If you are exclusively or mostly using a Chromebook for your research and writing, RefWorks is the best citation manager to use.
Because it is in the cloud, RefWorks doesn't require a separate app or downloaded software. It also integrates with Google Docs (something Endnote does not do), so if you are using Google Docs for your writing RefWorks is the better choice.
RefWorks for Google Docs is a plugin for Google Docs that lets you run a simplified version of RefWorks inside of Google Docs. RefWorks for Google Docs enables you to access and cite your references while working in Google Docs.
