 ### Create embeddings to enable AI-powered similarity search.
-[Embeddings](https://en.wikipedia.org/wiki/Embedding_(machine_learning)) are numeric vectors that you can create for data (like a text or an image) to capture meanings, contexts, or relationships related to the data. You can then search the data by running intelligent queries over its embeddings using [vector search](../../ai-integration/vector-search/vector-search_start) to find content by similarity rather than exact match.
-- RavenDB allows you to create embeddings using native [ongoing embeddings-generation tasks](../../ai-integration/generating-embeddings/embeddings-generation-task) that systematically process document collections and convert document fields (like texts or arrays) into embeddings. To create the embeddings, the tasks can use either an external AI model (such as OpenAI) or RavenDB's default embedding model.  
-- You can also create embeddings using external embeddings providers and store them in your database (e.g., to handle other content types such as images).  
-- You can avoid pre-generating embeddings, and let vector search operations generate embeddings on-the-fly, while searching.  
-- Embeddings can be used by other RavenDB AI features. E.g., [AI agents](../../ai-integration/ai-agents/ai-agents_start) can use vector search to retrieve relevant data requested by the LLM.  
+
+* [Embeddings](https://en.wikipedia.org/wiki/Embedding_(machine_learning)) are numeric vectors that represent the meaning, context, or relationships within the data (e.g., text or images).
+  They allow you to search for similar content using [Vector search](../../ai-integration/vector-search/vector-search_start), rather than exact matches.
+
+* RavenDB can generate embeddings automatically using [Embeddings-generation tasks](../../ai-integration/generating-embeddings/embeddings-generation-task) that you define.
+  These tasks process text fields from documents and convert them into vectors using either an AI model from external providers 
+  (e.g., [OpenAI](../../ai-integration/connection-strings/open-ai)) or [RavenDB’s built-in model](../../ai-integration/connection-strings/embedded).
+  The resulting vectors are stored in a dedicated collection in your database.
+
+* Alternatively, you can skip pre-generating embeddings via _Embedding-generation tasks_ and let RavenDB generate them on-the-fly during dynamic vector search queries.
+  Learn more in [Vector search using a dynamic query](../../ai-integration/vector-search/vector-search-using-dynamic-query). 
+
+* RavenDB does not generate embeddings for non-text content such as images.
+  However, you can import embeddings for such content from external providers and store them in your database for similarity search.
+
+* Embeddings also power other AI features in RavenDB, such as [GenAI](../../ai-integration/gen-ai-integration/gen-ai_start) and [AI agents](../../ai-integration/ai-agents/ai-agents_start),  
+  which may use vector search queries to retrieve relevant documents in response to LLM requests.
