Sozi review (2026): is it any good?
Zooming presentation editor that animates over an SVG poster
Sozi report card
Good · out of 4.0 · graded Nov 13, 2026
Best for zooming presentations over one big SVG poster
Sozi animates movement around a single SVG poster, working with Inkscape. It is free software with desktop releases for three systems, but the latest news on its site is from 2021.
Who Sozi is for
- Fits if you already draw in Inkscape
- Works for talks that suit one big map or poster
Who Sozi is not for
- Skip it if you want conventional slides in order
- Watch out: the latest release news is dated 2021, so development looks slow
- Watch out: Linux repositories carry very outdated versions, says the install page
- Not for you if you do not use Inkscape, since it builds on SVG files
Why Sozi gets a 2.8
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- AValue for moneyFree software under the Mozilla Public License 2.0 that anyone can download and run.
- AFree plan and trialEverything is free and it asks only for donations.
- CFeaturesIt animates a poster view by view and does that job fully, but needs Inkscape and a different layout from ordinary slides.
- CEase of useNo store rating is on record. You design the whole poster first, so there is a learning curve.
- CPlatforms and integrationsPrograms for Windows, Mac and Linux only, plus Inkscape. No phone or web version.

Keep Sozi, or make your own?
Keep it
Sozi is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces. It is one of the better ones too: its GPA of 2.8 is higher than 78 of the 89 other presentation tools we grade.
What you could not
- A slide editor.
- A diagram editor.
- Apps for macOS, Windows and Linux that stay in step with each other.
What this rests on. Sozi’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
