About Google Docs
With Google Docs, you can write, edit, and collaborate wherever you are. Access your docs from your phone, tablet, or computer even when there's no connection.
Working as a Team - Multiple people can work at the same time, and every change is saved automatically.
You can comment, chat and real-time editing on a single document with teammates or people outside your company.
Then you can see edits as others type, communicate through builtin chat and ask questions through including comments.
Google Docs is part of the collaborative tools in gmail and Google WorkSpace and if you want to know more about Google WorkSpace, resellers like Lwegatech can help.
