# Extraction review

> Approve or reject the transactions that Matcher extracts from a PDF document before they enter a source, in the Extraction Review queue of the Matcher module.

Matcher can read a PDF document, such as a bank statement, and propose the transactions it finds. These proposals are candidates. A candidate does not enter reconciliation until a person approves it. The **Extraction Review** screen of the Matcher module in Lerian Console is the queue where you approve or reject them.

> [!NOTE]
>
> Document extraction is not available in every environment. When it is off, the screen shows a message instead of the queue.

## How a review starts

***

**1. Extract from a document**

In the **Sources** tab of a context, use the **Extract from a document** action of a source. Upload one PDF document. See [Context sources](https://docs.lerian.studio/en/products/matcher/ui/context-sources.md).

**2. Matcher reads the document**

Matcher uses AI to read the document and propose candidate transactions. Matcher sends a capped slice of the document's text layer to the language-model provider Lerian configures for your environment. When the PDF has no text layer, Matcher sends the PDF itself. Matcher queues the candidates as one review with the **Pending review** status.

**3. Open the review**

The dialog shows the number of candidates and an **Open review** link. You can also open the review later from the queue.

## Accessing the Extraction Review screen

***

Click **Resolve → Extraction Review** in the Matcher sidebar. The screen shows the **Active context** that you select in the Matcher sidebar. To see another context, change the **Active context**.

## The review queue

***

The queue shows the reviews of the context, 25 per page. Use **Previous** and **Next** to move between pages. The **Status** filter shows **Pending review** reviews by default. You can also show **Approved** or **Rejected** reviews.

| Column | Description |
| - | - |
| **Document / source** | The short ID of the source that the document belongs to. Click it to open the review. |
| **Status** | The review status. |
| **Candidates** | The number of candidate transactions in the review. |
| **Created At** | When Matcher created the review. |

## Reading a review

***

The review page shows each candidate as a card, **Candidate 1**, **Candidate 2**, and so on. A badge on the card shows how Matcher read it:

* **Text layer**: the candidates come from the text layer of the PDF.
* **Vision · lower trust**: an AI model produced the values from the document itself. Check these candidates with more care.

Each field of a candidate shows the value that Matcher read and an **Extraction confidence** meter. When known, it also shows the page and region of the value.

You cannot edit a candidate. You approve or reject the review as a whole. To go back to the queue, click **Queue**.

## Approving a review

***

1. On a **Pending review** review, click **Approve extraction**.
2. In the **Approve extracted transactions?** dialog, click **Approve and commit**.

Matcher sends all the candidates of the review to its source as one import, the same way it imports a file. After a successful approval, the review status is **Approved** and the review shows the ID of the import job. The import job also shows in the **Import jobs** table of **Operate → Operational History**. See [Operational history](https://docs.lerian.studio/en/products/matcher/ui/operational-history.md).

If the context has **Auto-match on upload** turned on, the import starts a match run. You cannot undo an approval.

## Rejecting a review

***

1. On a **Pending review** review, click **Reject extraction**.
2. You can enter a **Rejection reason (optional)**, up to 1,000 characters.
3. Click **Reject extraction**.

Matcher discards the candidates. Nothing enters the source. The review status changes to **Rejected**. If you entered a reason, the review page shows it.

> [!TIP]
>
> If another person decides on the review first, the screen reloads the review and shows its new status.
