Inside HoloRemedi
Compliance score
A live score for the open file, updated as issues are fixed.
Issue list
Every problem grouped by rule and searchable, from alt text quality to metadata.
Live preview
The page renders beside the fixer, so each change is seen in context.
Alt text review
AI-drafted descriptions are reviewed and edited before they are written to the source.
Everything in one platform
Automated repair
Global auto-fix resolves entire categories of accessibility violations in seconds, from semantic tagging to metadata, by rule, so the same problem is fixed the same way every time.
AI-drafted alt text
AI is used for one job: drafting a description for each image that needs one. You review and edit every description before it is written to the book.
Live document preview
See every fix in context. HoloRemedi renders your EPUB alongside the remediation panel, so nothing is fixed blindly.
EPUB validation
Built-in epubcheck validates your EPUB against the specification before you export clean, distribution-ready files.
Multi-standard compliance
WCAG 2.2 AA, Section 508, EPUB Accessibility 1.1, and EAA, all tracked in a single compliance score per document.
Structural tag editor
View and edit the full tag tree, including heading hierarchy, figure tags, and ARIA landmarks, with instant visual feedback.
Clear about your data
Audit and repair run on our own infrastructure. Only images that need a description, with a short piece of nearby text, are sent to Azure OpenAI. Your content is never used to train AI models.
Audit and report export
Publisher-grade compliance reports for distributors, libraries, and regulators, with full issue traceability.
Every standard covered
HoloRemedi tracks compliance against every major accessibility standard in publishing, so your documents are ready for any market, platform, or regulator.

Two remediation tracks
Track 1: EPUB (available now)
EPUB remediation pipeline
Prepares your EPUB for EPUB Accessibility 1.1, EAA, and DAISY compliance. Structure and metadata are repaired by rule; AI drafts the alt text, and you review it before it is written.
- Semantic reconstruction with ARIA roles and landmarks
- AI-drafted alt text, reviewed before it is written
- EPUB 2 to EPUB 3.3 upgrade
- Official DAISY Ace (HTML) certification report
Track 2: PDF (coming soon)
AxiomRust engine
In development: deep binary repair for PDFs that fail PAC 2026 and VeraPDF validation. It will rebuild corrupted ToUnicode tables, resolve content-stream state leaks, and deliver PDF/UA-1 files.
- Binary font healing (ToUnicode repair)
- Content stream repair for nesting and state-leak errors
- PAC 2026 and VeraPDF (XML) compliance reports
- PDF/UA-1 certified output
The engine behind our accessibility services
When you commission EPUB remediation from Holograph Press Works, HoloRemedi runs the full pipeline: audit, automated repair, AI-drafted alt text, validation, and certification report.
Every EPUB is delivered with the legal evidence of compliance: an official DAISY Ace report. Need PDFs fixed today? Our team remediates them by hand, with PAC 2026 and VeraPDF reports. It is not a third-party tool. We built it and we own it.
