How Core works
Your single source of truth, not the original source.
Your email still lives in your mail provider. Your calendar still lives in your calendar. Core does not pretend your information started here. It keeps a working copy with the trail intact, so your AI can act on one coherent version of you.
Core
The persistent personal information and AI layer that belongs to you. It holds the current truth about you and what your apps, AI and agents need to work for you.
PIOS
The open architecture underneath Core. It defines how personal information is structured, how provenance is kept, how apps interact with a Core, how permissions work and how it all stays portable.
Core by Prifina
Prifina's hosted personal Core. You sign in with a Prifina ID and Prifina hosts and operates your Core for you.
Prifina ID
Who you are at Prifina: sign in, credentials, subscription and billing. Everyone has a Prifina ID, whether or not they have a Core. The ID opens products. It does not hold your personal vault.
Entity Core
A Core that belongs to a group — team, community, partner, or project. Same product as Organization Core. You join it with an invite on your Prifina ID. Its files stay there. Leaving it does not delete your personal Core.
The truth model
From where it came from to what is true now.
An email starts in Gmail. A meeting starts in a calendar. A conversation starts in ChatGPT. Those sources keep working. PIOS records what arrived, where it came from and when, and your Core keeps a truth copy that you and your AI can correct over time.
That is why an AI can rely on your Core without anyone pretending the information was born inside Prifina.
Original source
Gmail, Google Calendar, Drive, ChatGPT, a health app.
Raw information arrives
PIOS takes it in exactly as it came.
Provenance recorded
Where it came from, its id there, and when.
Truth copy in Core
A working copy your AI can read and reason over.
Corrections and learning
You fix it, add to it or an AI updates it.
Current truth
What is true for you right now, with the trail behind it.
What PIOS keeps for every piece
Permissions
Nothing reaches your Core by default.
Scoped
An app asks for parts of your Core, not all of it. You approve what it gets.
Recorded
Reads and writes are attributed, so you can see which app did what and when.
Reversible
Withdraw access at any point. The connection stops, your Core stays.
The learning loop
It is a loop, not an import.
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.
