| OCR | OCR runs on scanned pages before the accessibility check. | PREP includes OCR mode to recognize scanned documents, including documents with poor quality or complex structures. |

In their own words
Normfluss
Normfluss checks PDF documents for accessibility, applies structural fixes, and provides a signed record describing the checks and decisions made. It evaluates PDFs against PDF/UA-1 and the parts of WCAG 2.2 AA that apply to PDF files. The platform can automatically handle tags, reading order, and tables; people review judgment calls in a guided editor. A self-hosted model drafts image descriptions in English, French, German, or Dutch, but a person must accept each suggestion before it is applied.
Users can check up to 25 PDFs at once for free. Files may be up to 100 MB and 150 pages without an account, or 1,000 pages with a free account. A remediated file can be downloaded with a signed evidence record. Normfluss offers a REST API and HMAC-signed webhooks. Processing takes place in the EU; the maker says models are self-hosted, files are not used for training, and no third-party AI is used. Unauthenticated free-check files are deleted after 72 hours; account documents remain until deleted. Plans include a free check and one-time credit bundles from €50, paid once. The platform reports technical conformance, not legal certification or advice.
