Sozi

Sozi is a zooming presentation editor and player.

Unlike in most presentation applications, a Sozi document is not organised as a slideshow, but rather as a poster where the content of your presentation can be freely laid out. Playing such a presentation consists in a series of translations, zooms and rotations that allow to focus on the elements you want to show.

If you ever need your own local Prezi, this is an option.

This tool allows WYSIWYG editing of impress.js presentations.

Alpha version, though. A bit rough around the edges.

GitPitch

GitPitch is a service by developers for developers that generates beautiful, slideshow presentations directly from PITCHME.md markdown found in GitHub, GitLab and Bitbucket repos.

Yet another presentation tool. Looks useful though.
