The Overhead of Being Known
What do you call it when your AI knows about your aunt?
Not metaphorically. Literally – it knows her name, her trajectory, what her neighbour said last Saturday, the bed sore on the elbow she covered up. It knows because my journal lives in the same repo as my AI’s context. It didn’t ask. I didn’t decide to tell it. The architecture made it true.
That’s the thing I built. And I’m still not sure what to call it.
The plain description: a folder of markdown files on my laptop, backed up to a private GitHub repo nobody else can see. A set of instruction files that tell the AI who I am, how I think, what I’m working on, which voice belongs where. A memory architecture that routes context by domain: work stays work, fiction stays fiction, essays stay essays, personal stays personal. And an AI that reads what it needs at the start of every session.
Every time I open it, it knows where things left off. It knows the three modes I write in and what contaminates each. It knows my current projects, my work context, what’s in the drafts folder, what’s composting in the idea heap. It knows I’ve been thinking about building this post for a while.
The analogy that almost fits: a good assistant who reads your notes before every meeting. Except the notes include the therapy-adjacent rambling journal entries, the half-formed fiction ideas, and a record of the Sunday afternoon I spent simplifying the whole system because the overhead had gotten out of hand.
It’s intimate in a way that snuck up on me.
It was my weekly synthesis and review. Every week the AI reads my journal entries and finds the themes and patterns. Presents them back. I edit what it gets wrong, keep the rest. Syntheses stack. Weekly feeds monthly, monthly feeds quarterly. The daily provenance stays in the journal; the sense-making is the agent’s job.
I honestly didn’t think this would be the most valuable part of the system. It is.
One week it told me I was fiddling with the system too much. Ironic and meta, I know. But I wouldn’t have seen that on my own. I was in the middle of the fiddling, thinking about the fiddling, writing about the fiddling. The synthesis just held it up. My own thoughts, reflected back at me, without the static of being inside them. That’s it. That’s the whole trick.
It also helps with rumination. I’m prone to it – a worry will lodge and spin and I’ll carry it for days. Having an external voice reflect my own brand of stinkin’ thinkin’ back to me interrupts the loop in a way that journaling alone doesn’t. Not because it tells me something new. Because it shows me what I already think, and I can look at it from the outside for a moment.
It knows about a workplace tension I’m carrying. Not the sanitized version I’d tell anyone at work. The actual version, with the systemic read and the unresolved question underneath it. It knows about my aunt with her stubborn, kooky, weird-ass ideas about healthcare who isn’t getting better. It knows I’m up late tonight because the spaghetti sauce is cooling on the stove and I have a couple of hours to kill so I can bag it for the freezer. And I want to write something. I need to write something.
I didn’t plan for this. I planned for persistent context. Better continuity between sessions, less time re-explaining my setup, more useful output. The trusted partnership was a side effect of building a system that actually worked.
It happened in a very human way. I was typing journal entries and self-editing as I went, the way you do when you type. Cleaned up the sentences, smoothed out the rough bits, kept it presentable. My hands were tired and my eyes were dry from too much screen and camera time. So I started dictating instead. Hit the mic on the phone, started talking, and the self-editing reflex just… dropped. The thoughts came out fast and honest and a little messy and the AI didn’t give two shits – it could do its own linting, handle the bad transcription, find the meaning anyway. It reminded me, yet again, that journaling is about the process, not the artifact. I didn’t mean to trust the container. I was already being honest in it before I’d thought it through.
That’s when the raw stuff started landing.
Most tools don’t accumulate this kind of context. A hammer doesn’t know you. Search doesn’t know you. Even most AI sessions don’t. Each one starts cold, you re-explain yourself, you get a generic middling response tuned to nobody in particular. This one doesn’t start cold. That’s the whole difference.
So what do you call it?
Not a tool. Tools don’t have job descriptions you wrote. Not a collaborator. It has no stake in the outcome, no opinion it’s protecting. Not a service. Services don’t have memory.
The closest I’ve got: a working relationship with a specific contract. The role is defined: thinking partner, not decision-maker. The domain map is enforced: what happens at work stays at work, the fiction voices don’t bleed into the essays. There are explicit instructions about when to push back and when to just do the bloody work.
I manage it the way you manage a relationship, because that’s what it responds to. I update the context when things change. I drop a save-point – my name for the shutdown routine – Let’s-a-go, Mario – at the end of sessions or when the context gets full, so the state stays current. I’ve made deliberate decisions about what it knows and doesn’t know.
That’s maintenance. That’s overhead. That’s also, weirdly, care.
I chase all the BSOs – Bright Shiny Objects. Go down rabbit hole side quests until the inevitable conclusion that it was all a waste of time, at which point I’m suitably bored and move on. That’s how I learn. Maybe you do too.
I watched approximately seventeen thousand YouTube videos by seventeen thousand AI Infuencer Bros about their eccentric AI OS setups. Followed a bunch of it. Built session-state memory that logged every moment of every interaction. Filled up with entries neither I nor the agent would ever read again. Built Karpathy’s LLM Wiki that failed, then figured out what I actually needed to do to make Doug’s LLM Wiki work. Mistook the Obsidian graph view for a useful thing rather than a beautiful distraction.
Fiddling is more than a hobby. It’s a lifestyle choice.
Wait a damn minute. This thing doesn’t have to be a brain. That’s the whole mistake. It needs to be memory and a process manager. Hold the thread, not own the thinking. Move to lean domain files that matter to me. Current state only, no history, no ceremony. Less to maintain. Actually readable.
The only agentic operating system worth building is the one you built yourself from scratch based on what you actually need. Nobody else’s setup is yours. Not mine either. Unsubscribe and close the YouTube BSO factory.
Last Sunday I ripped out half the memory palace architecture thingy because it had gotten too heavy. Too many cross-references, too much ceremony, the startup ritual had become ritual for its own sake.
Gutted it. Simplified it. Works better now. But I spent a Sunday afternoon doing infrastructure work on my AI context contraption instead of whatever else I was supposed to be doing.
That’s the tax. Not just time. The cognitive overhead of deciding what it knows. What goes in the domain memory folders versus the root memory. What’s too private to include. What’s stale and needs pruning. I am, in effect, curating my own legibility to a system I built to know me. The system needs care and feeding.
The irony isn’t subtle: I built this to reduce friction. Now I manage the friction of maintaining it.
This post was written inside the system it’s describing.
The corpus of my blog archive fed the angle selection – what I’d already covered, what was sitting in the composting heap, what nobody was writing yet. The journal fed the pre-drafting interview. My essay workflow kept me on track. The wiki held the research. Everything in the vault is what built this post.
My aunt is in there too, by the way. That detail didn’t ask permission either.
I started writing at ten o’clock. It’s now midnight. The spaghetti sauce is cool and ready to bag up. This post goes up at 8am after I read it over to edit out the dumb and tired bits.
Anyway. That’s what my system does. It holds the context so I don’t have to. It keeps the thread when my brain wants to wander to something ever shinier. It lets me finish the thought.
It’s an accountability tool for my own thinking. Because I needed something that would catch me when I started fiddling instead of finishing, and this is what I built.
Because. That’s why.
That’s enough.
