Generate Image Tools

Automatic detection

You can simply mention @Hana and describe your request. If the intent is clear, she will automatically run the relevant image tool for you.

Introduction

Hana can generate and edit images using the Generate Image tools.

• Edits not applied: Ensure you’ve provided or selected a mask for the area to change.
• Aspect ratios: Specify square, portrait, or landscape if composition matters.
