Automated OCR Workflows

Our OCR engine has been continually improved over 15+ years and leverages AI, document layout analysis, and NLP technologies to accurately identify text in documents.

Convert 100+ File Types

Convert 100+ document types to PDF and unlock data with an OCR engine powered by heuristics, mathematics, and AI.

High-Quality Compression

Compress PDF files with an industry-leading compression engine that uses adaptive document learning and compression algorithms to significantly reduce the size of your files.

Split and Merge

Automatically merge or separate documents based on the number of pages, barcodes, or scripted rules. Extract and organize data quickly.

Smart Redaction

Permanently redact and remove sensitive information like emails, names, or phone numbers in your documents. Leveraging advanced artificial intelligence (AI) and a document understanding engine, you can automatically recognize sensitive information in a document and mark it for redaction.

Key-Value Pair Extraction

Automatically detect and extract key-value pairs from unstructured documents or images. Leveraging AI, ML, and adaptive layout understanding, you can automatically label and extract information such as phone numbers, IBANs, credit cards, names, and email addresses.

Archiving and PDF/A Support

Convert PDFs into long-term veraPDF- and ISO-compliant documents. Complies with three of the ISO standards (PDF/A-1, PDF/A-2, PDF/A-3) and works with “born digital” documents like MS Word, TIFF, and PDF files.

Barcode Recognition

Detect barcodes in TIFF and PDF files to enable document separation and/or addition of metadata. Split and rename files by barcodes. Make use of various reading options for barcode types. Specify the page where you want to start or end recognizing a barcode.

Integration with Azure and SharePoint

Azure and SharePoint are supported as a document target destination (Azure/SharePoint/Office 365 upload) and as a source (Azure/SharePoint/Office 365 download). This allows Azure/SharePoint document libraries to be populated directly from Autobahn DX jobs.

Additional Capabilities

Autobahn DX supports ultra-high performance for up to 64 cores.
Scheduled features can automatically pick up and process your files, giving you the chance to get on with your job while we do the rest.
We give you a simple user interface to run your jobs, and the Job Designer allows you to create custom jobs from a range of premade steps.
Use the Autobahn .NET API to create custom scripts that can be used within Autobahn.

Tech Spec

Extended OCR Module

The Extended OCR Module for Autobahn DX adds the IRIS OCR engine as an alternative to the standard Aquaforest engine. This has a number of benefits including optional support for Asian languages and DOCX output.

Multi-Core Licenses

The number of cores licensed determines how many CPU cores the software can use concurrently. As a rough guide, the software can process 1,000 pages per hour per CPU core although this will vary according to a number of factors.

A single Autobahn DX job can be configured to use multiple cores, processing multiple files in parallel. This is ideally suited for maximizing throughput when processing large volumes of documents of any size.

The Autobahn DX multi-core capabilities dramatically increase throughput of OCR-based jobs which are highly CPU-intensive.

Performance and Configuration

Our team is able to offer advice on the best product configuration and hardware to achieve your performance goals. Just let us know what your throughput requirements are and we will help – email
