The one place I won't let AI in
A small confession from inside my Obsidian vault, and something I didn't expect to find.
Hey friend,
Quick confession before your week starts.
I have Claude open right now. I used three different AI tools yesterday (not seriously, just checking Gemini on my pixel). I’ll probably use one before I finish writing this letter to you.
But there’s one place in my workflow where I’ve quietly drawn a line — my Obsidian vault. No co-pilot. No autocomplete. No “improve this paragraph.” Just me, the cursor, and whatever half-thought I caught on the way to the kitchen.
It wasn’t a principled decision. I didn’t sit down one day and decide to protect my thinking from the machines. It happened slowly, the way most real changes do.
For about a year, I’d been letting AI sit closer and closer to my writing. Drafting with suggestions on. Asking for “tightening” before I’d finished the thought. Pasting half-formed ideas into chat windows for feedback. It felt productive. Every session ended cleaner than it started.
But I’d open my notes a week later and not quite recognize the thinking inside them. The sentences were mine. The shape wasn’t.
That’s the part that took me a while to name.
When I finally settled on Obsidian — after the embarrassingly long tour of sixty-plus apps — one thing started doing quiet work in the background. There’s nothing in there waiting to finish my sentence. Nothing nudging me toward the average phrasing. The vault is just… quiet.
And three things came back that I hadn’t realized I’d lost.
The weird half-formed thoughts I would have let a model “fix.” (Half my best essays started as a sentence I’d have edited out.)
The feeling of being stuck — and then unstuck. Not by clicking regenerate, but by sitting with the wrong question long enough to find the right one.
And, strangest of all, conversations with old versions of myself. Re-reading notes from February and noticing I disagree with what I believed in August. A model summarizing those notes for me would have flattened that. Re-reading them did something else.
I’m not writing this to tell you AI is bad for thinking. I use it constantly. I’m writing it because I think most of us haven’t asked ourselves the more useful question:
Where in your workflow are you supposed to be the one doing the thinking?
Mark that part. Keep AI out of just that part. Let it back in everywhere else.
For me, it’s the empty markdown file at 6 AM with my coffee. For you, it might be a paper notebook, a voice memo on a walk, the back of an envelope. The format doesn’t matter. The protected space does.
That turned out to be the thing I’d been missing.
See you next week,
Stay Productive, keep writing.

P.S. If you write back and tell me where your protected space is, I’ll read every reply. Genuinely curious.
