I write notes that are very explorative and rambling on some topics. Like I have probably 100+ pages of notes on programming language design where I use my notes as more of a working memory than a cohesive document. In other cases I'll do competitive market analysis by looking at most products in a category and scrawling down first impressions, strengths, and weaknesses.

In some cases yes I'll synthesize that myself into something more coherent. In other cases an LLM can offer a summary of certain themes I'm coming back to, or offer a pseudo-outsider's take on what the core themes being explored are.

If something is important to me I'll spend the time to understand it well enough to frame my own coherent argument, but if I'm doing extremely explorative thinking I'm OK with having a rapid process with an LLM in the loop.
