“Office Lens trims, enhances and makes pictures of whiteboards and docs readable, and saves them to OneNote. You can use Office Lens to convert images to PDF, Word and PowerPoint files too.”
I’ve been using it for the last week I’m really liking it! It’s simple, elegant, and very easy to use. The biggest thing I love about it is that it smoothly flattens images taken at an angle. Super helpful!
