The intelligent document processing (IDP) market is crowded with solutions that promise automation and accuracy. Many of these platforms are powered by legacy machine learning or OCR-based technology – tools that were once cutting-edge but now struggle to keep pace with the complexity and scale of modern document workflows.
The best intelligent document processing software does more than read text on a page. It learns, adapts and improves over time. That’s where model memory comes in. It’s a next-generation approach that closes the accuracy gap, reduces manual intervention and outperforms traditional OCR and machine learning-based IDP systems.
In this article, we’ll break down the differences between legacy and modern IDP approaches, explain why intelligent document recognition has evolved beyond templates and static models, and show how Affinda’s model memory sets a new benchmark for AI document management.
Before the rise of IDP, most organizations relied on OCR (optical character recognition) tools to extract data from documents. While OCR revolutionized digitization, it was largely limited as it could read characters, but not understand context or meaning.
Early machine learning-based IDP systems improved on OCR by introducing pattern recognition and basic classification. However, these solutions were still brittle. Accuracy depended heavily on document layout consistency, requiring templates or predefined rules to function well.
This is where the OCR vs IDP debate often begins: OCR extracts text, while IDP ‘understands’ it. But many legacy IDP systems built on older machine-learning approaches never moved past the constraints of simple text extraction. The result is partial automation and constant manual corrections.
The accuracy and maintenance ceiling of machine learning IDP
Traditional machine learning-based IDP solutions may not be able to adapt to real-world document variability. While accuracy can be strong in controlled conditions, performance drops when formats, layouts or data fields change. This inconsistency, not a fixed accuracy number, is what creates the ceiling: teams still face manual reviews, exception handling and downstream rework that limit automation.
These systems struggle because they rely on static models that don’t adapt well to new document types or layout variations. Improving accuracy in traditional ML-based systems often requires significant upkeep: retraining models, maintaining feature sets, refreshing datasets and reconfiguring templates or rules. Even small layout changes can trigger this maintenance cycle, adding cost and complexity.
For enterprises investing in AI for document management, this creates a dilemma: you’re promised automation but end up with partial solutions that demand ongoing maintenance. The result is long onboarding, limited scalability, slower workflows and higher operational costs. Workflows slow down because the system isn’t fully automated, forcing teams to pause for manual checks, exception handling and model adjustments before anything can move forward.

Enter model memory: the next generation of IDP
Model memory overcomes the limitations of traditional machine learning and OCR-based IDP solutions. Instead of relying on static models or fixed templates, model memory learns from every document processed. And when a user corrects an extraction once, the system remembers it for future documents.
This approach enables true intelligent document recognition, with context-aware understanding that adapts to structure, language or formatting variations across document types. Over time, model memory compounds its learnings, driving accuracy above 99% and making straight-through processing achievable even for complex workflows.
As more vendors claim to offer AI-powered IDP, the differentiators are the ones that show continuous learning, high accuracy on real documents, fast model creation and the ability to scale without heavy maintenance. These are the capabilities that separate modern IDP platforms from legacy OCR and static ML tools.
Why model memory outperforms traditional machine learning
When evaluating the best intelligent document processing software, many organizations compare legacy vendors, such as ABBYY or OCR-first platforms, to newer AI solutions. The difference lies in how these systems learn and scale over time.
- Learning approach: Traditional machine learning models are static. Accuracy depends on training datasets and frequent manual updates. Model memory learns dynamically from every interaction with a user or document, improving results in real time without the need for retraining.
- Accuracy: Traditional ML and OCR-first IDP tools often deliver inconsistent accuracy as document layouts and fields change. Our model memory technology maintains high accuracy across variations and can push performance above 99% because it learns from every interaction.
- Flexibility: OCR and template-based systems often fail when formats change. Model memory adapts to new layouts, document types and languages without configuration headaches.
- Maintenance: Older solutions need constant model tuning and manual upkeep to stay accurate. Model memory removes most of that maintenance load, freeing teams to focus on higher-value work.
The business case for partnering with Affinda
Outdated OCR and machine learning-based IDP solutions limit true automation. Their accuracy often varies as document formats change, which drives up maintenance costs and creates ongoing exception handling for teams.
Our IDP platform with model memory changes the game. We deliver higher precision, adapt instantly to new document formats and let you set up new workflows fast – starting small and scaling smoothly after a proof of concept.
For enterprises evaluating the best intelligent document processing software, the IDP vs OCR choice comes down to intelligence. Legacy OCR extracts text but lacks context or adaptability. Model memory learns continuously, delivering precision and efficiency that traditional approaches can’t match.
