# How do I edit text with AI?

Highlight any text and use Refine to improve the writing, change the tone, or make it shorter or longer. You can keep or undo every change.

Coassemble's AI text editing, called **Refine**, lets you adjust your course content without rewriting it. Highlight any text, choose how you want it changed, and you'll see the result instantly with the option to keep it or undo.

## Refine your text

1. While editing a screen, highlight the text you want to change.  
2. Select **Refine**.  
3. Choose one of four options (below).  
4. Review the result, then select **Keep** to apply it or **Undo** to go back to your original.

## The four Refine options

- **Improve writing:** sharpens clarity and readability for an online learning audience, fixes grammar, spelling, and punctuation, and keeps roughly the same length.  
- **Change tone:** rewrites in one of three tones, Informal & Conversational, Academic & Research-Based, or Motivational & Persuasive.  
- **Make shorter:** condenses the text by about 30 to 50% while keeping the key points.  
- **Make longer:** expands the text by about 50 to 100%, adding relevant detail, examples, or context.

## Frequently asked questions

### Can I undo a change?

Yes. After each refine you can select Keep to apply it or Undo to restore your original text, so you're always in control.

### Can I refine the same text more than once?

Yes. Refine a section as many times as you like, adjusting tone, length, or clarity until it feels right.

### What tones can I choose?

Informal & Conversational, Academic & Research-Based, and Motivational & Persuasive.
