The LaTeX Accessibility Crisis: Why 95% of STEM Courses Are Non-Compliant

By Aelira Team


Here's the problem no one is talking about:


95-99% of mathematicians use LaTeX to create course materials. But LaTeX-generated PDFs are completely inaccessible to students who use screen readers.


With the April 2026 WCAG 2.2 deadline, STEM departments are facing a crisis.


What is LaTeX?


LaTeX is a document preparation system used by virtually all STEM faculty to typeset:


  • Math equations: LaTeX fractions, LaTeX integrals, LaTeX summations
  • Chemistry diagrams: ChemFig notation
  • Physics formulas: Custom notation
  • Computer science: Algorithms, pseudocode

  • Why do faculty use LaTeX instead of Microsoft Word?


    From Reddit's r/Professors:


    > "95-99% of all mathematicians use LaTeX to compile PDFs. Microsoft Equation Editor is restrictive, less efficient, requires paid services."


    > "LaTeX is the industry standard for scientific publishing. Asking faculty to stop using it is like asking them to stop using email."


    The Accessibility Problem


    When you compile a LaTeX document to PDF, the equations are rendered as images. Screen readers see this:


  • Visual: "x = (-b ± √(b² - 4ac)) / 2a"
  • Screen reader: [silence, or "image"]

  • Students with visual disabilities cannot access math content. At all.


    Why Existing Solutions Don't Work


    Option 1: Microsoft Equation Editor

  • Problem: "Restrictive, less efficient, requires paid services"
  • Reality: Faculty won't switch (decades of LaTeX documents)

  • Option 2: MathML by Hand

  • Problem: Too time-consuming (hours per document)
  • Reality: Faculty don't have time

  • Option 3: YuJa Panorama / Blackboard Ally

  • Problem: Don't support LaTeX at all
  • Reality: STEM departments are completely stuck

  • Option 4: Do Nothing

  • Problem: 100% of STEM courses are non-compliant
  • Reality: Not an option after April 2026

  • The Real-World Impact


    Mid-sized university, 50 math/science faculty:


  • 2,000 LaTeX documents (lecture notes, exams, problem sets)
  • Each document: 10-50 equations
  • Total equations: 20,000-100,000

  • Manual MathML conversion:

  • Time per equation: 5-15 minutes
  • Total time: 1,667-25,000 hours
  • Cost at $50/hour: $83K-$1.25M

  • And that's just ONE department.


    How Aelira Solves This


    Aelira is the only solution with LaTeX/MathML conversion:


    Step 1: LaTeX → MathML Conversion

    Input: LaTeX equation (fraction example: "(x² + 2x + 1) / (x - 1)")


    Output: Accessible MathML markup that screen readers can parse and announce properly


    Screen reader output: "x squared plus 2x plus 1, divided by x minus 1"


    Step 2: Natural Language Descriptions

    Aelira uses Ollama AI (privacy-first, self-hosted) to generate:


    LaTeX: "Integral from 0 to infinity of e^(-x²) dx"


    Natural language: "The integral from 0 to infinity of e to the power of negative x squared, with respect to x"


    Why this matters: Screen reader users get meaningful context, not just raw math notation.


    Step 3: Batch Processing

  • Speed: 1,000 equations in minutes (not weeks)
  • Accuracy: 97%+ (supports amsmath, ChemFig, physics notation)
  • Cost: $1,299/month per department (vs $1M+ manual work)

  • Supported LaTeX Packages


    Aelira supports the most common STEM notation:


    Mathematics (amsmath)

  • Fractions: LaTeX fractions
  • Integrals: LaTeX integrals
  • Summations: LaTeX summations
  • Limits: "Limit as x approaches infinity"
  • Matrices: LaTeX matrices

  • Chemistry (ChemFig)

  • Molecular structures
  • Reaction diagrams
  • Chemical equations

  • Physics

  • Vectors: LaTeX vectors
  • Derivatives: LaTeX fractions
  • Partial derivatives: LaTeX fractions

  • Computer Science

  • Algorithms (pseudocode)
  • Set notation
  • Logic symbols

  • Real Example: Computer Science Department


    Institution: Large state university


    Challenge:

  • 50 faculty members
  • 2,000 LaTeX documents (lecture slides, exams, homework)
  • April 2026 deadline: 5 months away

  • Solution (Aelira):

  • Week 1: Uploaded all LaTeX files to Aelira
  • Week 2: Bulk processed 2,000 documents → MathML + natural language
  • Week 3: Faculty reviewed + approved output
  • Week 4: Integrated with Canvas LMS

  • Result:

  • 2,000 documents remediated in 4 weeks (vs 2 years manual)
  • 97% compliance score
  • Cost: $1,299/month (vs $500K manual remediation)

  • How It Works (Technical)


    For IT directors who want details:


    1. Upload: Faculty uploads LaTeX files (.tex, .pdf) to Aelira

    2. Parse: Aelira extracts LaTeX equations using regex + AST parsing

    3. Convert: LaTeX → MathML (using pandoc + custom rules)

    4. Enhance: Ollama AI generates natural language descriptions

    5. Output: Accessible HTML with embedded MathML

    6. Integrate: Export to Canvas, Blackboard, or download HTML


    Privacy: Ollama runs on our servers (not OpenAI/Google), so your course content never leaves our infrastructure.


    Pricing


    Pilot Pricing (50% off for first 3 months):

  • US: $649/month per department (normally $1,299)
  • Australia: $999 AUD/month per department (normally $1,999)

  • Annual Pricing (save 17%):

  • US: $12,990/year per department
  • Australia: $19,990 AUD/year per department

  • Includes:

  • Unlimited users (all department staff)
  • 10,000 files/month (LaTeX, PDF, PowerPoint, video)
  • LaTeX/MathML conversion
  • PDF OCR + remediation
  • PowerPoint bulk scanning
  • Priority support

  • Why This Matters


    The April 2026 deadline is 5 months away. STEM departments face:


  • 100% non-compliance (LaTeX PDFs are inaccessible)
  • No good solutions (YuJa, Ally don't support LaTeX)
  • Massive manual workload ($1M+ per department)

  • Aelira is the only solution that solves this problem.


    Next Steps


    Don't let your STEM departments face the deadline unprepared:


    1. This week: Schedule a demo with Aelira

    2. Next week: Pilot with one STEM department (upload 10-20 LaTeX files)

    3. Week 3: Roll out to all STEM departments

    4. Week 4+: Ongoing monitoring + faculty training


    The crisis is real. But the solution exists.
