>Instead of relying on vector databases or artificial chunking, it builds a hierarchical tree structure from documents and uses reasoning-based tree search to locate the most relevant sections.

So are we are creating create for each document on the fly ? even if its a batch process then dont you think we are pointing back to something which is graph (approximation vs latency sort of framework)

Looks like you are talking more in line of LLM driven outcome where "semantic" part is replaced with LLM intelligence.

I tried similar approaches few months back but those often results in poor scalablity, predictiablity and quality.
