Show HN: TubePen – My attempt to get more out of YouTube learning

Hi HN! I made this because I always forget what I'm trying to learn from YouTube.

Test yourself: Can you remember the main concepts from the last (educational) video you watched?

So, why not highlight and take notes on YouTube videos, just like in books? That's TubePen.

Sign in, replace "youtube" with "tubepen" in your YouTube URL, and you're ready to retain more from your videos.

I’d love your feedback! What do you think of my landing page? Use the 10-day free trial and see if it’s useful for you.
