# Saving, Versions, and Access

> Save notebook versions, review saved results, and understand shared editing

A live editing session and saved notebook results serve different purposes. The editor lets one user run and change the notebook; saved results let other users review it without taking the editing session.

## Save Changes

While editing, click **Save Changes** in the notebook header. **Unsaved Changes** indicates that the current session has edits not yet saved as a version.

Saving changed source creates a numbered version. If the source has not changed, the app reports **No changes to save** and does not create a duplicate version. The assistant can also save versions, which appear in the same history.

Saved results are rendered from the saved notebook and may take time to become available. They are not a live view of another user's in-progress work. If rendering is pending or unavailable, the read-only view can show source code instead of rendered outputs.

> [!TIP]
>
> Save before leaving an investigation or sharing its results. Cell execution and the editor's file state are separate from the platform's saved version history.

## Switch versions

**1. Save work you want to keep**

Click **Save Changes** before switching if you want to preserve current edits.

**2. Open the version selector**

In the header beside **Save Changes**, open the version selector and select a saved version. It shows **No versions** until a user-facing version has been saved.

**3. Confirm if there are unsaved edits**

**Discard unsaved edits?** appears when switching would discard changes. Choose **Cancel** to keep working, or **Discard and switch** to continue.

Switching makes the selected version active and restarts the editing session from that source. It does not add a new history entry or delete later versions. Saving new edits after switching creates a new numbered version.

## Review saved results or edit

Reopening a notebook with saved results normally opens the read-only result view. Click **Edit notebook** to enter the editor when it is available. A newly created notebook with no saved results may open directly in the editor for its creator.

Only one user can hold the editing session at a time. If someone else is editing, the banner says **Read-only · another user is editing**. You can review the saved version. When the session becomes available, click **Edit notebook** to continue; reading saved results does not take the session from another user.

## Organization access

New notebooks and templates are visible within the organization where they were created. Other users with access can review them and edit their content when the editing session is available. Notebook source and saved results should therefore be treated as organization-visible material.

| Action | Who can do it |
| - | - |
| Review an accessible notebook and saved results | Users with access in the organization |
| Edit content, save versions, or switch versions | A user with access holding the editing session |
| Rename or delete | The notebook's creator |

Keep credentials out of notebook source. The [SDK client is authenticated automatically](https://docs.atomscale.ai/platform/reference/notebooks/working.md#access-atomscale-data).

## Rename or delete

The creator can right-click a notebook in the Analysis sidebar to rename or delete it. While editing their notebook, the creator can also click its title to rename it.

To delete from the right sidebar, select **Settings**, find **Danger zone**, click **Delete Notebook**, and confirm. Deletion permanently removes the notebook and its version history and ends its editing session. Deleting a template does not delete notebooks previously created from it.
