# Memory and context

> How the assistant draws on your earlier chats, and how to see and control what it used.

A new chat does not start from nothing. Before answering, the assistant looks
through what you have already discussed and pulls in the few pieces that relate
to your message.

Three different things get pulled in, and it is worth knowing which is which:

* **Memory** — durable facts learned about you. "Prefers TypeScript", "works in
  Central European Time". A handful of short statements, not transcripts.
* **Excerpts** — actual passages from earlier chats, quoted back because they
  resemble what you just asked.
* **Knowledge-base documents** — passages from the files you added to a
  project's **Knowledge base**, pulled in when they relate to your message.
  These are read inside that project's chats and nowhere else: a knowledge base
  never reaches a chat outside the project it belongs to.

All three are scoped to you. Nobody else's chats are ever read, whatever their
sharing settings say, and no project's knowledge base is ever read from outside
that project.

## Seeing what was used

Above the assistant's reply you will find a line like:

> Recalled 3 items

Open it and every item is listed with where it came from. An excerpt carries the
chat's title, the date, and a relevance score; a knowledge-base document carries
the filename it was read from, and a score; a memory is shown as the fact itself,
with its score. If a reply surprises you, this is the first place to look: it
shows exactly what the assistant had in front of it.

The line only appears when something was actually recalled. No line means the
answer came from the current conversation alone.

<Note>
  Recall costs nothing extra. Finding the excerpts uses one small embedding
  request per message, which is already part of what you pay for the message.
</Note>

## Your memory list

**Settings → Profile → Memory** lists everything the assistant has learned
about you, with the chat each fact came from and whether it applies everywhere
or is sealed inside one project. Delete any single fact, or **Clear all**.
Deletion takes effect immediately — the next message will not see it.

An empty list usually means exactly what it says: nothing durable has come up
yet. Memory is deliberately conservative — it records standing facts, not what
you happened to ask about last Tuesday. Short chats, one-off questions and
purely technical back-and-forth often produce nothing at all, and that is
normal rather than a fault.

## Keeping a project to itself

Some work should not draw on the rest of your account, and should not leak into
it either. Every project carries a **memory scope** for that, on the project
menu in the sidebar:

| Scope            | What the project can read                         | Who can read the project                                                 |
| ---------------- | ------------------------------------------------- | ------------------------------------------------------------------------ |
| **Default**      | Memory and chat transcripts from your other chats | Chats outside the project can use what it learns and what was said in it |
| **Project only** | Only its own memory and its own transcripts       | Both are hidden from every chat outside the project                      |

`Project only` isolates in **both** directions. A project set that way neither
reads from the outside nor contributes to it.

A project's **Knowledge base** does not depend on this setting. Its documents
are always confined to the project they were added to — readable by that
project's chats, invisible to every other chat, on either scope.

<Warning>
  Changing the scope does not move memories that already exist, and moving a
  chat into or out of a project does not move its memories either — each keeps
  the scope that was in force when it was learned.

  Chat transcripts behave differently on purpose: they follow the chat. Move a
  chat into an isolated project and what can be quoted from it moves
  immediately.
</Warning>

## Searching your chats

The **Search chats** box in the sidebar looks at both the words you type and
what your chats are *about*, so a search for "rate limiting" also finds a chat
that only ever said "throttling". Results respect sharing — you only see chats
you have access to.

## Steering recall deliberately

Recall follows resemblance, which is not always what you want. When you know a
past thread matters to the conversation you are in — even though nothing you
type will resemble it — pin its topic to the chat. See
[Topics and the graph](/playground/topics-and-graph).
