AI Brains
An AI second brain that cites its sources.
A Claude Code + Obsidian system built around your documents, calls and research. It reads, links and answers, and it refuses to turn an unsourced number into a fact.
What’s inside
Six parts, one habit: check the source.
A vault you own
Plain markdown in an Obsidian vault on your machine or your repo. Open it without me, back it up, move it anywhere.
Ingest skill
Point Claude Code at PDFs, transcripts, web pages or notes. It writes linked wiki notes instead of dumping text into one file.
Ask with citations
Questions get answered from the vault, with the notes behind each answer linked so you can check them in one click.
Evidence ledger
Figures live as claims with an evidence class. A linter fails the build when a note asserts a number nothing supports.
Session memory
A hot index and CLAUDE.md conventions so a new Claude session picks up where the last one stopped, instead of starting cold.
Built for your work
Folder structure, templates and skills shaped around how you actually decide: clients, content, research or operations.
How it works
Drop a source in. Ask. Check.
You work in plain language. The skills handle where notes go, how they link and whether a figure has earned its place.

Brain types
Start from the one closest to your work.
Personal Brain
Founders, consultants and creators
Your research, reading, meetings and decisions in one place that Claude can reason over.
Marketing Brain
Marketers and content teams
Positioning, personas, keyword maps, brand voice and content rules, with gates that stop weak drafts.
Client Brain
Agencies and freelancers
One vault per client: calls, deliverables, metrics and decisions, so handovers stop losing context.
Early access
The first Brains are built one-to-one.
I’m taking a small number of early clients to build each Brain with, before packaged versions go on sale. Tell me what you’d want yours to remember.
- A 30-minute scoping call
- A vault built around your sources
- Setup, skills and a handover session
Questions
About the Brains
Do I need Obsidian and Claude Code already?
Obsidian is free to download. Claude Code needs a paid Claude plan or API access. I set both up with you during onboarding and document the setup inside the vault.
Where does my data live?
In markdown files on your computer or in a private repository you control. Claude reads the files you point it at in a session; the vault itself isn’t stored on my servers.
How is this different from Notion AI or NotebookLM?
Those keep your knowledge inside their product. A Brain is open files plus skills you can read and change, and it enforces evidence rules so the answers don’t quietly drift from their sources.
Can you build one for my team?
Yes. Team brains add shared conventions, a review step and training so people actually contribute. Tell me about the team in the form below.
