Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

# Artifacts

> An artifact is a file Claude saves into the project: a figure, processed dataset, report, notebook, or other output.

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.

## Working with artifacts

Click a linked file in the conversation to open it in a tab beside the chat. 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 every artifact in the project. From an artifact's menu you can: Open, Open beside session, **View in context**, **Provenance**, Versions, **Copy link**, **Star**, **Rename**, **Download**, or **Delete**. Renaming doesn't break links. **Delete** removes all versions permanently.

Files you attach or drop into the composer 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. Images, PDFs, HTML, and tables 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.
