Sometimes when working through difficult problems I will write pages of notes exploring a topic from a bunch of different angles until my brain is a bit exhausted.
I've found LLMs work reasonably well to just copy-paste that blob of thoughts into to have them summarize the key points back to me in a more coherent form.
I find value in going from the unstructured blob of notes into structured and coherent thoughts myself, rather than with an LLM.
If I understand something well, I can write something coherent easily.
What you describe feels to me along the lines of studying for an exam by photocopying a textbook over and over.
