Memory

Memory settings#

Manage memory in Settings → Memory. A document in Files isn’t a memory, and nothing you write in a chat becomes a memory unless these settings are on:

• Dynamic Memory — Chat can save and update facts.
• Use saved memories — Chat can include relevant saved facts in replies.
• Chat History Memory — Chat can search your finished text conversations for context. Turning this off doesn’t remove any chats from the sidebar.

Each setting works independently. For example, you can keep saved facts without using them, or use earlier chats without saving new facts.

When Chat saves or updates a fact, a memory chip appears on that message, sometimes with Undo. To change an older fact, edit it in the memory list.

Project and Agent memory#

Each project has its own Dynamic memory switch in Settings → Projects. Facts saved in a project are labeled with that project in the memory list, alongside your global facts.

An Agent’s Memory setting can follow your account, be read-only, or be off. With read-only, the Agent uses saved facts but doesn’t save new ones. With off, the Agent doesn’t use memory. See Agents.

Code tasks aren’t added to this list automatically. See Memory in Code.

Edit or delete a fact#

Filter Memories by Scope or Tag. Each fact has Edit memory, Mark verified, and Delete memory. Before it deletes a fact, Chat asks Forget this memory? A fact can have up to five tags.

Chat history#

Chat History shows how much of your history is searchable, and has a Wipe button. Wipe deletes the search index and keeps your conversations. If you turn Chat History Memory back on, it indexes new messages only. It doesn’t restore a wiped index.

You can also choose the memory search model. If you change it, your facts and history are reprocessed in the background, and search results may be incomplete until that finishes.

Sidebar search and memory are separate. Search finds a chat by its title. Memory adds context to a reply.
