The Brush Tool allows you to paint directly onto your image, making it ideal for drawing new elements, guiding AI changes, or marking specific areas to modify. It’s especially powerful when combined with selection tools and prompt-based generation.
See how drawing over assets with the Brush Tool, combined with Lasso selection and AI prompts, gives you full control over creative edits.
Overview
With the Brush Tool, you can add paint strokes directly onto your canvas to visually indicate what you want to change or add. After drawing, you can select the painted area, write a prompt to guide AI, and then generate new results while keeping your original image intact.
How It Works
 | Select the Brush Tool from the toolbar. |
 | Choose a color using the color wheel, or use the eyedropper to sample a color from your existing asset. Adjust brush size and opacity in the brush settings for better control. |
 | Draw directly onto your image to indicate where you want to make changes or additions. Once finished, use the Lasso Tool to select the area you just painted. |
 | Make sure the selected style matches the style of your base image for consistency. |
 | Write your prompt, describing the asset you want to generate. You can enable the auto-enhancer or enhance prompt option to improve your prompt quality. |
 | Lower the similarity setting, especially in draw-over cases. This helps the AI distinguish your brushstrokes from the intended output. |
 | Click Forge in Selected Area, and generate multiple outputs. Choose a result from the forges menu on the right. |
 | You can Accept the forge onto the current layer or add it to a new layer from the dropdown menu. |
Best Practices
Use brush strokes to sketch or block out ideas visually before prompting the AI.
Keep similarity low for draw-overs to avoid the AI trying to replicate your brush marks.
Always confirm that your art style selection matches your original image to ensure consistency.
Try forges on a new layer if you're testing ideas and want to keep your base image untouched.
