Presentz is a mashup, as it merges things like Vimeo, Youtube, Slideshare and Speakerdeck. But you can use images and video files as well, unleashing the HTML5 video tag power.
Last but not least, Presentz is opensource. Check out our git repo and help us make it better.
Start making your own presentation: as you log in, the "MAKE" button in the top menu will lead you to "Presentz Maker", our editor.
Once it's done and published, your presentation will be listed on your personal page: log in and click on your name to see it.
The purpose of Presentz is to allow everyone to faithfully reproduce presentations and conference talks, without imposing any technology constraint.
Most alternatives to Presentz have a centralized approach: you give them your video or audio, your slides, you use their tool to mix them, and they will host and publish the result.
We don't. There are enough streaming and slide sharing services available without us making another. And if you prefer to host your files on your own, do that. With Presentz you just mix them all.
As of now, we support the following video services: Youtube, Vimeo, your own video files. And the following slide services: Slideshare, Speakerdeck, Rvl.io, your own Flash files and images. Take a look at the demos to see them working.
Thank you for your interest in Presentz.
