Stumbled upon Slidewise trying to resolve an issue with unsupported fonts that wouldn't save in my PPT. It helped me to quickly resolve that issue, and I discovered how easy it helped with other issues. My course developers know how to use slide masters and so things stay organized. But when you get PPTs from clients its often a mess, with folks copy/pasting slided from multiple decks into one single deck, which snowballs into wierd issues down the road. Slidewise made it so much easier to clean up stuff like this. I feel this software is a good value for what you get, and the time it can save you - especially if you work with folks with little/no training on how to use PPT properly.
