iA / Writer / Support / Editor / Authorship

Authorship Mac

iA Writer for Mac helps you to distinguish between Human generated text and Other sources (such as AI).

When the feature is enabled you can quickly see the difference in a document:

When you make edits to text as the primary author, your text remains in full focus and you can clearly see where your text ends and externally sourced content starts.

Note: Authorship does not modify your content in anyway and your text is not sent to a server to detect authors. Everything happens locally on your device: Your data is yours, in compliance with our Privacy Policy.

Enable or Disable Authors

You can always mark a selection or paste as any type of author into a document. To see the distinction in the Editor you need to enable the appropriate Editor settings.

You can enable Authorship in one of three ways:

Settings pane EditorAuthors:
Focus Menu Show Authors
Editor’s Title Bar Select the Focus dropdown
Keyboard shortcut A


From ChatGPT

When you copy and paste a conversation from ChatGPT, the copied text contains “You” before every question, and “ChatGPT” before every answer. We recognize this pattern and offer to automatically mark authorship when coming from ChatGPT.

chatgpt authorship

To use it : select the text you wish from ChatGPT and paste into the Editor. You’ll see a prompt letting you choose whether to paste with or without authorship.

Paste As

Apart from ChatGPT, Writer will rely on you defining the authorship by yourself. Pasting content from an external source with Authorship attribution is easy.

With some text on clipboard:

Right-Click Right-click in Editor and select Authors{desired author}Paste
Authors Menu Navigate to menu bar Authors{desired author}Paste as {desired author}
Keyboard Shortcut Paste content as the top secondary author using the keyboard shortcut: V

💡 You can map any menu item including Authors functions. To learn more please see the support article for Shortcuts

Pasting Between Existing Documents

Sometimes you may want to copy/move text from one document to another/ a new one. If your selected text contains author data, iA Writer will give you the option to Paste With Annotations or Paste:

Paste With Annotations Authorship information is retained and added at the end of the of the receiving document.
Paste Text is pasted without Authorship data.

Marking As

When editing documents you can attribute existing text to a specific author. This is helpful not only for your own documents but also for shared/collaborative documents when you wish to clearly discern between authors.

After selecting a range or ranges of text:

Right-Click Right-click in Editor and select Authors{desired author}Mark Selection
Authors Menu navigate to menu bar Authors{desired author}Mark Selection as {desired author}

Keyboard Shortcuts

By default the second author (immediately following you, the primary author) is mapped to the V keyboard shortcut for pasting.

Since the list of Authors is flexible and unique to each user, you can map your own Paste as … and Mark selection as … to any unreserved shortcut. Here’s how:

  1. Navigate to desired Authors menu option
  2. Open macOS Settings
  3. Search: keyboard shortcuts
  4. Select App Shortcuts
  5. Click + and select iA Writer from the list of apps
  6. In            enter the item exactly as it appears in iA Writer’s Authors menu
  7. Click Done

Delete Removes the author and associated data from file. Note: This does not remove Author from the app Settings.

Annotated Files

You can quickly distinguish between files including authorship data and those without. When a file has authorship annotations added, the file icon shows a blue .

iA Writer stores author related metadata at the end of a file. This metadata is tucked out of view in Writer’s editor, but is visible when the file is opened in other text editors/apps.


iA Writer automatically strips author metadata on export to Markdown, HTML, PDF and MS Word.


When sharing annotated files via macOS sharing options (AirDrop, email, from Finder, etc.), all file information including author metadata is shared.
