Today, Google is officially adding its note taking tool, Keep, to its core G Suite service (formally Google Apps). That means if you’re using a company or school Google account you can finally get access to the excellent Google Keep. They’re also adding access to Keep right in Google Docs.
As far as G Suite integration goes, you should have access to Keep right now from your G Suite account. As for the Docs integration, you’ll find Keep under the Tools menu. Enable it, then you can drag and drop notes from the side panel into your document. Perhaps more useful, you can also highlight text in Docs, right-click it, then select “Save to Keep notepad” to save it as a new note.
