Despite being extremely motivated I found reading all the AGISF course material really hard. No offence Yudkowsky.
This led me to discover a platform called naturalreaders.com.
It takes content (e.g. PDFs, webpages) and simultaneously;
- reads it back to you
- highlights the content it is reading
I have provided a screenshot below to demonstrate.
It can do this for your emails, and I've even fed it books that didn't have audio versions!
Anyway, hope this helps.
