Author structured documents that are signed, versioned, and accessible by design.
The native OSDF editor uses a passive semantic object model - not raw HTML - so documents stay safe to open and deterministic to render. Every committed revision is canonicalized, hashed, linked to its parent, and signable.
- Passive semantic schema - no embedded code
- Hash-linked, append-only revision history
- Accessibility built into the document tree

What OSDF Editor does
Semantic model
Headings, sections, tables, forms, and reading order as first-class structure.
Revisions
Immutable committed revisions form an append-only, verifiable chain.
Scoped signatures
Sign a whole document or define immutable scopes with mutable fields.
Accessibility
Semantic headings, alt text, language tags, and keyboard-complete editing.
Declarative forms
Typed, bounded calculations with no general-purpose scripting.
PDF interop
Import PDFs into editable projects and export clean PDF/A renditions.
The future of trusted documents
Bring cryptographic verification, verifiable provenance, and zero-trust access control to every document your organization creates and receives.
