Here is what they have to say
The Google Docs integration is currently available to users on Claude Pro and Claude for Work (Team or Enterprise) plans. For more information on enabling Google Docs within your account, visit the resource here. Connect your Google Docs directly to Claude to provide additional context for your conversations. You can easily add documents by pasting URLs or selecting from your recent documents, helping Claude better understand and assist with your tasks.
