The record

Product: Normfluss detects, remediates and validates accessibility issues in PDF documents and issues a signed evidence record of what was tested and fixed within a stated scope.
Automatic remediation: The platform automates structural fixes including tags, reading order and tables, while people review judgment calls in a guided editor.
Standards: It checks PDFs against PDF/UA-1 and the parts of WCAG 2.2 AA that apply to PDFs.
Evidence: Each remediated document can be downloaded with a signed record describing what was tested, what passed and who decided judgment calls.
Batch limits: Users can check up to 25 PDFs at once for free; the site allows PDFs up to 100 MB and up to 150 pages without an account or 1,000 pages with a free account.
Integrations: Normfluss offers a REST API and HMAC-signed webhooks for checking and remediating documents from a customer system or pipeline.
Image descriptions: A self-hosted model drafts image descriptions in English, French, German or Dutch, and suggestions are not applied until a person accepts them.
Data handling: Document processing takes place in the EU, models are self-hosted with no third-party AI, and files are never used for training.
Retention: Unauthenticated free-check files are deleted after 72 hours; account documents remain until the user deletes them.
Limits: Normfluss says it reports technical conformance and does not provide legal certification or legal advice.
Intended users: The product is positioned for businesses, compliance/content/operations teams, public-sector and healthcare organizations, and software platforms that generate customer documents.
Support: The maker describes Normfluss as software users run themselves and says it is not a service performed for them.
Maker: The site states that Normfluss is owned and operated by Nikola Innovations Limited.
