Good for long writing assignments
What do you like best?
I like that Google Keep is unobtrusive to use while using Google Docs. You can copy notes from Google Keep into Docs easily, so it is a good way to keep track of ideas as you go along. It is easy to use and does not get in the way of the document you're typing.
What do you dislike?
I wish that you could make checklists in the same note and mark things as done as you go along. I also wish there were a tutorial to show you how to use it most effectively.
Recommendations to others considering the product:
I recommend to use Google Keep with Google Docs to help yourself stay organized. It's much easier than switching between an idea dump document and the document you're typing.
What problems are you solving with the product? What benefits have you realized?
I use Google Keeps to plan, write, and revise long writing assignments for my college classes. Particularly in the revision stage, it is very helpful to be able to copy my professor's feedback to Google Keep and be able to refer back to it without having to use split screen or switch between multiple tabs.
