For you
Your AI can change. Your Core stays with you.
Core by Prifina is the personal layer underneath the AI you use. You build it up once, and it keeps working for you whichever app you open next.
Stop repeating yourself
The next assistant already knows your projects, your history and how you like things.
Pick a better AI whenever one shows up
Switching apps costs you nothing, because what you built up is not inside the app.
Your agents move with you
The name, the job, the rules and the limits are yours. Change the runtime, keep the agent.
You decide what each app sees
Give access to one part, not everything, and take it back in a click.
You can see where things came from
Your Core keeps the trail, so you can check what an AI is working from and correct it.
You can leave
Export your Core, move it to another compatible provider or run your own.
A normal day
Same you, three different AI.
Morning
You plan the week with Souvéa. The decisions land in your Core, not in a chat you will never find again.
Afternoon
You switch to Claude for a long document. It already knows the project, the tone you use and what you decided this morning.
Evening
Your AI Twin answers a question for someone else using only the part of your Core you allowed it to use.
Where the account comes in
You create a Prifina account and Prifina hosts and runs your Core. The account handles signing in, permissions, subscription and billing. Your Core holds and manages your personal information and AI context.
