Prezi is a startup that deserves more than a fair share of attention, if only because it approaches a tried and tested field (that of making online presentations) and it brings some new ideas that leave a lasting and favorable impression on those who try it.
The basis of the whole editor is dispensing with the slideshows that we all have become accustomed to and monumentally fed up with.
Instead of that, Prezi allows you to create zooming presentations that have far more panache.
A tool like Prezi does something which should not be belittled: it reinvents the way you can approach presentations, and it provides a new mean for engaging the audience. The first minutes of a presentation (any presentation) are the key to the whole process. It is like a movie or a song – if it grabs you from the onset, then it will not let go immediately (or at all, for that matter). Prezi enables users to get their ideas across in the most dynamical and pictorial fashion, and that alone turns into a wildcard that fits snugly in any sleeve.
There are several plans for you to choose (including an inexpensive one), as well as endless tutorials and guides (found under the “Learn” banner). These will let you come up with a fine idea of how everything works, and what to expect from Prezi if you decide to give it a whirl.
