Here’s how it works:
- You create an account at Presefy, then upload your presentation from your computer.
- You head on over to Presefy on your phone, log in, and hit the “Play” button next to whichever presentation you’re trying to show
- You point any computer attached to any display to your channel’s unique URL (e.ghttp://www.presefy.com/gregkumparak). The presentation pops up on screen immediately
- You swipe from slide to slide right from the web interface on your phone, and the onscreen slides react accordingly.
Oh, and another cool trick: since it’s all being pushed over the web anyway, you can have just about as many people viewing the presentation on their own laptops as you want. No more straining to see what the slide says just because the dude who made it decided to put all of his bulletpoints in 8 pt. Comic Sans. College professors can give lectures without the folks in the back needing binoculars.
Presefy is currently free, though the team is working on a Pro plan with features like password-protected presentations, downloadable presentations, and the ability for viewers to go between slides without screwing with the main display. The service only plays friendly with Powerpoints and PDFs at the moment (folks on Keynote will have to export to something else), but the team says other formats are coming soon.
The one catch: since this is all done through the browser, you’ll want to make sure the venue you’re presenting at has solid connectivity. In a college classroom or a meeting room at your favorite VC’s office? Sure. At a tech conference with 5,000 people all chorking up the connection? This might not the best solution.
