Vertical document body combining OCR, dictionaries, lightweight models and frontier models with human review where it belongs. No AI-vendor lock-in.

## Frequently asked questions

### What can be automated in a company's document operation?

Bulk ingestion of documents (invoices, cases, tenders), classification by type, extraction of relevant fields, routing to the correct process, semantic analysis of tenders and cases, reliable tabular extraction with dedicated OCR, and assisted drafting of internal documents with cited sources.

### Does automation replace the human team?

No. The system proposes and explains; the person with responsibility reviews, edits and signs off. When the model is not confident, the system says so instead of making it up. Human review is mandatory where legal or reputational responsibility applies.

### Which AI tools are used?

Dedicated OCR for tables and positional fields, dictionaries for catalogs and codes, lightweight API models for classification and interpretation, and frontier models only when the problem really requires it. The Semantic Scale decides the right level per task.

### How is cost controlled?

Billing is by understandable units (pages processed, documents extracted, cases analyzed) and not by generic 'AI'. Also, a frontier model is not used to classify an invoice: OCR and dictionary for the tabular part, lightweight model for the interpretive part, frontier only when it pays off.

### Does the system depend on a single AI vendor?

No. The model gateway lets us switch between OpenAI, Anthropic, Google or local models without rewriting the system. The switch happens for price, privacy, quality on the specific task, or because a provider deprecates a model.
