# AI Bulk Generation

The Bulk App allows you to process multiple images at once using a single prompt. Upload several images, apply the same prompt to all of them, and download the results together.

## Start a Bulk Session

### Upload Images

Drag and drop multiple images into the upload area or click to select files from your device.

Supported formats include:

* JPG / JPEG
* PNG
* WEBP

You can upload several images at once. Each image will appear in the **Bulk Input List**.

### Review Uploaded Images

After uploading, the images will appear in the Bulk Input List.

For each image you can:

* Preview the image
* Add a custom prompt for each image
* Remove it from the list before starting the generation

⚠️ Only valid images will remain in the list. Unsupported formats or invalid images will be rejected.

### Enter a Prompt

Type a prompt describing how the images should be processed.

The same prompt will be applied to **all uploaded images**.

Example prompts:

* "Change the background to a beach"
* "Convert the image into a watercolor painting"
* "Remove the background and place the object in a studio setting"

***

### Start the Bulk Generation

Click **Start** to process all uploaded images.

The Bulk App will generate results for each image individually while showing their progress in the results list.

Each image will display a status such as:

* in progress
* failed
* completed

## View Bulk Results

After processing begins, each image will appear in the **Bulk Results List**.

For each result you can:

* View the generated image
* Expand the image preview
* Download the result individually

## Download All Results

Once the generation is complete, you can download all images at once.

Click **Download All** to receive a ZIP file containing all generated images.

The ZIP file includes:

* All processed result images
* Each file named according to its source image

***

## Restore Previous Bulk Sessions

You can reopen previous Bulk sessions.

### Open a Session

Click **Sessions** to view previously created sessions.

A list of past sessions will appear.\
Each session includes the images that were processed in that batch.

### Load a Previous Session

Select a session from the list.

The Bulk App will restore:

* The original input images
* The generated results

You can review the images or download them again.

## Bulk Notes

* Each Bulk session processes all images with the **same prompt and settings**.
* Large batches may take longer depending on the number of images.
* Sessions can be reopened later to access previously generated results.

## Start a Serial App Session

The **Serial App** allows you to process images step by step, where each step builds on the result of the previous one.

### Upload Image

Drag and drop one image into the upload area or click to select files from your device.

Supported formats include:

* JPG / JPEG
* PNG
* WEBP

### How to use the Serial App

1. **Switch to Serial App mode**\
   Use the toggle at the top to switch from **Bulk App** to **Serial App**.
2. **Upload an image**\
   Drag and drop an image into the upload area or click to select a file from your device.\
   Supported formats: **JPG, JPEG, PNG, WEBP**
3. **Create your process steps**
   * You can add up to **7 steps**
   * Each step applies a transformation to the image
   * The output of one step is automatically used as the input for the next
4. **Configure each step**\
   When adding a step, you can:
   * Choose which image to use (original or previous outputs)
   * Define the prompt or transformation for that step

### Example workflow

1. **Step 1:** Change the product color (e.g., make the mattress red)
2. **Step 2:** Use the result from Step 1 to generate a close-up shot
