An AI that remembers you the way a person would.
KAPEX is the memory underneath AI apps, for the people who build them. It isn’t open for signup yet.
What it feels like
Three short examples, each with someone coming back to an app that uses KAPEX.
- It keeps what you would want a friend to keep.Names, plans, the things you care about. What it hands the app is a short note, not a transcript.
- It asks before it brings something up.Ask it to leave something alone, and it stops handing that to the app.
- You can see what it remembers about you, and change it.Keep it, hide it, fix it, or delete it.
First week in a new apartment
Moved into the new place. Boxes everywhere and I already miss the old neighborhood.
Big change. Do you want to talk about the old neighborhood, or leave it for now?
Leave it. Tell me a decent way to unpack a kitchen.
Plates and one pan first, so you can eat tonight. Everything else can wait a week.
What happens a month later
A month later
Finally cooked a real dinner here.
What the app was handed
A note KAPEX wrote for the app
- Background. Moved into a new apartment, unpacking the kitchen first.
The old neighborhood isn’t in the note, because the person asked for it to be left alone.
Behind it, the app heard “leave it” and told KAPEX to leave the old neighborhood alone.
A returning customer
Customer: Hi, it’s me again about the coffee order. Still hasn’t turned up.
App: That’s the dark roast we re-sent after the address mix-up. Tracking shows it stuck at a sorting hub since Tuesday.
App: Want a fresh bag sent to your office today, or should I chase the hub first?
Customer: Office, please.
The customer didn’t have to tell the story twice.
Evening calculus class
Student: Back again. Product rule today.
App: Last time the chain rule clicked when we used nesting dolls. Want a picture for this one too, or straight to examples?
Student: Picture first.
App: Think of a rectangle where both sides are growing. The new area arrives in two strips, one from each side growing while the other holds still.
It started from what helped this student last time.

How it works
KAPEX sits between an app and the AI model behind it, and does its part just before and just after each reply.
- Before the app answers you, it asks KAPEX what matters about you for this reply.
- KAPEX hands back a short note, and the app puts it in front of the model.
- After the reply, the app sends KAPEX what you said and what it answered, and KAPEX picks out who and what it was about.
And you can open what it keeps and change it. The model itself doesn’t change, so an app can switch models and keep what it remembers about you.
What you control, and what is still missing
The controls are built into KAPEX, and the app decides how they look on screen.
What this app keeps about you
-
Moved to a new apartment. Asked not to talk about the old neighborhood.

Keep Hide Fix Delete
Written to show the intent, not captured from a running system.
Hiding a line keeps it on your list but stops KAPEX handing it to the app. Deleting a line removes it.
There’s no app you can try it in yet.
All the controls, and what delete doesn’t cover yet

Where it stands
Last reviewed October 12, 2026
- Built and tested: the two calls around each reply, and the controls on the control page.
- Not running: the hosted sandbox, self-service signup, and any public endpoint.
- No launch date is set, and nothing is for sale yet.
Who it’s for
Apps people come back to, like a help desk, a tutor, a journal or a coding assistant. If your app is one conversation and done, you don’t need this.
Building on it
KAPEX is a container your app calls over REST, just before each reply and again after it. The developer page has both calls written out, and says what runs today.
