Step 1 of 4Open Plugins

The walkthrough uses the original ChatGPT web plugin captures. After connecting, open Codex in the desktop app and start a new task with ApexGenius. A ChatGPT web connection does not verify Codex access.

A public ApexGenius plugin listing is not verified. Use a plugin shared with you or one you created, subject to your account and workspace policy.

What Codex can do in Google Docs

2 operations. Read looks things up and changes nothing. Write changes Google Docs and runs only when that tool is enabled.

Read1 operation

Looks things up. Changes nothing.

Read

  • read_docRead a document’s text and structure, with its comments if you ask.

Write1 operation

Changes Google Docs. Runs only when enabled.

Edit

  • update_docInsert, replace, delete and format text, tables, images and comments, or make the edits as suggestions.

You choose what Codex can use

When you approve Codex, pick Full access, Read only, or Custom. Read only allows the Read operations and nothing else. Custom picks apps and tools one by one.

Limits in Google Docs

  • · The connected Google account decides which documents can be read and changed.
  • · Edits can also delete text. Ask for suggestions when you want to review each change first.
  • · Enabled writes run immediately. Turn a tool off to block calls.
  • · Disconnecting stops future access. It does not undo an edit; use the document’s version history.
