It has some nice looking templates that I wish my presentation can adopt.
An ex AppSumo deal kroma.ai, which disppeared to become a blog site, also had quite some templates. But it takes hours to put my own content into those templates due to the size, color and fonts. The good thing about Presenti is it will automatically put your text into proper boxes and know how to arrange it to stick to the template's design.

The best part is, it does this really fast like in just seconds.

BUT

It doesn't learn what the content is. So it applies slides to inappropriate templates, if you use an existing presentation. For example I had a summary slide put into a sales planning roadmap with quarters assigned.
And probably due to the use of Gen AI, it changes the non English text to English. That's a big issue, since it would be difficult for me to review all technical/architectural diagrams to ensure all text, large or small, stay as is. Not sure if I missed anything, but once a template is applied there is nowhere for you to re-select another.

The worst problem of them all, is the template filters didn't work properly when I tested it.
Search by style or industries just gave the spinning circle that was still going when I checked the browser tab hours later.

So while it was fun watching the AI put my old presentation into its template. A read-to-present presentation became unpresentable. That's counterproductive.

I didn't plan on writing this review but after seeing some of the previous reviews, I just feel the urge to come and share what I have experienced. 1 taco for having some nice templates and 1 taco for having the collaboration feature (co-editing) and for being fast.
