Honest comparison of accessibility tools for higher education.
Ally generates AI alt-text and applies limited source fixes. Aelira adds native LaTeX, deep tag-tree and table remediation, and on-prem AI.
Best for: Universities in the Anthology/Blackboard ecosystem who want in-LMS scoring, alternative formats, and AI alt-text
Pricing: Enterprise / quote-based (not publicly listed)
Best for: Universities that need deep, multi-type remediation including native LaTeX, with an on-prem option
Pricing: $1,499/mo per department (defined processing allowance)
| Feature | Anthology Ally | Aelira |
|---|---|---|
| AI-Generated Fixes AI produces accessible output you can apply | AI alt-text (Claude), instructor-approved | Yes Working fixes across document types |
| Native LaTeX Remediation Remediate LaTeX source to accessible MathML | Office Math → MathML (no LaTeX source) | Yes Native LaTeX source → MathML |
| Deep Source Remediation Fix tag tree, tables, and reading order in the source | Limited source fixes (title, language, OCR) | Yes Tag tree, tables, reading order |
| Bulk / API File Pipeline (1,000+ files) Scan entire departments outside the LMS | LMS-integrated (no standalone bulk API) | Yes CLI + web bulk scanning |
| LMS Integration Works inside Canvas, Blackboard, etc. | Yes Canvas, Blackboard, Moodle, D2L + Ally for Web | Yes Canvas LTI 1.3 (verified); Blackboard LTI 1.3 in beta |
| Cloud Storage Integration Connect to Google Drive, OneDrive, SharePoint | No Not supported | Yes Google + Microsoft 365 |
| On-Prem / Self-Hosted AI Keep document content on your own servers | No Cloud-only SaaS | Yes Self-hosted open-source AI |
| Pricing Transparency Know the cost before signing | No Quote-based (not public) | Yes $1,499/mo per dept |
Ally is part of the Anthology suite, which means it's tightly integrated with Blackboard Learn. Faculty can see accessibility scores directly in the LMS without switching tools.
Ally automatically generates alternative formats (HTML, ePub, audio, BeeLine Reader) from uploaded files. This provides multiple ways for students to access content.
At universities using Blackboard, faculty awareness of Ally is high (commonly reported in the majority range; approximate, from public sources). The visual accessibility score (red/yellow/green) is easy to understand at a glance.
Ally has been around since 2016 and is widely deployed across higher education. It's a known quantity with enterprise support and ongoing updates.
Ally remediates, but narrowly. Here's where Aelira goes deeper.
Ally's PDF Quick Fixes overwrite the source file for a limited set of issues (missing title, missing language, and scanned-PDF OCR), and its AI Alt-Text Assistant (Anthropic Claude) generates instructor-approved alt text. It does not rebuild the deep tag tree, table structure, or reading order.
Aelira difference: deep, multi-type source remediation across tag tree, tables, and reading order.
Ally converts Office Math (Word) to MathML, but does not support LaTeX, the format most STEM faculty author equations in. Aelira ingests native LaTeX source and produces accessible MathML with ARIA labels.
Aelira difference: native LaTeX source → MathML, not just Office Math.
Ally operates inside the LMS (and via Ally for Web), so there's no standalone bulk file or API pipeline for scanning a department's shared drive or local files. Aelira offers CLI and web bulk processing for thousands of files.
Ally is a cloud-only SaaS (documents are processed off your servers) with quote-based pricing that isn't publicly listed. Aelira offers a fully self-hosted on-prem option and publishes its pricing.
Aelira generates working HTML/CSS/JS fixes across document types that you can copy-paste or apply automatically.
Example: Missing alt text? Aelira generates contextual descriptions. Low contrast? Aelira suggests WCAG-compliant color combinations.
Aelira remediates native LaTeX source and converts it to accessible MathML with ARIA labels, the format most STEM faculty author in.
Why it matters: the overwhelming majority of mathematicians author in LaTeX. Tools that only convert Office Math don't remediate those source files.
Connect to Google Workspace, Microsoft 365, and Canvas today, with Blackboard in beta — together covering the large majority of higher-ed platforms (approximate market-share estimates from public sources). Real-time webhooks detect file changes.
Auto-remediate: Fix files and upload corrected versions back to cloud storage.
Ally and Aelira can complement each other. Use Aelira for deep source remediation (PDFs, PowerPoints, native LaTeX, tables, reading order), then let Ally provide in-LMS scoring and alternative formats for students. This gives you both deeply remediated source files and multiple access options.
Both tools remediate accessibility issues. They differ in depth, math support, deployment, and pricing.
Ally generates AI alt-text (Anthropic Claude) and applies limited source fixes (title, language, OCR). Aelira additionally rebuilds the tag tree, table structure, and reading order across document types.
Ally converts Office Math (Word) to MathML. Aelira remediates native LaTeX source, the format the overwhelming majority of STEM faculty author equations in.
Ally is a cloud-only SaaS. Aelira can run fully self-hosted on open-source AI, so document content never leaves your servers.
Ally's pricing is quote-based and not publicly listed. Aelira publishes its pricing at $1,499/mo per department.
The takeaway: Ally is strong for in-LMS scoring, alternative formats, and AI alt-text. Aelira adds deeper source remediation, native LaTeX, an on-prem option, and transparent pricing.
