart in the Excel and PPT outputs
How it works
- Create a note from the YouTube link.
- Open the Chart tab to see the minutes per section.
- Ask for a chart of the figures you care about and check each bar against its time.
Good to know
What if the video has no numbers?
Every note still has a time chart: how many minutes each section takes. A figure chart is only drawn when the speaker gives figures.
Can a chart value be made up?
A value must come with the transcript words that say it. A bar without a source is not drawn.
Can I export the chart?
It travels with the note into Excel, as a native chart, and into PPT, as a slide.
