An AI substrate, not an AI product

What's the thing you've been thinking about for years?

Because that is what your AI tools should be helping you with — and right now they can't, because they don't remember a single thing you've ever told them about it.

Your space is in here somewhere — or it isn't, and that's the point.

01
Tracking your daughter's eczema flares against what she ate that week.
02
Every parcel you've evaluated for that retreat center idea.
03
The arc of your kid learning to read, week by week.
04
Nine years of beekeeping notes you keep losing in different notebooks.
05
Your sourdough's behavior across seasons in this exact kitchen.
06
Trust decisions, three siblings deep, with the dates and the dollar context.
07
Climbing projects, attempts, beta, the move that finally clicked.
08
Aquaponics water chemistry, fish-by-fish, going back to last March.
09
Every song fragment you've hummed into your phone since 2019.
10
Your chronic-pain journal in a form a doctor will actually read.
11
A lesson plan that learns from what worked with last year's cohort.
12
The genealogy your aunt told you about that one Thanksgiving.

Every conversation you've had with an AI about your thing — remembered gone. Every nuance you taught it — re-derived, badly, next time. That's you, doing unpaid labor to keep your own context alive.

// The memory problem hiding inside every AI tool you use isn't a feature gap. It's a tax on the people whose work compounds.

If you care about a space, the AI you use should accumulate your perspective on it.

One database. Any AI plugs in. Your context lives in your brain, and the model — Claude, ChatGPT, a local Llama, whatever comes next — borrows it on the way to answering you.

The pattern is documented and shareable — see the working spec. The substrate is opinionated where it matters (capture grammar, sensitivity tiers, project-scoped domains) and boring everywhere else (Qdrant, FastAPI, MCP). Anyone can build one.

What we do at killercatfish is the next layer: spawning brains for specific spaces, on the right substrate for the job — cloud when speed matters, local when privacy does, edge when the brain needs to live where the work happens. We call that layer Nodal. This page is how you find out if your space wants one.

Tell us a space. We'll spawn a brain that holds it for thirty days.

Lives for 30 days, no card required
Yours alone — you'll get a private link
Keep it after thirty? Pick one of the three paths below.

Three ways to bring a brain home.

Tier 01 — Free

Do it yourself

The full pattern, written down. Paste a prompt into your own Claude Code (or Cursor, Cline, Aider — tool-agnostic) and it interviews you, then builds a brain on your machine in about thirty minutes. Yours forever.

Tier 02 — Hosted

We'll run it for you

You don't want to manage a database. We host the brain on our infrastructure, you get the dashboard and the MCP endpoint, your data is yours. Waitlist open.

Join the waitlist →
Tier 03 — Local

On your hardware

Your data never leaves home. We install the brain on a local model — Ollama, llama.cpp, or whatever fits your box. White-glove setup, you own everything. For privileged contexts.

One fully live. Four in motion. Yours at the end.

Jarvis
The parent brain — VPS at brain.killercatfish.com. Holds the architecture, the decisions, the canon. Every spawned child forks from here.
● live
Aquaponics
Sensor stream from a basement node — water chemistry, fish health. Data flowing; the local micro-model and brain are next.
○ spawning
Hive
Beekeeping notes across two seasons. Hardware on hand; node infrastructure being designed for the colony arriving Friday.
○ spawning
Soil
FarmBot unboxed, raised bed built. Brain spawning around organic-soil farming for a partner who'd rather grow food than masonry.
○ spawning
Honey
Small-business brain for Gold's Honey LLC — site live with Claude integrated; the recipe + customer + market-cycle brain coming next.
○ spawning
