FAQ
What is Zero-Shot Classification?
Zero-Shot Classification means our LLMs can classify documents instantly – without training, without sample data, without templates. Simply describe your desired categories in natural language, and the AI understands and sorts. This fundamentally differentiates PaperOffice from all rule-based or ML-trained systems that require weeks or months of preparation.
Does Classification cost extra or is it included in AI-DMS?
Classification is fully included in AI-DMS – at no extra cost! Every document processed through AI-DMS is automatically classified: document type, direction, locale, publisher, entities, and workflow state. For developers who only want to use the Classification API standalone, there is an affordable API access option.
How does publisher and logo detection work?
PaperOffice uses a two-stage system: First, the AI extracts logos from documents and creates 2048-dimensional vectors via Qwen3-VL. These are matched via cosine similarity against the Publisher Registry (threshold: 85%). Second, the publisher name is extracted from the document content and normalized. Detected publishers can automatically trigger workflows.
What document types are recognized?
PaperOffice recognizes 479+ predefined document categories, including: invoices, contracts, delivery notes, reminders, bank statements, medical letters, prescriptions, applications, tax assessments, customs documents, and many more. Additionally, you can define unlimited custom categories in natural language – without training.
Can I define custom categories?
Yes, unlimited! Simply describe your categories in natural language, e.g., 'All documents containing a damage report for vehicle accidents'. The LLMs understand the description and classify accordingly from that moment. Hierarchical structures like Accounting → Incoming Invoices → Telecommunications are also supported.
How accurate is the classification?
100% Accuracy. Our specialized LLMs recognize at least what an experienced clerk would recognize – often more. The combination of 479+ predefined categories, context-based understanding, and hierarchical classification delivers consistent results. Every classification includes a confidence score.
How many languages does Classification support?
139 languages are supported. The LLMs recognize document types language-independently – a German invoice is classified just as reliably as a Japanese invoice or an Arabic contract. Locale detection automatically identifies the document language.
Is there an API for developers?
Yes! The Classification API is RESTful with OAuth 2.0, OpenAPI 3.0 specification, and SDKs for Python, Node.js, Java, and more. Webhook support for asynchronous processing is included. The Postman Collection enables getting started in under 5 minutes. Response time: average under 100ms at 100% uptime SLA.
What differentiates PaperOffice from rule-based classification?
Rule-based systems require hundreds of manually maintained rules, break down with unknown document types, and have no context understanding. PaperOffice uses specialized LLMs that understand documents like a human: content, layout, context, and even visual elements like logos. Zero-Shot means: ready immediately, no rule maintenance, no upkeep.
Is Classification GDPR compliant?
Yes, fully. All data is processed in our own EU data centers – no AWS, no Azure, no US cloud. AES-256 encryption at rest and in transit, RAM disk processing leaving no traces, complete audit trail, and SOC 2 Type II certification. Additionally HIPAA-ready for healthcare data.
