# Pages, charts and apps from your assistants

> When an assistant builds a page, a chart, a document, a table, an image, a video, a recording, or a small app, it shows up under the answer and opens beside your chat.

Sometimes an answer is something to look at, not just something to read. An assistant can publish what it built, and you open it right in StellarFirm, next to the chat.

## What an assistant can publish

| You see | What it is |
| --- | --- |
| Page | A web page, with a chart, a report, or a small tool in it |
| Picture | A drawing or a chart as a picture |
| Document | Formatted text, like a brief or a plan |
| Table | Rows and columns from a spreadsheet file |
| Data | Structured data, easy to read |
| Image | A photo or a graphic. You can download it |
| Video | A clip you can play, with controls and full screen. It waits for you to press play |
| Audio | A recording you can play, with its own controls. It waits for you to press play |
| LaTeX | A LaTeX document, like a paper, lecture notes, or a worksheet, shown as its source and a preview |
| App | A small program the assistant started on its own computer |

Each one appears as a card under the answer with its name, its kind, and who made it. Press **Open** and it opens in a panel beside the chat. You can drag the panel wider, make it fill the screen, or close it. One artifact is open at a time.

## Pages and pictures are kept apart from StellarFirm

A page an assistant built is its own work, so StellarFirm treats it as something to look at and nothing more. It runs in a closed box: it cannot see your account, your chats, or anything else in StellarFirm, it cannot send information to an address, and it cannot open other pages or windows. If a page tries to open another address anyway, the box is closed and you are told. It can draw, animate, and respond to clicks inside its own box. If a page needs a chart library, it can load well-known ones from one trusted library host.

Documents, tables, data, and images are shown as plain content. Large tables show their first rows and columns, and say so. A video or a recording plays in the panel and can be downloaded. Nothing starts playing on its own.

## LaTeX documents

A LaTeX document opens with a preview of how it reads, with its formulas drawn, and its source beside it. On a narrow panel you switch between **Preview** and **Source**; make the panel fill the screen to see both side by side. Press **Download** to save the file.

Where editing is switched on, you can change the source yourself. The preview follows a moment after you stop typing. Press **Save as a new version** to keep your edit: it appears as a new card next to the original, which stays as it was. If a save does not go through, the original is unchanged and you can still download your edit.

The preview is for reading. Pictures and a separate bibliography file are not shown in it, and a picture shows as a placeholder. To get a PDF, ask the assistant to make one on its computer and share it with you.

## Apps

An app runs on the assistant's own computer while you have it open. StellarFirm gives you a private address only after you press **Open**, and only you can get it. The app opens in the panel, and you can also press **Open in a new tab**.

- The computer keeps running while the preview is open, and a preview closes by itself after an hour.
- If the computer fell asleep, the panel says so. Press **Open again** to wake it.
- Closing the panel closes the preview.
- Apps come from the Coder, which is the assistant that is allowed to reach the internet for the packages it needs.
- Safari does not let a framed app keep its sign-in. If the app stays blank, press **Open in a new tab**.

## On your phone

The phone app shows the same cards under an answer. A file saves or shares from your phone. An app opens in the phone's browser. Where the phone cannot open something, the card tells you to open it in the web app.

## If you do not see them

Artifacts are rolling out step by step. If an assistant says it published something and no card appears, the feature may not be switched on for your account yet.
