Creator of Genius Scan [1] here: we are one of the launch partners of OneNote and integrating with the API was easy. Team is also super responsive and "startup" like.<p>To address the "one way" API limitation, I would expect Microsoft to add more endpoints over time and I think it's not a bad strategy to start with that one. Adding a way to post notes to OneNote already enabled a lot of cool integrations...<p>[1] <a href="http://thegrizzlylabs.com" rel="nofollow">http://thegrizzlylabs.com</a>
We (News360) were one of the launch partners for the OneNote API as well and our experience with it has also been really positive - the API itself is pretty simple right now but has all the details right. It's a great foundation to build on, and the team building it seems really committed to keeping the momentum going.<p>Having external tools, both hardware and software, is a huge part of building a memory-augmenting product and I'm really happy that Microsoft is getting it right - OneNote has always been a really interesting product, but it suffered from weird positioning and always felt like an add-on to Office more than anything else. Now that it's being marketed as more of a standalone (and free!) product, I think it has a great chance of becoming much more mainstream.
I'm liking the new API-friendly approach of Microsoft. Once the "get" functionality to retrieve notes exists, I see many possibilities for alt. clients, add-ons and integrations which will make OneNote as a platform more compelling.
What I was able to parse from the documentation, this seems to be "one way" API, meaning that one can only post new notes to OneNote but there's no way to read notes via the API. I was expecting a little more from Microsoft in 2014.
Its interesting to see Microsoft launching startup-like products.. is this an acquisition or did they develop it from scratch?. Anyways this is something I would use; not sure if I would pay for it sometime soon.
