PDF-to-accessible-HTML platform
Public documents like budgets, audits, agendas, and flyers usually go out as PDFs, which many residents with screen readers can't use. This platform turns them into clean, accessible web pages. Staff upload a PDF, the app reads its layout and tables, and AI agents draft the HTML. People then check it at clear review steps: alt text, reading order, and a screen-reader pass. Staff compare the result side by side with the original before anything is published. The web page becomes the main version, and the PDF stays available as a download.
