Create Mask

Create precise object masks using simple text prompts—no manual selection required.

Overview

The Create Mask tool allows you to automatically isolate any object in an image by describing it in plain text. Fluidfit’s AI detects the subject and generates accurate masks in seconds, helping you work faster with full control over each element.

You can also invert masks or combine multiple masks into a single mask—all without manual drawing.

What You Can Do with Mask

Object-level segmentation for people, products, apparel, faces, and backgrounds
Background removal and replacement with clean, accurate edges
Targeted effect application (color, blur, lighting, texture, style) on specific regions
Multi-object control with options to invert or combine masks
Advanced compositing support for cutouts, overlays, and scene assembly

How It Works

1. Drag & Drop Media Node
Add the Media node to the canvas and upload your source image.

2. Add Create Mask Tool
Drag the Create Mask tool and connect it to the Media node.

3. Enter Prompt
In the Create Mask tool, describe what you want to isolate (e.g. face, dress, person, background).

4. Invert & Compositing Mask (Optional)

Enable Invert Mask to select everything except the defined subject.
If multiple objects are detected, use Composite Masks to merge them into a single mask for a single output.

6. Generate Output
Click Generate to get AI-powered, precise masks with full control.

Note: If there are more than 1 objects identified, you will get all those masks separately to provide you the better control on each object and use Compositing Mask feature to merge them into a single mask.
