Blackboard Ally vs Manual Remediation — Which Is Better?
Ally scans, scores, and now offers basic PDF fixes and AI alt text — but deep structural remediation is still on you. Manual remediation produces fully compliant files but doesn't scale. Here's how to combine both effectively.
Updated March 22, 2026
Neither approach alone is sufficient. Blackboard Ally excels at identifying accessibility issues across your LMS and generating alternative formats for students, but it does not actually fix your documents. Manual remediation produces fully compliant files, but it does not scale when a department has thousands of PDFs, slide decks, and Word documents to address. The most effective strategy combines both: Ally for monitoring and triage, and targeted remediation — manual or AI-assisted — for the documents that need structural repair.
This post breaks down what each approach actually does, where each falls short, and how to build a practical workflow that satisfies both WCAG 2.1 requirements and your faculty's limited time.
What Blackboard Ally Actually Does
There is a common misconception that Ally "fixes" your course content. It does not. Ally is a scanning and alternative-format tool that integrates directly into Blackboard Learn. Here is what it provides:
As of 2026, Ally has added AI alt text generation (Microsoft-powered) and PDF Quick Fixes for basic metadata (title, language, OCR). These are useful additions — but they don't constitute full remediation. Table structure, heading hierarchy, reading order, and LaTeX remain untouched.
- Accessibility scoring — Every file uploaded to your course receives a colored indicator (red, orange, yellow, green) based on automated checks for issues like missing alt text, poor heading structure, low contrast, and missing document language.
- Alternative formats — Ally automatically generates alternative versions of uploaded files, including tagged PDF, HTML, ePub, electronic braille, and audio. Students can download these from within the LMS without contacting the instructor.
- Institutional reporting — Administrators get a dashboard showing accessibility scores across departments, courses, and file types, which is valuable for compliance tracking and resource allocation.
- Instructor guidance — When an instructor clicks on a low score, Ally provides step-by-step suggestions for improving the original file.
These are genuinely useful capabilities. For institutions that have no accessibility monitoring at all, Ally represents a significant improvement. The institutional dashboard alone can help leadership understand the scale of the problem.
What Ally Does Not Do
Understanding Ally's boundaries is critical for compliance planning.
Ally does not modify your original files. The PDF you uploaded with missing tags, no reading order, and absent alt text remains exactly as it was. Ally's alternative formats are machine-generated conversions that work reasonably well for simple documents but struggle with complex layouts, tables, mathematical notation, and multi-column designs.
Ally's WCAG coverage is limited. It checks for a subset of WCAG 2.1 success criteria — primarily those that can be detected through automated scanning. It does not evaluate whether your alt text is actually meaningful, whether your reading order makes semantic sense, or whether your data tables have properly associated headers. These are the differences between scanning and remediation that matter most for compliance.
Ally does not check inline LMS content. If you build content directly in Blackboard's text editor — announcements, assignment descriptions, discussion prompts — Ally's file-level scanning does not cover it. Inline content accessibility depends entirely on the instructor's authoring practices.
Alternative formats have quality limits. An auto-generated tagged PDF from a scanned image-based document will not be usable. A complex table converted to HTML may lose its logical structure. Students who rely on these alternative formats are sometimes receiving content that is technically "alternative" but not functionally accessible.
What Manual Remediation Involves
Manual remediation means a trained person opens the original document and repairs it to meet WCAG 2.1 standards. For a PDF, this typically includes:
- Adding or correcting the tag structure (headings, paragraphs, lists, tables)
- Setting a logical reading order
- Writing meaningful alt text for every image
- Associating table headers with data cells
- Setting the document language
- Ensuring proper bookmarks and navigation
- Running OCR on scanned pages before tagging
For a thorough overview of what PDF remediation requires, the scope grows quickly with document complexity. A simple ten-page syllabus might take 30 minutes. A 200-page course pack with tables, figures, and footnotes can take a full working day.
Manual remediation produces the highest-quality output. A skilled remediator makes judgment calls that no automated tool currently handles well — deciding whether a decorative image needs alt text or an empty tag, restructuring a poorly designed table so it makes sense when linearized, or splitting a visual layout into a logical reading sequence.
Manual remediation does not scale. A mid-sized department might have 5,000 documents across active courses. At an average remediation vendor rate of $30–80 per document, full manual remediation of a department's content library could cost $150,000–400,000 — before accounting for new content uploaded each semester.
When Manual Remediation Is Necessary
Certain documents justify the investment in manual (or expert-assisted) remediation:
- High-use documents — A syllabus accessed by 500 students per semester deserves proper tagging.
- Complex layouts — Research papers, lab manuals, and course packs with tables, figures, and multi-column formatting rarely survive automated conversion intact.
- Legal exposure — Documents associated with accommodation requests or complaint processes should meet full WCAG 2.1 AA.
- Permanent resources — Materials reused across multiple semesters have a longer return on the remediation investment.
For a low-stakes, single-use handout, Ally's alternative formats may be perfectly adequate. For your department's core curriculum documents, they probably are not.
The Hybrid Approach
The practical path for most institutions looks like this:
- Use Ally for visibility. Let its institutional dashboard show you where the problems are, which departments have the lowest scores, and which file types are most common offenders.
- Triage by impact. Prioritize remediation for high-enrollment courses, frequently accessed documents, and content types that Ally's alternative formats handle poorly (complex PDFs, spreadsheets with data tables, scanned documents).
- Remediate strategically. Address the highest-priority documents with proper remediation — whether manual, AI-assisted, or a combination — and accept Ally's alternative formats as a stopgap for lower-priority content.
- Train faculty on authoring. The most cost-effective long-term strategy is teaching instructors to create accessible documents from the start. An accessible Word document uploaded to Blackboard will score green in Ally and need no remediation at all.
- Reassess each semester. As old content is retired and new content is created with better authoring practices, the remediation backlog shrinks over time.
Cost Comparison
The cost gap between scanning-only tools and full manual remediation is exactly where AI-assisted remediation has emerged. Tools that can automatically tag PDFs, generate contextual alt text, and repair reading order bring per-document costs closer to Ally's range while producing output closer to manual quality.
- Ally (institutional license): ~$2–5 per student/year — scales well, basic PDF fixes (title, language, OCR) + AI alt text added in 2026, but no structural remediation; partial WCAG coverage
- Manual remediation vendor: $30–80 per document — does not scale, fixes originals, full WCAG coverage
- AI-assisted remediation: $1–10 per document — scales well, fixes originals, near-full WCAG coverage
- Faculty authoring training: One-time investment — scales well, prevention-focused, coverage depends on adoption
Making the Decision
If your institution already has Blackboard Ally, keep using it. Its monitoring and alternative-format capabilities fill a real need, and your Blackboard courses benefit from its integration. But do not treat Ally scores as proof of compliance. A green score means Ally's automated checks passed — not that a screen reader user will have a good experience with your document.
For the documents that matter most, invest in actual remediation. Whether that is a manual vendor, an in-house specialist, or an AI-assisted platform like Aelira that can process your document backlog at scale, the goal is the same: original files that are genuinely accessible, not just scored.
The DOJ's ADA Title II deadline does not distinguish between "we had a scanning tool" and "we fixed our documents." Your compliance strategy should not either.
