Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.8
GPA, above 78 of the 89 other presentation tools we grade
Sozi is a free editor and player for zooming presentations. Instead of a slideshow, the content is laid out as one poster, and playback is a series of translations, zooms and rotations that focus on parts of it. It is free software under the Mozilla Public License 2.0.
To get you started, here are 8 things to know about Sozi, taken from its own pages and our grades.
You design the whole poster first, so there is a learning curve.
- 1
Best for zooming presentations over one big SVG poster
Sozi animates movement around a single SVG poster, working with Inkscape.
- 2
It is free
Sozi has no paid plan at all. Free software under the Mozilla Public License 2.0.

Windows, macOS and Linux.

- 7
A 2.8 GPA, above 78 of 89

The report card
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.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | Free software under the Mozilla Public License 2.0 that anyone can download and run. |
| Free plan and trial | A | Everything is free and it asks only for donations. |
| Features | C | It animates a poster view by view and does that job fully, but needs Inkscape and a different layout from ordinary slides. |
| Ease of use | C | No store rating is on record. You design the whole poster first, so there is a learning curve. |
| Platforms and integrations | C | Programs for Windows, Mac and Linux only, plus Inkscape. No phone or web version. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Sozi is for
- Fits if you already draw in Inkscape
- Works for talks that suit one big map or poster
Who it 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- Watch out: Linux repositories carry very outdated versions, says the install page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
Good to know
Good for
- Presenters who want Prezi-style zooming without a subscription
- Inkscape users, since the site lists it as a related project
Worth knowing
- The latest release news on the site is dated 2021, so development looks slow.
- Distribution repositories carry very outdated versions, according to the install page.
- Presentations are laid out as one poster, which suits some talks better than a conventional slide order.

Part 04 · Standing
Where it stands
Its grades against its category, and whether to keep it or make your own
78/89
Other presentation tools it is graded above
Sozi's GPA of 2.8 is higher than 78 of the 89 other presentation tools we grade, and level with 3.
It stands best on free plan and trial (A, above 77 of 89) and worst on platforms and integrations (C, above 3).
Sozi has no paid plan.
On features, ease of use and platforms it scores 2.0 out of 4. Nothing scores higher for less, though at least one tool matches that score at a lower price.
Each grade against the category
Every bar is all 90 presentation tools we grade, cut by the letter each got. Sozi’s own letter is outlined.
- AValue for moneyAbove 75 of 89

What paid plans start at, a month (each step along is roughly double) →
Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
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.
