# Personalization & Memory

> Set persistent preferences and project-specific instructions

Biomni uses conversation context, personal instructions, and project settings at
different scopes. Choose the narrowest scope that fits the instruction.

## Conversation context

Within a task, Biomni can use earlier messages, attached files, and generated
results. Keep follow-up refinements in the same task:

```text theme={null}
Use the same filtered cohort, but stratify the result by treatment arm.
```

Start a new task when the goal or evidence boundary changes substantially.

## Personal instructions

Open your avatar menu and choose **Personalization**, or open the
Personalization section in Settings. Add durable preferences such as:

* preferred programming language;
* desired figure or report format;
* terminology and units to use; or
* response conventions you want across tasks.

Personal instructions are stored for your user in the active workspace and are
included when Biomni starts work. You can edit or remove them at any time.

<Tip>
  Write preferences as direct instructions: “Use R for statistical analysis” is
  clearer than “I sometimes prefer R.”
</Tip>

## Project settings

Use **Settings → Projects** for context or instructions that apply only to one
project. Project settings include:

* project context;
* ordered custom instructions; and
* auto attached Skills for the first message of new tasks.

Project instructions are more specific than personal instructions. Changes are
captured by new tasks and do not rewrite existing conversations.

## What not to store

Do not put passwords, API keys, access tokens, private keys, or other credentials
in personal or project instructions. Use approved connection and secret-management
flows instead.

[Projects & Drive](/features/projects-and-drive).
