Live now · trusted by design

An AI that remembers you — in a vault only you can open.

AI is brilliant but forgetful. 9scroll gives it a lasting memory of you and your work — and locks every word with a key only you hold. We keep it safe. We can never read it.

All 9scroll ever stores

That's real encryption, happening in your browser right now. The server only ever sees the ciphertext on the right — only your key brings it back.

The other half · memory that survives

Close the chat. It still remembers.

Today's AI forgets you the moment a conversation ends. 9scroll gives it a memory that lives in your vault — so a brand-new session still knows you. Tell it something, wipe the chat, and watch:

Claude · session one has memory

Same memory, brand-new chat. The conversation was wiped — but your knowledge lived on, sealed in a vault only you can open.

How the encryption works

Your key never leaves you.

01 · on your device

Locked with your key

Your words are sealed before they ever leave your device. The key stays with you.

02 · on our servers

A box we can't open

We store and protect the locked box — but we hold no key, so we can never see inside.

03 · back on your device

Only you unlock it

Your key opens the box, on your device alone. No one in between ever reads a word.

Two levels of trust

Managed, or truly zero-knowledge.

Both use the same modern encryption (XChaCha20-Poly1305). The difference is who holds the key. Read the security brief for CFOs →

Managed

Encrypted at rest

Every value is sealed before it touches disk. A stolen database or a leaked backup is unreadable ciphertext. Frictionless — connect and go.

A disk dump or subpoena of our storage yields nothing readable.
Sovereign · zero-knowledge

Not even us

The key is generated on your machine and never leaves it. Even a full breach of our servers yields only ciphertext. The strongest guarantee there is — built for finance.

Our own tests fail the build if the server key alone could ever read your data.

Why it matters

Memory you own — across every AI.

You own it

The key is yours, not ours, not any AI vendor's. Leave anytime and take your memory with you.

Works with any AI

Claude, ChatGPT, and whatever comes next. One private memory beneath all of them.

It can't peek

Not "we won't." Can't. Even if ordered to, even if hacked — there's no key on our side to give.

Built for the Kingdom

Data stays home, private by law (PDPL), sovereign by design — the encrypted memory beneath every Saudi AI. And it works today.
