OK it doesn't have all the bells and whistles of Prezi, BUT what you do get, works well and costs you zero. You are able to do a very decent presentation with it. I STRONGLY recommenced you search Youtube to watch 20 minutes of tutorials just to save you two hours of working it out for yourself. The main difference is you design in a separate program like Inkscape before importing your main vector image into Sozi. Thank you Sozi team I like it !!

We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
I think that you could check Sozi: https://sozi.baierouge.fr. - Source: Hacker News / over 1 year ago
Https://slidedog.com/ has a free option but I don't know how restrictive it is. They don't talk about it much so obviously want you to upgrade to pro. Source: almost 3 years ago
