I built a tool that makes documents accessible, with AI agents writing most of the code

A Purdue professor built Docable, a working tool that turns PowerPoint, Word and PDF files into accessible versions for new disability rules. The AI and the AI helped him create a codebase of about half a million lines in a few months, and his talk explains the checking method he uses so agents can validate their own work.

How it works

  1. Feed documents like slides and PDFs to the tool
  2. Agents write the conversion code
  3. Explicit models and alignment checks let agents validate their own output
  4. The tool converts documents into accessible versions

Why it’s worth knowing

One professor, a few months, and about half a million lines of working code aimed at a legal deadline.
