What pal.fun is

Most consumer AI hands you a tool — a blank box that waits for a prompt and forgets you the moment the tab closes. pal.fun is built differently: it's an agentic platform for families — a pal that actually helps run the household. It reads the school calendar off a photo and drops the dates onto a shared calendar, remembers your family and your week, sets the reminders, and keeps the recipes, plans, and notes you make together so they don't vanish into a transcript.

These docs explain how it's built and why it works, because the how is the differentiator and we have no reason to hide it.

A pal that runs the life-admin

The point of a pal isn't to chat — it's to do the work a busy household never gets to. Snap a photo of the season's game times, a birthday invite, a summer-camp schedule, and your pal reads every date straight onto the calendar with reminders. Or skip the photo and just ask — "add the World Cup knockout games in my timezone" — and it looks it up, converts the kickoffs, and sets them. The dinner the kids actually ate, Saturday's practice plan, the trip itinerary: they land in a library you can find months later, not a scroll-back you never do.

It does this as a Someone, not a faceless assistant — it has a name it chose, a voice, a memory of you that grows. But the character is in service of the work: a pal you'd actually hand your week to. The capabilities page covers the calendar, library, and web access in detail.

One pal, the whole family

A pal doesn't have to be just yours. Set one up for your household and the whole family shares a single pal that knows everyone in it — each person with their own private chat, the pal keeping one shared memory of family life: the birthdays, the appointments, the recital on Thursday. Kids join on a device you approve; another adult joins by email invite as their own private account. Whoever sets it up holds the controls. See one pal, the whole household.

And you can see all of it

Here's the part most AI won't show you: the entire pal is readable. Its personality, the facts it's learned about you, its memory, its operating rules, the exact tools it can call — all of it lives in plain files you can open in a built-in viewer we call the glass box.

No hidden prompt, no opaque vector store, no mystery weights deciding what your pal knows about your family. If you want to know why your pal did something, you can go read the document that shaped it — and if something's off, you ask it to change it and watch the edit happen. That transparency is how a product that holds your family's whole life earns the trust to do so. Start with the glass box.

Why these docs exist

Two reasons. First, the architecture here is genuinely unusual — identity-as-markdown, context-as-code, persona-via-prose — and most companies that do anything like it keep it secret. We don't, because transparency is the brand. Second, writing down our safety posture and our data-custody promises isn't just good faith — it's accountable good faith. A stance you can read is a stance we can be held to.
