How the assistant uses your past chats
Every new chat starts without the conversations before it. The assistant can still look back, through a built-in connector that searches your own chat history. This page explains how that works, what day notes are, and what happens when you delete a chat.
Asking about earlier work
Without help, an assistant forgets everything between chats. You'd explain the same background again, even when the assistant helped you work it out last week.
Knowledge Worker Agent includes a connector called recall for this. The assistant can use it to:
-
List your chats from a period, with their names, dates, and what each one started with.
-
Search the text of your messages, and see which chat each match came from.
-
Read the messages of one chat, from the start or from the most recent.
So you can ask things like "What did we decide about the schema last week?" and the assistant can find the chat and read it.
To search your chats yourself, select Search chats in the sidebar. For more information, see Search your chats.
Temporary chats are left out: the assistant doesn't list, search, or read them. For more information, see Use a temporary chat.
The recall connector is on by default, unlike other connectors. It isn't a third-party service: it reads your own chat history in your workspace, and it can only read, never change anything. To turn it off, turn it off in the Connectors dialog. It stays off. For more information, see Manage connectors.
What the assistant finds becomes part of the conversation, and is sent to your model provider like anything else it reads.
Complete answers, or clearly partial ones
A long chat can hold far more text than the assistant can take in at once, so each lookup returns a limited amount. Every answer says how much there was, and whether some was left out. The assistant can then ask for the next part, or narrow the search, instead of treating a partial answer as the whole story.
Day notes
A chat's name and first message describe how it started. A chat that runs for weeks can end up somewhere else entirely. Day notes fill that gap: a short, factual note of what was worked on in a chat on one day.
Day notes are written in the background:
-
For chats where they help: a chat with at least 20 messages, or with messages on more than one day, gets notes. A short chat from one day is already described by its name and first message.
-
Only for finished days: a note is written once a day is over, so it describes the whole day.
-
A few at a time: up to 25 notes are written every six hours, newest days first.
-
On a small model: notes use the small model your workspace names for background jobs. If it names none, a low-cost model from an available provider is used. If there's none of either, no notes are written, rather than spending a larger model on them.
When the assistant lists your chats, it sees their day notes too, and the last day the notes cover.
Deleting a chat
Deleting a chat deletes its messages. Its day notes are kept by default, marked as describing a deleted chat, and the assistant can still find them. Clearing out old chats then doesn't erase the record of what you did.
Sometimes you delete a chat because of what's in it. So when a chat has notes, deleting it asks whether to delete the notes too. For how, see Delete a chat.
