You can add, edit, rearrange, disable, and delete Knowledge Chunks, as well as add metadata to them. This way, you can ensure the accuracy and relevance of the knowledge you provide to your AI Agents. You can't save empty Knowledge Chunks. To access the Chunk editor, select a Knowledge Store in **Build > Knowledge**, then a [Knowledge Source](/ai/agents/develop/knowledge-ai/knowledge-source/overview). ## Explore the Knowledge Editor The Chunk editor includes the Knowledge Chunks in the Knowledge Source as numbered text fields. Clicking the Knowledge Chunks opens the Knowledge Chunk in a new window and displays two areas where you can edit [Knowledge Chunk texts](/ai/agents/develop/knowledge-ai/knowledge-chunk/knowledge-chunk#knowledge-chunk-text) and [Chunk metadata](/ai/agents/develop/knowledge-ai/knowledge-chunk/knowledge-chunk#chunk-metadata).
