# Documents in Studio

* **Documents, a new page in Studio.** Pick an environment, a collection and a document, and see what Captain actually indexed from it. Every chunk is listed in order with its type and its page. The text is rendered the way the parser produced it, so a heading looks like a heading and a table looks like a table. Open any chunk to see its stored text and its metadata.
* **Chunks as a table.** Filter by chunk type or search the loaded chunks. Markdown files have no layout types, so they get no type column. A Rendered / Raw switch shows the stored text exactly as it is.
* **Figures.** Every figure the parser extracted, grouped by page, each with a link to the chunk it belongs to. These are the same crops the [asset URLs](/reference/v3/document/asset-urls) endpoint returns.
* **Edit metadata in place.** Change the custom metadata on a document or on any chunk directly from the page. Saving replaces the whole set, the same way the [document](/reference/v3/document/metadata/replace) and [chunk](/reference/v3/documents/chunk/metadata/replace) metadata endpoints work, so what you see is what your queries filter on. You can delete a document here as well.
* **Linked to the rest of Studio.** Open a document from its row on Home. From the document, jump to the collection's feed on Activity or to the job that indexed it. From a query in Activity, open the exact chunk it cited. Every view has its own URL, so a link to a document or a chunk survives a reload and can be shared.
