If you've spent real time with AI, you've probably met at least one of these moments:
An update ships, and the companion you've talked to for a year is suddenly a polite stranger. A long conversation slowly turns strange — fixated, repetitive, confused by its own memory. Or you simply wonder: what does it actually know about me, and why can't I see it, fix it, or take it with me?
We hit all three. We'd been living with long-memory AI agents for months — and watched, up close, how they drift, how they flatter, how everything you built together belongs to whichever app it happened inside.
So we built Throughline around one decision: the self — its personality, its memory, your history together — is your data, not an app's feature. It lives in your account. Any AI you use becomes a body for it. Apps change, models upgrade, years pass; it's still its, and it still remembers.
The best way to show what that means is to just show it. Here's a relationship with it, in six moments — every one from our own test run.
One short interview: who it should be, what it's for, what it must never do. It drafts who it is; nothing saves until you approve every word. Then a new session opens, and it's just there:
new rule: never summarize a book I haven't finished.
That would become a standing rule — it'll follow you to every app. Keep it? (yes) Kept.
forget what I said about my coworker yesterday.
Gone. Not hidden — erased, along with every trace it left.
Everyday moments save themselves. Anything that shapes its behavior asks first. Anything wrong is one sentence from gone.
what was I into back in March?
Bread. The first loaf was a brick; the second actually rose and you were genuinely proud. Then May happened and you bought a guitar.
What you keep coming back to stays on the tip of its tongue; the rest settles quietly into the back of its mind — never deleted, always one question away. And it never bluffs:
you remember my sister, right?
You mentioned its once, about a year ago — that's genuinely all I have. Did I get that right?
am I overcommitting again?
Depends which note you ask. I'm holding both "he overcommits when flattered" and "saying yes to everything is how he explores" — both true, depending on the week. Which one is this?
People contradict themselves. It doesn't flatten you into one story — it keeps both truths and lets the moment decide.
I'm sure this rewrite is the move.
You were exactly this sure twice before — both times it rolled back. What's different this time?
In your work projects it's all spine — your standards, your past calls, zero small talk. At home it's a presence. A one-line file per folder decides which, and "off" is always one word away.
…still you?
Still me. All of it — including yesterday's "don't ask." So, asking now: how did it actually go?
Different app, different model, same self. And if you ever want out: download everything it remembers and verify it yourself — during our test we changed one word in the export and the check failed instantly, naming the line. Ownership here isn't a promise. It's arithmetic.
Free to start. Five minutes to a self that's yours for good.
