# Artifacts in Claude Science

> Artifacts in Claude Science are files Claude saves into a project, such as figures, datasets, and reports. Open, version, trace, and delete them.

In Claude Science, an artifact is a file Claude saves into the project: a figure, processed dataset, report, notebook, or other output. Artifacts are stored on your computer in the app's data folder and persist until you delete them. Other files Claude writes during a session are temporary and are cleared a few hours after the session ends; ask Claude to save a scratch file if you want to keep it.

<Note>
  If you use artifacts in a claude.ai chat rather than the Claude Science app, see [What are artifacts and how do I use them?](https://support.claude.com/en/articles/17153992-what-are-artifacts-and-how-do-i-use-them) in the help center instead.

## Working with artifacts

Click a linked file or a figure in the conversation to open it in a tab beside the chat. Ctrl/Cmd-click opens it full screen. HTML artifacts have zoom controls, including fit to width; images zoom up to their native resolution. Open **Files** in the sidebar for a searchable grid of the project's artifacts. From an artifact's menu in **Files**, you can choose **Pin**, **Hide**, **Open in Artifact Viewer**, **View in context**, **Provenance**, **Copy link**, **Rename**, **Download**, **Export Metadata**, **Export to Cloud**, or **Delete**. Renaming doesn't break links. **Delete** removes all versions permanently.

Files you attach or drop into the composer, and images you paste into it, are listed under **Your uploads**.

To copy artifacts outside the app, use **Download** for a single file, or open the project's folder under \~/.claude-science and copy the files directly.

## Versions

When Claude saves the same filename again in the same session, the artifact gains a new version. You can also edit text-based artifacts (Markdown, code, plain text) directly: click **Edit content**, make changes, and **Save** to create a new version. In a Markdown file, you can click a plain-text cell in the body of a table and type, and the app saves the change as a new version. Images, PDFs, HTML, and table files such as CSV can't be edited in place.

When an artifact file is open, a version stepper and a diff toggle appear. In diff mode, you can choose which earlier version to compare against; the previous version is the default. Older versions are read-only; to restore one, ask Claude to save it again. Links Claude puts in the conversation point to the specific version that existed at the time.

## Provenance

Every artifact version records how it was made. Open **Provenance** from an artifact's menu to see five tabs:

* **Messages**: the conversation around the save.
* **Code**: a reproducible script, downloadable as a script or notebook.
* **Execution Log**: every command that ran.
* **Environment**: the environment name, language version, and every installed package with its version.
* **Review**: findings from [the reviewer](/docs/claude-science/the-reviewer).

The **Execution Log** is the authoritative record of what ran. If the **Code** tab and the log disagree, trust the log.

## Deleting artifacts

Deleting a session keeps its artifacts and their provenance. Deleting a project deletes all of its sessions, artifacts, and project-scoped memory.
