# Inspect Foundry output

> Review extracted text, chunks, and retrieval readiness from a document

export const DocImage = ({src, alt, width, caption}) => <Frame caption={caption}>
    <img src={src} width={width} style={{
  padding: "8px",
  boxSizing: "border-box"
}} alt={alt} />
  </Frame>;

Open a document in **Knowledge** to compare the original with the result produced by a refinery. The original stays on the left and **Foundry output** appears on the right.

<DocImage src="/images/docs/knowledge-detail-ko.png" alt="Document detail with the original on the left and Foundry output with extracted text and chunks on the right" />

## Open a document

Double-click a document in Knowledge. The breadcrumb shows its folder path, while the header shows the document type, size, and last updated date.

* **Original** previews the uploaded file. Select **Open** to view the source file in a new tab.
* **Metadata** shows the document's identifiers, location, dates, and tags.
* **Foundry output** shows the result of the refinery connected to the document.

## Review the output

The top of **Foundry output** shows the connected refinery and the number of chunks it produced.

### Extracted and normalised text

Expand **Extracted / normalised text** to review the text produced before chunking. Use it to check whether headings, tables, and paragraphs were extracted as expected.

### Chunks

Expand **Chunks** to inspect what retrieval can use. The summary shows:

* the total number of chunks
* how many chunks are embedded
* how many chunks are connected to the KG

Search within the chunks, select one to read its full text, or use **Expand all** to open every chunk. Each row shows its chunk number, status, preview, and character count.

<Tip>
  Compare a suspicious chunk with the original on the left. If text is missing or split poorly, adjust the refinery in [Foundry](/build/foundry/overview) and run it again.
</Tip>

## Run a refinery again

Select the refinery name to choose another existing refinery in the workspace. Select **Run again** to process the document with the selected refinery. The Foundry output updates when the run finishes.

<Note>
  Running a refinery again replaces the displayed output for this document. It does not change the original file.
