## Continual Engine (CE)

Continual Engine builds AI tooling for a very specific hard problem: making large volumes of digital content accessible without a proportional increase in cost or turnaround time. Its PREP Remediation Suite handles PDFs, Word documents and scanned pages, tagging structure, tables and reading order so files pass WCAG and Section 508 checks. PREP Smart HTML converts PDFs into accessible HTML, while a family of APIs (Accessibility Checker, Auto Tag, PDF Audit) lets teams validate and remediate at scale inside their existing pipelines and CMS or LMS integrations.

The company's Invicta engine specialises in alt text at scale, generating consistent image descriptions across technical disciplines, and its video services cover closed captions, transcripts and extended audio descriptions. ContinuA11Y addresses websites with an accessibility plugin, a colour contrast checker and an audit API for hosted PDFs. Complementary professional services cover PPT accessibility, courseware, VPAT/ACR documentation and ADA Title II work.

Positioning is enterprise and compliance-led: CE markets cost savings of up to 80% and time-to-market reductions of up to 85%, and states ISO, SOC 2 and GDPR alignment. Customers are municipalities, universities, publishers and regulated industries, and pricing is quoted per engagement rather than published as a flat rate.

**Pricing & Plans:** Contact for pricing. Continual Engine does not publish list prices; plans are quoted per engagement based on document volume, service mix (SaaS, API, managed service) and support level. A demo is the usual entry point.

- **PREP Remediation Suite:** Automated remediation for PDFs, Word files and scanned pages, including complex tables, with CMS and LMS integrations and a Canvas LTI app.
- **Invicta Alt-Text API:** Generates consistent, high-quality image descriptions across mathematics, science, engineering and other specialist subjects at publishing scale.
- **Video Accessibility:** Closed captions, transcripts and extended audio descriptions for video and audio content, produced with automated plus human review workflows.
- **Website Accessibility:** ContinuA11Y plugin, colour contrast checker and an audit API for hosted PDFs to find and fix website barriers.
- **Compliance Services:** Specialist services for PPT accessibility, courseware, VPAT/ACR documentation and ADA Title II obligations, backed by human quality assurance.

**Strengths:** Automates painful, high-volume remediation work such as scanned PDFs and complex tables; Covers documents, images, video and websites under one vendor relationship; APIs and CMS/LMS integrations support compliance at enterprise scale; Human review layers on top of AI output, which matters for legal and academic accuracy

**Limitations:** No transparent public pricing, so budgeting requires a sales conversation; Enterprise-oriented setup may be heavier than a small team needs; Deliverable quality and timelines depend on engagement scope rather than self-serve tools

## Doc2X

Doc2X is a document processing platform from NoEdgeAI that focuses on one idea: a PDF should not be the end of a document, but a step on the way to something editable and reusable. You upload papers, scanned exams, teaching materials, financial reports or books, and the service recognises body text, formulas, tables, figures and code in reading order, then exports the content into the format that fits your next task.

The online workspace covers format conversion, translation and analysis. Supported exports include editable Word with reasonably faithful layout, WPS and MathType styles, Markdown, LaTeX, Typst, HTML, Excel for extracted tables and searchable PDFs for scanned archives. Translation keeps the original layout and can produce bilingual side-by-side documents, which is popular with researchers reading foreign-language papers.

Beyond conversion, Doc2X adds document-level AI: a multi-document knowledge base where answers cite the original pages, AI proofreading that flags typos and formula or structure issues, exam question organisation with answer matching, and slide generation from parsed PDFs. A developer open platform exposes parsing and conversion APIs (Markdown, LaTeX and DOCX exports are documented) for integrating document workflows into your own product. Pricing and quotas are shown inside the workspace and on the open platform rather than on the marketing site.

**Pricing & Plans:** Free trial available, with usage-based paid plans; quotas and plan pricing are listed inside the Doc2X workspace, while API pricing is shown on the developer open platform.

- **Layout-preserving PDF to Word:** Convert PDFs and scans into editable .docx files that keep page size, columns and image placement, with formulas editable as native Word objects.
- **Formula, table and code OCR:** Recognise math formulas into LaTeX, image tables into XLSX and document code blocks, so technical and scientific material stays usable.
- **Bilingual document translation:** Translate full documents while keeping the original layout, exporting either translation-only or side-by-side bilingual PDFs.
- **Multi-document knowledge base:** Ask questions across several uploaded documents and get answers with citations back to the source pages for verification.
- **Developer API and open platform:** Integrate parsing and conversion into your own systems via documented APIs with Markdown, LaTeX and DOCX outputs.

**Strengths:** Very broad export coverage: Word, Markdown, LaTeX, Typst, HTML, Excel, searchable PDF.; Strong formula and table recognition suited to academic and technical documents.; Translation preserves layout and supports bilingual output for careful reading.; Document-level AI features such as cited Q&A and proofreading add value beyond conversion.

**Limitations:** No publicly listed price on the main site, so costs must be checked inside the workspace or open platform.; Best results depend on document quality; scans with heavy handwriting or unusual layouts may need manual review.
