Where Google Docs fits
Use it when classmates or coworkers need to draft and comment on the same document.
Check before you choose
It is primarily a web service; offline access and available features depend on account settings, browser and device.
Find the right edition
Start with the destination for your device or the publisher's website. Use the current requirements and terms there to confirm the edition you need.
Compare the workflow
Separate personal notes, office documents and shared project tracking when comparing options. Local files offer a different ownership model from a hosted workspace, and synchronization is not a substitute for a backup.
