Show HN: LongTerMemory Study tool with no subscription built with QDrant and RAG

https://longtermemory.com
1•aledevv•4h ago
After trying out various study tools, I decided to create my own.

I wanted a quick and simple way to upload any study material, have the app generate questions, and then set up a daily review schedule.

So, I built it by creating a RAG system and a scheduler to trigger the daily review sessions.

Nice use of Qdrant for the retrieval layer.Curious how you're handling the question generation, are you chunking the study material and generating per chunk, or doing something more document-level?
