+Collections let you group related documents into searchable databases. Each collection has its own vector index so you can retrieve information based on semantic similarity.
+
+### Opening the collections panel
+
+- Click the **database icon** in the left toolbar or press **Key 4** to open the Collections view.
+- Existing collections appear in a list showing the number of indexed items and the embedding model used.
+- Use the **Create Collection** button to make a new one.
+
+### Creating a collection
+
+1. Enter a unique name.
+2. Choose an **embedding model** from the list. This model converts your documents into vectors for similarity search.
+3. Submit the form. The new collection appears in the list.
+
+### Indexing files
+
+- Drag and drop files onto a collection to add them. A progress bar shows indexing status and an ETA.
+- Supported formats include PDF, PowerPoint, Word, Excel, text, Markdown, HTML and images (with OCR extraction).
+- Any errors during indexing are reported once processing finishes.
+
+### Managing collections
+
+- Click a collection’s workflow name to assign an ingestion workflow. This workflow runs on new files as they are indexed.
+- Use the delete icon to remove a collection. Confirmation is required.
+
+### Using collections in chat
+
+When composing messages, click the **Collections** button in the chat toolbar to select which collections should be searched. The assistant will include results from the selected collections when responding.
+
+Collections are stored locally, giving you full control of your data while enabling powerful document retrieval.
