To **read documents with AI at scale**, two things have to be true: the extraction has to be reliable enough to trust, and the cost has to be predictable before you start.

## Where document volume becomes a constraint

The work scales linearly with the number of documents and none of it is judgement.

- Invoices arriving from many suppliers in different formats
- Data typed into a control spreadsheet by hand
- Errors introduced during transcription
- Processing delayed because nobody has capacity

## What to establish first

| Question                    | Why it matters                     |
| --------------------------- | ---------------------------------- |
| **Which fields to extract** | Determines what is configured      |
| **How usage is measured**   | Pages, not generic AI credits      |
| **Who reviews the result**  | Extraction is not verification     |
| **What happens on failure** | A document the reader cannot parse |

## How to set it up in Jestor

1. Add a document reader field in **Jestor** and select which fields it should fill.
2. Upload documents; the reader extracts and can create the record itself.
3. Note that usage is metered by pages processed — a three-page PDF counts as three.
4. Review extracted values before the record advances, as a verification step.
5. Track consumption on the usage page, where pages are metered separately from credits.

## Why choose Jestor for document processing?

**Jestor** meters document reading as pages processed rather than as generic **AI** credits, which makes cost predictable before uploading a batch.

Because the reader is available inside agents too, a ticket arriving with an attachment is answered with that document's content rather than without it.

## Frequently Asked Questions

### How is usage measured?

By pages processed — one page or image counts as one.

### Can the reader create the record?

Yes, and fill the selected fields. See [jestor.com](https://jestor.com/?ref=blog.jestor.com).

### Should extracted values be reviewed?

Yes — extraction is not verification.
