With Transform, whenever an AI rewriting assistant transforms your text, MerciApp shows you exactly what changed — word by word. Additions appear highlighted in green, and deletions are shown with strikethrough.

## **Show changes on the fly**
After each generation from a rewriting assistant, a "Show changes" button appears at the bottom right of the response area.

1. Click **"Show changes."**
2. Additions appear highlighted in green, and deletions are shown with strikethrough.
3. Click **"Hide changes"** to go back to the final result, without any annotations.

This button is available on all rewriting assistants, at any time.

## **Enable changes display by default on a custom assistant**
By default, MerciApp's built-in assistants don't automatically highlight changes — but you can turn this on whenever you need it.

To have an assistant automatically highlight changes with every generation:

1. Create a new assistant or duplicate an existing one.
2. In the creation form, under the **"Highlighting…"** section, enable the **"Show"** option.
3. Save your assistant.

From that point on, changes will automatically show up with every generation for that assistant.

|| **Tip:** You can always click "Hide changes" — even on an assistant that's set to show them by default.

**Good to know:** If more than 85% of your text was modified, the changes won't be displayed.
