Diff Visualization

See exactly what TabMail wants to change with visual diff highlighting. Accept edits line by line or all at once.

How it works

When TabMail suggests changes to your draft, you’ll see visual diff highlighting:

• Green highlighting — Text being added
• Red highlighting — Text being removed

This diff view lets you review every change before accepting it.

Accepting edits

• Press Tab to accept the current suggestion
• Press Shift + Tab to accept all remaining suggestions at once
• Keep typing to dismiss the suggestion and continue writing
• Select a part of the diff and press Tab to accept it

Visual feedback

TabMail’s diff highlighting is designed to be clear without being distracting:

• Suggested additions appear inline where they’d be inserted
• Deletions are shown with strikethrough styling
• Colors adapt to light and dark mode automatically

Undo support
