AI memory
Short facts the AI chat keeps about you between chats, stored on your computer.
Memory lets the AI chat remember things like "prefers metric units" or "writes in British English" from one chat to the next. The list is kept on your computer, one per profile, and every agent gets the same one: a fact saved while chatting with Claude is there when you next use Codex or 1zero AI.
How facts get saved
- You add one in Settings → AI → Memory → Memories with Add….
- You save a message: right-click something you wrote in the chat and pick Remember this.
- The AI asks: when you tell it to remember something, or state a lasting preference, it proposes a fact on a card. Nothing is saved until you allow it. This card shows even with Allow everything, and so does one asking to forget a fact.
- It learns from chats, if you turn on Learn from chats (off by default). When a chat ends, it reads only what you typed, never the pages or its own replies, and picks out lasting facts. With Review what it learns on, they wait for you to accept or dismiss them in Manage….
A saved fact shows as "Saved to memory" in the chat. It's used from the next chat on.
The AI is told not to save facts about health, money, politics, or religion, or anything from a page. Anything that looks like a card number, a one-time code, a password, or an API key is refused.
Settings
Settings → AI → Memory:
| Setting | Does |
|---|---|
| Use memory | On by default. Off, chats get no memory and the AI can't save to it. Your facts stay. |
| Learn from chats | Off by default. Picks facts out of finished chats. Each pass uses your agent's quota or 1zero AI credit. Needs Save chats on. |
| Review what it learns | Learned facts wait for you before they're used |
| Search past chats | The AI can look through your saved chats for something you said before |
| Memories | How many are saved, with Add… and Manage… |
| Delete all memories | Asks first. Saved chats stay. |
Manage… lists every fact with where it came from and when. Search it, edit or delete a fact, or right-click one to copy it or open the chat it came from.
To start a chat without memory, pick Turn memory off for this chat from the + in the prompt before your first message.
Limits
- A fact is at most 200 characters.
- You can keep 200 facts. Past that, delete some to save more.
- Memory isn't used in incognito windows.
- Clearing chat history doesn't touch memory, and deleting memories doesn't touch chats.
What leaves your computer
The list stays on your computer, and 1zero's website stores none of it. When a chat starts, the facts go to your agent's provider as part of the prompt, as your messages do.
Apps connected to the MCP server can read your memory only if you turn on AI memory there. They can't change it.
