Sozi
What it is
Sozi is a presentation editor and player for SVG documents. It arranges content on a freely laid out poster and guides viewers through it with translations, zooms, and rotations rather than a fixed slide sequence. The editor supports creating and saving frames, undoing and redoing changes, and changing keyboard shortcuts in preferences. Conversion to PDF and video is integrated into the presentation editor. Presentations can be embedded in HTML pages with an iframe and controlled from the surrounding page using JavaScript. Sozi is available on the web and for Linux, macOS, and Windows, with offline access and presenter mode listed. It is free software under the Mozilla Public License 2.0, with a free plan at no cost. The Windows distribution is a zip archive without an installer. Linux distribution repositories may offer very outdated versions for which documentation and support are unavailable. The project’s documentation is being rewritten as an online book, and users can seek help through the Sozi users forum.
