Memory · Recalled verbatim · Aug 13, 2023 · Stored on your device

You said it once, years ago. You never filed it anywhere. It never forgot.

More than memory.
A complete assistant.

Chat with memory

Ask anything. Your assistant remembers every conversation—no context windows, no starting over.

Instantly recall your history

Find anything you've ever said or learned. Instant recall across years of conversation.

Voice input

Talk naturally. Your words are transcribed and remembered just like text.

Analyze documents

Drop in files. The assistant reads, remembers, and can reference them later.

Built for people tired of
repeating themselves to their AI.

Say it once

Tell it something a single time. It is kept, word for word. You never have to explain it again.

Never start over

No new chats, ever. Pick up a thought from months ago and it keeps going, like you never stopped.

Nothing to manage

No folders, no notes files, no models to choose, no limits to watch. You just talk, and it remembers.

Only yours

Your memories stay on your device. We cannot read them, train on them, or sell them. So say anything.

You talk.
It remembers.

Tell it anything. Thoughts, facts, the small moments you want to keep. Each one is sealed with a timestamp and stored on your device. When you want it back, you just ask.

Recall is instant and local. Your memories never leave your device. New conversations are processed under zero data retention and stored immediately on your device as memories.
