I was looking for something like this. As I have been reading an consuming information from multiple and that seems to be going down the rabbit hole. Recall seems to be a perfect service with summary and creating flashcards for spaced repetition to help us to utilize the content we read.
I loved how accurately the Chrome extension worked! It helped me summarize PDFs for my research work and generate quick insights. What I loved most was the knowledge base that automatically categorizes and connects the saved summaries.
Congrats on the lunch. Useful tool and was wondering if you set the Spaced Repetition functionality only for specific category/content of your knowledge tree
