# Bank Statements

OpenFinance extracts transactions from bank statement PDFs using AI. Upload a PDF, and the system automatically identifies transactions, amounts, dates, and balances.

## How It Works

<Steps>
  <Step title="Upload a PDF">
    Navigate to **Statements** and click **Upload Statement**. Select one or more bank statement PDF files.
  </Step>

  <Step title="AI processes the statement">
    The system converts PDF pages to images, extracts text, and sends both to the configured AI model via OpenRouter. The AI identifies:

    * Bank name and account number
    * Statement period (start and end dates)
    * Opening and closing balances
    * All individual transactions with dates, descriptions, and amounts
  </Step>

  <Step title="Balance verification">
    After extracting transactions, the system calculates whether the sum of transactions matches the stated opening and closing balances. If there is a discrepancy, the AI retries extraction (up to 15 attempts) to improve accuracy.
  </Step>

  <Step title="Transactions are saved">
    Once verified, all transactions are saved to the database and automatically linked to the correct bank account. If the account does not exist yet, it is created.
  </Step>
</Steps>

## Supported Banks

OpenFinance works with any bank that provides PDF statements. The AI model adapts to different statement formats. Commonly used with:

* Canadian banks (TD, RBC, BMO, Scotiabank, CIBC)
* US banks (Chase, Bank of America, Wells Fargo)
* Credit unions and online banks

## Statement Details

After processing, each statement shows:

| Field               | Description                                          |
| ------------------- | ---------------------------------------------------- |
| Bank Name           | Automatically detected from the PDF                  |
| Account Number      | Extracted account identifier                         |
| Period              | Start and end date of the statement                  |
| Opening Balance     | Balance at the start of the period                   |
| Closing Balance     | Balance at the end of the period                     |
| Verification Status | Whether the extracted transactions balance correctly |
| Transaction Count   | Number of transactions extracted                     |

## Duplicate Detection

OpenFinance computes a content hash for each uploaded PDF. If you upload the same file twice, the system detects it as a duplicate and warns you.

## Tips

* Upload statements in chronological order for the best experience with balance tracking
* Statements work best when they are unmodified PDFs from your bank (not scanned paper copies)
* After processing, review the transactions and correct any categorization errors -- the AI learns from your data patterns over time
