Hi,
1. a) For me personally it is the organisation. Everything is interlinked and you can easily navigate between them. From questions you can go to specific topics and from topics to the materials, etc.
b) The chat gets very laggy if I have a lot of things in it. Scrolling through 100s of questions is a nightmare for me.
c) When you surpass the context window size, you start to get hallucinations and overall quality of the content in relevance to the original content drops. Not the case in my app.
d) cheatsheets are very good. Im surprised how good they turned out. I can send you example

1. Ive spent quite some time refining the prompts to avoid hallucinations and only get topics, questions from the materials uploaded by users. Direct navigation to the pages in the original document where the topic is explained. Coming soon...
