# Preview & refine in chat
Play your animation in Claude or ChatGPT, comment on moments, send the notes to your AI agent, download an MP4, or open it in Lottie Creator.

Creator MCP shows your saved animation inside the conversation in a **preview card**. The card plays the animation, lets you pin comments to a moment and send them to your AI agent, exports an MP4, and opens the animation in Lottie Creator. Comments are notes for the agent: the agent applies them, and nothing in the card changes your animation on its own.

## Where it works

The preview card needs a client that supports MCP Apps. **Claude** and **ChatGPT** both work. Set them up with the [no-terminal steps](/en/developers/creator-mcp/connect#claude-and-chatgpt-no-terminal).

In clients without MCP Apps support, `creator_preview` is not listed. Ask for filmstrips, still images, or an MP4 to watch the motion at playback speed.

## Watch it play

Ask your agent:

> Show me first-loop playing.

The agent opens the card with `creator_preview`, and the saved animation plays in a loop. Click the picture to pause or play, and drag the time slider to move through it. If your client allows it, the fullscreen button enlarges the card.

## Comment on what to change

<Steps>
  <Step title="Pin a comment">
    Select **Comment**. Playback pauses at the current moment. Click the picture to mark a point, or drag to mark an area. The card names the objects under your mark.
  </Step>

  <Step title="Write your note">
    Type what should change in **What should change here?** and select **Add comment**. Move to another moment and add more comments if you need them.
  </Step>

  <Step title="Send them to chat">
    Select **Send to chat**; the button shows how many comments you're sending, such as **Send 2 to chat**. Your comments go into the chat as one message, with each comment's time and what it points at. Some clients send it straight away; others put it in the message box for you to send.

    The agent edits the animation to match. Ask it to show the animation again to see the new version. Once the card has no unsent comments or running export, it collapses to one row that says it was replaced.
  </Step>
</Steps>

<Callout type="info" title="Comments stay until they are sent">
  If the card can't send, your comments are kept; try again. The card holds up to 32 comments. If your notes are longer
  than one message allows, the card sends what fits and keeps the rest for the next send.
</Callout>

## Download an MP4

Select **Download**, choose a **Size** (Original, Small, Medium, Large, 4K, or a custom size) and a **Frame rate**, then select **Export MP4**. The card shows encoding progress and lets you cancel. When the file is ready, select **Download**, or **Copy link** to copy a temporary download link. Exporting from the card does not change the animation.

If the card says **Video download isn't available right now.**, ask the agent for the video in chat. For other formats, see [Export & save](/en/developers/creator-mcp/exports).

## Edit in Lottie Creator

Select **Edit in Lottie Creator** to save the animation to your LottieFiles workspace, then select **Open in Creator** to open it there. The first save creates a file in your Drafts project; later saves from the same animation add a new version of that file. The save uses the animation as last saved, without your unsent comments. The button appears when your connection can save to your workspace and your client can open links. See [Open in Lottie Creator](/en/developers/creator-mcp/exports#open-in-lottie-creator).

If the card does not appear or your comments did not reach the agent, see [Troubleshooting](/en/developers/creator-mcp/troubleshooting#previews-and-edits).
