Generate Formula MathML (OpenAI)

Transform inaccessible mathematical formulas in PDFs into screen reader-compatible MathML automatically with AI.

PDFix now integrates with OpenAI Vision to automatically convert mathematical formulas into accessible MathML (Mathematical Markup Language) format. This AI-powered solution delivers PDF/UA compliance for STEM documents, ensuring that mathematical expressions are not just visible images but structured, navigable content for assistive technologies.

Meet PDFix Desktop + OpenAI: AI-Powered MathML Generation

• Advanced Recognition: AI Vision can analyze handwritten equations, printed formulas, and LaTeX expressions
• Automated MathML Generation: Converts formula images into MathML
• PDF/UA Compliance: Embeds MathML as associated files to Formula tags
• Screen Reader Compatible: Enables assistive technologies to read mathematical expressions
• Batch Processing: Process entire folders of technical documents with identical workflows

Why MathML Matters for Accessibility

MathML was specifically created by the World Wide Web Consortium (W3C) as a universally designed format for mathematical expressions, and it is supported by many assistive technology applications such as screen readers. MathML allows equations to be stored as structured text that can be reformatted, searched, and most importantly, enables blind users to navigate through mathematical expressions interactively.

How to Get Started with OpenAI

🐳 Don’t Forget to Install Docker Desktop First!

• Some PDFix external actions connect to OpenAI (for example, to analyze or summarize document content).
• To use these features, you’ll need your own OpenAI API key — it’s quick and free to set up.

Here’s how to:

1. Go to OpenAI’s Website
   • Visit https://platform.openai.com/
2. Create or Sign In to Your OpenAI Account
   • If you already have an OpenAI or ChatGPT account, just sign in.
   • If not, click Sign up and follow the short registration process. You can use your email, Google, or Microsoft account.
3. Open the API Keys Page
   • Once signed in, go directly to: https://platform.openai.com/api-keys
4. Create a New Secret Key
   • Click the “+ Create new secret key” button.
5. Use the Key in PDFix
   • Open PDFix and enter your API key in the external action settings for OpenAI.
   • PDFix will use it securely to connect to OpenAI’s servers and process your requests.

💡 Tip: Keep your API key private – don’t share it or post it online. You can always delete and generate a new one if needed.
