Ziflow enables you to review any type of Google Docs.

To proofread a Google Doc in Ziflow, ensure that the Share settings on the Doc are set to "Anyone with the link". Then, proof it as a "View Live Content" option.

If you want to proof a Google Doc as a static snapshot, we recommend publishing the document to the web first and then uploading the generated URL.

Once the document is published, you can enter the generated URL to Ziflow
to begin a website snapshot proof.

If you don't want to leave the Google Doc published, then you can go to the File -> Publish to the web and click on the Stop Publishing button.
