Customize the Grammarly agent

The new customization options for the Grammarly agent make it easier to fine-tune your writing preferences and shape how your text is corrected so the suggestions you see are always on point.

How to access

To customize Grammarly, you need one of the following Superhuman or Grammarly products:

How to customize

You can adjust Grammarly suggestions in three different ways:

1. Turn off a certain type of correction directly from the suggestion card

Once you click the three horizontal dots on a suggestion card, you might see an option titled “Hide suggestions like this.” This option is available for certain categories of suggestions, such as the Oxford comma, semicolons, em dashes, and more.

The Grammarly agent, just like classic Grammarly, also corrects full sentences and paragraphs. You’ll now see an open-ended chat field below a full-sentence rewrite suggestion. Click on the Revise or ask a follow-up field and type in custom instructions to change this type of correction moving forward. The instructions will be saved in agent settings for future use.

2. Customize suggestions in the AI Chat

Set your writing preferences exactly how you want, right from the side panel of the Go chat window — “Write AM and PM in uppercase when formatting times,” “Enforce American English dialect,” or some other specific setting that you prefer. The instructions you can set are not limited to a fixed set of rules.

  2. Hover your cursor over the Grammarly agent and click on the three-dot icon that appears.

On this page, you have multiple customization options:

  • Control where Grammarly appears. For instance, you can enable it for emails only. To adjust this setting, click on the Proactive assistance while writing section under Triggers, then scroll down to the Where would you like this agent to help you? section.

  • Manage the blocklist of sites where Grammarly won’t appear. Click on the Proactive assistance while writing section under Triggers and scroll down to the URL Blocklist section. Click + Add to block a domain.

  • Restrict Grammarly from editing specific documents. Click on the Proactive assistance while writing section under Triggers, scroll down to the Custom field, and type in custom instructions.

  • Set your language preferences and manage your dictionary.
