Thank you very much for bringing this to Appsumo.

Have one suggestion

I already have some of the book summery video saved as playlist from youtube. Most of them are animated with pictures so are good to watch and remember.

Do not see animated videos here, most of them are with texts and may be 10% of the video with some pics. Listening with pictures/visualization increases chances of remembering it for longtime. So if you can make animated then it will be great.
