FAQ
Frequently asked questions
IDP uses AI technologies including OCR, NLP, and machine learning to automatically extract, classify, and validate data from unstructured and semi-structured documents like invoices, contracts, and forms.
Modern IDP tools typically achieve 85-99% accuracy depending on document complexity. Structured documents like invoices see higher accuracy, while handwritten or heavily formatted documents may need human review.
Yes, most modern platforms support handwriting recognition (ICR), though accuracy varies. Tools like Hyperscience and Amazon Textract offer dedicated handwriting support.
OCR simply converts images to text. IDP goes further by understanding document structure, extracting specific fields, classifying documents, and validating extracted data using AI.
Template-free tools like Rossum can be productive within days. Custom solutions may take 4-8 weeks for training and integration. Enterprise deployments typically need 2-3 months including testing.
