ADT Studio is built for teachers, editors and accessibility specialists — not engineers. Every choice in the app follows four principles so your work is always safe, transparent and under your control.

ADT Studio converts existing curriculum PDFs into fully accessible, interactive textbooks — text-to-speech, image descriptions, sign-language video, easy-read, interactive exercises, offline access — built to WCAG and Universal Design for Learning standards, every output human-validated. The hardest step (static PDF → designed, accessible web experience) is now near one-shot through vision-in-the-loop. The users are the people who make national learning content: ministries, publishers and curriculum developers, with teachers next.
