Presio

Present PDF slideshows with a controller window and a mirrored viewer. Local by default: your PDF stays in your browser — nothing is uploaded unless you choose to sync. Log in to share a session code and present live across devices, with speaker notes and embedded media.

How it works

Upload a PDF to get a controller view with slide navigation, speaker notes, and media. Open a viewer window to mirror the controller, or sync online for a six-character session code that viewers can join from any device. Recent presentations stay available on the home page, and local decks work offline.
