# Collection

The **Collections** feature lets you generate descriptions for multiple products within selected collections. This is especially useful if you have a large catalog, as **bulk generation** is limited to 250 products per batch, while collections have no such restriction.

**How to Generate Descriptions for Collections**

1. **Navigate to the Collections Page**
   * Similar to Shopify’s collection page, you can search and sort to find the collections you want.
2. **Select Collections**
   * Tick the checkbox for up to **5 collections** at a time.
3. **Generate descriptions for products**
   * Click the **Generate Descriptions for Products** action to open a modal where you can customize generation options.
   * Once ready, click **Generate** to proceed.

**Managing Collection Generations**

To track and manage your collection-based generations, go to the **Bulk Page**. Collections will be listed with **Type = "Collection"** for easy identification.

**Syncing to Shopify**

After the generation process is complete, you can choose to **sync all to Shopify** to save the updates to your store.
