What your AI should know — and follow.

CtxCore Brain is a company brain for your AI. It collects the rules your company really works by. The right person approves each one, and then every AI you use gets them.

Right now, your rules are everywhere.

Some live in people's heads. The rest are spread over a wiki nobody updates, a Slack thread from March and five AI prompts that already contradict each other.

We pull them out, one Rule at a time.

We run short voice interviews with the people who know and import your wiki and documents. Every Rule gets a statement and a reason.

Every Topic has an Owner.

Returns, tone of voice, discounts: each area belongs to someone. A Rule counts once its Owner publishes it. Until then it's a draft.

Skills put the Rules to work.

A Skill like “answer a complaint” uses Rules from several Topics. When one of those Rules changes, the Skill uses the new version.

When two Rules disagree, both Owners hear about it.

CtxCore Brain searches for contradictions and shows them to the people responsible. Neither Rule wins by default.

Your AI only sees what's been published.

Claude, ChatGPT, Copilot and your own tools read the same Context over MCP. Each answer can show which Rule it followed, in which version, and who approved it.

Your AI is only as good as the rules it follows.

We build it with you

We interview your people, import what you already have and set up the first Topics with your team, at a fixed price.

We keep it current

New decisions come in as Proposals. Owners approve them, and nobody has to tidy the Context up by hand.

It works with the AI you already use

You don't have to roll out another assistant. Your tools connect over MCP and read the same approved Context.

Common questions

In short: a second brain for your company that doesn't collect everything. It decides what applies.

Is CtxCore Brain a second brain?

Yes, one for your company, with one difference. A personal second brain collects everything you might need someday. CtxCore Brain only holds what applies: every Rule has an Owner who approved it, and your AI only reads published Rules. A second brain remembers. This one decides what counts.

How is it different from a knowledge base or wiki?

A wiki stores documents and hopes someone reads them. CtxCore Brain stores Rules: short statements with a reason, an Owner and a version. It flags Rules that contradict each other and always gives your AI the current version.

Does it work with ChatGPT, Copilot and Claude?

Yes. Claude, ChatGPT (Business and Enterprise) and Microsoft Copilot connect over MCP (Model Context Protocol) and read the same approved Context. You can connect your own tools and agents the same way.

Can we bring what we already have?

Yes. We import wikis, documents and presentations, and Confluence can stay connected. Changes made there come in as Proposals, not as rules that apply straight away. Whatever is missing we collect in short voice interviews with the people who know.

Where is the data stored?

With us, on AWS in the EU. Each customer gets their own instance, and we act as your data processor under a data processing agreement.

What does it cost?

Setup is a fixed price that depends on how many Topics and people are involved. Upkeep runs as a monthly subscription.

Who is CtxCore Brain for?

Companies from about ten people that already use AI and notice it doesn't know their rules.
