Laravel OCR & Document Intelligence

Turn any image or PDF into structured, actionable data.

A powerful, developer-friendly Laravel package that reads text from images and PDFs, understands the content, fixes scanning errors with AI, and delivers clean, structured data directly to your application.

Why this package? Most OCR tools just give you a dump of raw text. This package gives you typed DTOs, structured fields, and confidence scores. It knows the difference between an Invoice Number and a Phone Number.

📖 Usage

1. Simple Text Extraction

The LaravelOcr facade provides a simple entry point via the OCRManager.

use Mayaram\LaravelOcr\Facades\LaravelOcr;

// Extract from a local file path
$result = LaravelOcr::extract('/path/to/document.png');
echo $result['text'];
// "INVOICE #1001..."

// Extract from an UploadedFile
$result = LaravelOcr::extract(request()->file('document'));

// Extract a table
$tableResult = LaravelOcr::extractTable('/path/to/invoice.png');
foreach ($tableResult['table'] as $row) {
    echo implode(' | ', $row) . "\n";
}

2. Smart Parsing (Structured Data via OcrResult DTO)

For powerful data extraction, use the DocumentParser. It returns a typed OcrResult DTO with text, confidence, bounds, and metadata properties.

use Mayaram\LaravelOcr\DTOs\OcrResult;

/** @var \Mayaram\LaravelOcr\Services\DocumentParser $parser */
$parser = app('laravel-ocr.parser');

$result = $parser->parse('storage/invoices/inv-2024.pdf', [
    'document_type' => 'invoice',
    'use_ai_cleanup' => true,
    'save_to_database' => true,
]);

// Access the OcrResult DTO properties
echo $result->text;                                  // Full extracted text
echo $result->confidence;                            // e.g., 0.98
echo $result->metadata['processing_time'];           // e.g., 1.2
echo $result->metadata['document_type'];             // "invoice"
echo $result->metadata['ai_cleanup_used'];           // true

// Access structured fields
$fields = $result->metadata['fields'];
$invoiceNumber = $fields['invoice_number']['value'];
$totalAmount = $fields['totals']['total']['amount'];

3. Batch Processing

Process multiple documents at once:

$parser = app('laravel-ocr.parser');

$results = $parser->parseBatch([
    'storage/invoices/inv-001.pdf',
    'storage/invoices/inv-002.pdf',
    'storage/invoices/inv-003.pdf',
], ['document_type' => 'invoice']);

foreach ($results as $result) {
    echo $result->text . "\n---\n";
}

4. Working with Line Items & Tables

The package includes an Advanced Invoice Extractor capable of parsing complex invoice tables into structured arrays.

$result = $parser->parse($invoicePath, [
    'document_type' => 'invoice',
]);

// Line items are extracted automatically for invoices
$lineItems = $result->metadata['fields']['line_items'] ?? [];

foreach ($lineItems as $item) {
    echo "{$item['description']}: {$item['quantity']} x \${$item['unit_price']} = \${$item['total']}\n";
}
// Output:
// Web Hosting: 12 x $10.00 = $120.00
// Domain Name: 1 x $15.00 = $15.00

// Invoice totals
$totals = $result->metadata['fields']['totals'] ?? [];
echo "Subtotal: " . ($totals['subtotal']['formatted'] ?? 'N/A');
echo "Tax: " . ($totals['tax']['formatted'] ?? 'N/A');
echo "Total: " . ($totals['total']['formatted'] ?? 'N/A');

5. Templates

Define reusable templates to target specific fields using regex patterns. Templates are stored in the database and support import/export.

use Mayaram\LaravelOcr\Facades\LaravelOcr;

// 1. Create a Template
$templateManager = app('laravel-ocr.templates');

$template = $templateManager->create([
    'name' => 'TechCorp Invoice',
    'type' => 'invoice',
    'description' => 'Template for TechCorp invoices',
    'fields' => [
        [
            'key' => 'order_id',
            'label' => 'Order ID',
            'pattern' => '/Order\s*ID:\s*([A-F0-9]+)/i',
            'type' => 'string',
            'validators' => ['required' => true],
        ],
        [
            'key' => 'total_amount',
            'label' => 'Total Amount',
            'pattern' => '/Total:\s*\$?([\d,]+\.?\d*)/i',
            'type' => 'currency',
        ],
    ],
]);

// 2. Apply a template during extraction
$result = LaravelOcr::extractWithTemplate($file, $template->id);

// 3. Auto-detect template based on content
$parser = app('laravel-ocr.parser');
$result = $parser->parse($file, ['auto_detect_template' => true]);

// 4. Export / Import templates
$json = $templateManager->exportTemplate($template->id);
$imported = $templateManager->importTemplate('/path/to/template.json');

// 5. Duplicate a template
$clone = $template->duplicate('TechCorp Invoice v2');

6. Workflows

Configure processing pipelines in config/laravel-ocr.php to standardize how different document types are handled.

