Core by Prifina
Take yourself with you across AI.
Your Core keeps your information, context, preferences and AI learning together, so the AI and apps you choose can work from the same you.
Manage keys on your Prifina Account when connecting tools.
Information moves both ways. What you settle in one place can come back to your Core and be there in the next one, as far as you allow it.
(a) The problem
AI is splitting into pieces around you.
ChatGPT today, Claude tomorrow, a coding assistant at work, an AI Twin in public, Souvéa at home, and something new next year. Each one builds its own version of you, so you keep teaching the same things again.
Your Core solves that. It holds the person once, and the AI you pick works from it.
Teach once. Use everywhere.
- 1You tell ChatGPT never to use em dashes in your writing.
- 2It becomes part of your Core.
- 3Claude follows the same rule tomorrow.
- 4Souvéa writes the way you asked without being told again.
- 5Your agent applies it when it drafts for you.
That preference belongs to you, not to whichever assistant you happened to tell first.
(b) The loop
Your Core learns as you go.
01
Something happens
You say something, make something, connect a source or an app produces an event.
02
Your Core learns
It arrives with its source and history intact, so you can see where it came from.
03
Your AI can use it
Only the AI, agent or app you authorized, and only the part you allowed.
04
The result comes back
What was learned, decided or produced can update your Core and go on from there.
(c) A different kind of connection
Signing in proves who you are. Connecting your Core brings what you know.

Answers one question
It proves who you are and gets you in the door. Everything you build up afterwards stays behind that company's wall.
Connect
Brings your personal layer
You let an app or an AI work with the part of your Core you choose. Signing in happens along the way, but it is not the point. You can change or withdraw it later.
See what happens when you connect(d) What belongs in your Core
More than AI memory.
Your context
Who you are, your roles, the people around you and the circumstances that matter.
Your knowledge
Notes, documents and the things you have found out or settled.
Your preferences
How you write, how you want AI to behave and the rules that always apply.
Your work
Goals, projects, plans, tasks, decisions and what came of them.
Your agents
Their names, jobs, limits and instructions, kept as yours rather than an app's.
Your AI learning
Corrections and the things you teach your AI over time, kept in one place.
Your permissions
Which apps and agents reach which parts of your Core, and what they may do.
Your history
Where something came from, when it arrived, what changed and what is true now.
(e) One Core, whatever AI you choose
Souvéa, AI Twin, ChatGPT, Claude and your own agents.
Apps give you the experience. Agents do the work. Models supply the thinking. Your Core keeps the continuity underneath all of it.

Build for the person, not another silo.
Instead of an app with its own account and its own copy of the user, build an app that connects to a Core the person already owns.
