Onenote, Microsoft’s answer to Evernote has come a long way and as it recently has been even released to all major platforms free of charge (www.onenote.com)
The Office lens is an extension you can use to capture notes and it trims, enhances and makes pictures of whiteboards and docs readable, and saves them to OneNote.
Or how Microsoft advertises it:
Office Lens is like having a scanner in your pocket. Never miss notes on whiteboards or blackboards. Always find important documents or business cards. Don’t lose receipts or stray sticky notes again!
