# In-app document viewer

Loan documents open in a full viewer inside the platform. Reading past the first page no longer requires downloading the file, and the viewer is no longer confined to one screen.

## Where it opens

- The preview modal on the loan **Documents** page, in Document Manager.
- **In place on the Tasks screen** — a document attached to a task opens where you are, without leaving the task.
- In the **AI Assistant**, in the cited-document window, so you can read the source behind an answer directly.
- In the **mobile app**, which has its own in-app viewer rather than handing the file to the phone.

The same viewer powers PDF previews in the BIG AI Knowledge Base, so both document libraries behave the same way.

## What the viewer does

- **Every page, scrollable**, with page navigation and a counter that follows your scroll position.
- **Zoom from 50% to 300%** for fine print.
- **Working internal links** — a document's own table of contents jumps to the right page.
- **Large files stay responsive** — an 800-page file opens as quickly as a two-page one.

## Controls in Document Manager

The Document Manager viewer adds **rotate**, **drag to pan**, **fit to page** and **print**. These are what you want for the phone photos borrowers often submit: straighten a paystub that came in sideways, fit a wide scan to the window, then magnify and move around it. The image stays centred as you rotate and zoom.

## Who uploaded it

The creator's name appears on document cards and in the preview. Documents that arrived from the LOS show a neutral placeholder instead of a user name.

## If a document will not preview

The document is shown without a preview rather than returning an error. If the file itself appears to be missing or wrong, contact support with the loan and the document name.