// config/laravel-ocr.php
'workflows' => [
    'invoice' => [
        'options' => [
            'use_ai_cleanup' => true,
            'auto_detect_template' => true,
            'extract_tables' => true,
        ],
        'post_processors' => [
            ['class' => 'App\OCR\Processors\InvoiceProcessor'],
        ],
        'validators' => [
            ['type' => 'required_fields', 'fields' => ['invoice_number', 'total']],
        ],
    ],

    'receipt' => [
        'options' => [
            'use_ai_cleanup' => true,
            'extract_line_items' => true,
        ],
        'post_processors' => [
            ['class' => 'App\OCR\Processors\ReceiptProcessor'],
        ],
    ],
],

// Usage
$parser = app('laravel-ocr.parser');
$result = $parser->parseWithWorkflow($file, 'invoice');

7. Switching Drivers at Runtime

use Mayaram\LaravelOcr\Facades\LaravelOcr;

// Use Tesseract (default)
$result = LaravelOcr::driver('tesseract')->extract($document);

// Switch to AWS Textract for this request
$result = LaravelOcr::driver('aws_textract')->extract($document);

// Switch to Google Vision
$result = LaravelOcr::driver('google_vision')->extract($document);

8. Document Metadata Extraction

$parser = app('laravel-ocr.parser');

$metadata = $parser->extractMetadata('/path/to/document.pdf');

// Returns:
// [
//     'file_name' => 'document.pdf',
//     'file_size' => 102400,
//     'mime_type' => 'application/pdf',
//     'created_at' => '2024-01-15 10:30:00',
//     'modified_at' => '2024-01-15 10:30:00',
//     'pdf_pages' => 3,
//     'pdf_author' => 'John Doe',
//     'pdf_title' => 'Q4 Invoice',
//     'pdf_creator' => 'Microsoft Word',
// ]

9. Working with Processed Documents

use Mayaram\LaravelOcr\Models\ProcessedDocument;

// Query processed documents
$documents = ProcessedDocument::where('document_type', 'invoice')
    ->where('confidence_score', '>=', 0.7)
    ->latest()
    ->get();

foreach ($documents as $doc) {
    // Get a specific field value
    $invoiceNo = $doc->getFieldValue('invoice_number');

    // Get all field values as a flat array
    $allFields = $doc->getAllFieldValues();

    // Check if the result is valid (status=completed & confidence >= 0.7)
    if ($doc->isValid()) {
        // Process the document
    }
}

🖥️ Artisan Commands

ocr_template_fields

ocr_processed_documents

🧩 OCR Driver Interface

All drivers implement the Mayaram\LaravelOcr\Contracts\OCRDriver interface:

interface OCRDriver
{
    public function extract($document, array $options = []): array;
    public function extractTable($document, array $options = []): array;
    public function extractBarcode($document, array $options = []): array;
    public function extractQRCode($document, array $options = []): array;
    public function getSupportedLanguages(): array;
    public function getSupportedFormats(): array;
}

Supported Formats by Driver

Building a Custom Driver

use Mayaram\LaravelOcr\Contracts\OCRDriver;

class MyCustomDriver implements OCRDriver
{
    public function extract($document, array $options = []): array
    {
        // Your implementation
        return [
            'text' => 'extracted text',
            'confidence' => 0.95,
            'bounds' => [],
            'metadata' => ['engine' => 'custom'],
        ];
    }

    public function extractTable($document, array $options = []): array { /* ... */ }
    public function extractBarcode($document, array $options = []): array { /* ... */ }
    public function extractQRCode($document, array $options = []): array { /* ... */ }
    public function getSupportedLanguages(): array { return ['en' => 'English']; }
    public function getSupportedFormats(): array { return ['jpg', 'png', 'pdf']; }
}

🤖 AI Cleanup Details

The AICleanupService provides two modes:

Basic Rules (No API Required)

Set provider to basic to use built-in typo correction and field normalization without any AI provider:

$result = $parser->parse($document, [
    'use_ai_cleanup' => true,
    'provider' => 'basic',
]);

Built-in corrections:

• Common OCR typos: invOice → invoice, arnount → amount, nurnber → number, custorner → customer, payrnent → payment
• OCR pattern fixes: rn → m, O before numbers → 0, l before numbers → 1
• Field normalization by type: numeric, date (→ Y-m-d), currency, email, phone

AI-Powered Cleanup (via Laravel AI SDK)

Uses the CleanupAgent with your configured LLM provider for intelligent correction:

$result = $parser->parse($document, [
    'use_ai_cleanup' => true,
    // Uses LARAVEL_OCR_AI_PROVIDER from config
]);

The agent is instructed to:

1. Fix typos and OCR errors contextually
2. Standardize formats (dates to YYYY-MM-DD, currency to decimal)
3. Preserve values it can't confidently fix
4. Return valid JSON matching the input structure

Custom Prompt

You can pass additional instructions to the AI cleanup agent to customize its behavior:

// Per-call custom prompt
$result = $parser->parse($document, [
    'use_ai_cleanup' => true,
    'custom_prompt' => 'Extract all amounts in INR. Normalize phone numbers to +91 format.',
]);

Or set a default custom prompt in config/laravel-ocr.php:

'ai_cleanup' => [
    'custom_prompt' => 'Always extract Hindi text. Format dates as DD/MM/YYYY.',
],

The custom prompt is appended as "Additional Instructions" to the default cleanup prompt, so the base OCR correction behavior is always preserved.

🧪 Testing

The package uses Pest for testing with three test suites:

# Run all tests
composer test

# Or directly with Pest
./vendor/bin/pest

# Run specific suite
./vendor/bin/pest --testsuite=Unit
./vendor/bin/pest --testsuite=Feature
./vendor/bin/pest --testsuite=Integration

Tests use SQLite in-memory database automatically via phpunit.xml configuration.
