i3Dify

i3Dify turns PDFs, slides and images into interactive 3D that students actually open: flipbooks that turn like paper, photo albums, gallery walls and 3D phone or laptop mockups. Teachers upload a file, pick a format and share one link or embed it in their LMS or class site. It runs in the browser, needs no installs or 3D skills, and exports mp4 videos. Free plan with 3 projects; Pro is $3 a month.
