"AI as Retrieval, Not Generation: Why I Stopped Letting AI Into My Vault (And the Plugin That Came Out of It)"

Six months into using AI heavily with my notes, I caught myself staring at an Obsidian entry I couldn't remember writing. Not in the "wow, I forgot I wrote that" sense. In the practical sense: I genuinely couldn't tell whether the paragraph in front of me was a thought I'd had, or an AI summary I'd accepted, or a paraphrase I'd nodded along with somewhere between the two. The skill was intact. I could still write, still think, still synthesize. What had quietly dissolved was the boundary between what I think and what I read and accepted.
