+Creating a Document Editor with AI and delta changes a faster way. 
+
+## 1. **Use Tiptap's Transaction API**
+
+Instead of replacing the entire document, create transactions that apply specific changes:
+
+```javascript
+// Your chatbot returns structured commands
+const chatbotResponse = {
+  message: "I've added a security section and updated the introduction.",
+  edits: [
+    {
+      type: "insertHeading",
+      position: 150,
+      level: 2,
+      text: "API Security Best Practices"
+    },
+    {
+      type: "insertParagraph", 
+      position: 151,
+      text: "Implement rate limiting and input validation..."
+    },
+    {
+      type: "replaceText",
+      from: 45,
+      to: 67,
+      text: "comprehensive security protocols"
+    }
+  ]
+};
+
+// Apply changes using Tiptap transactions
+function applyEdits(editor, edits) {
+  const tr = editor.state.tr;
+
+  edits.forEach(edit => {
+    switch(edit.type) {
+      case 'insertHeading':
+        tr.insert(edit.position, editor.schema.nodes.heading.create(
+          { level: edit.level },
+          editor.schema.text(edit.text)
+        ));
+        break;
+
+      case 'insertParagraph':
+        tr.insert(edit.position, editor.schema.nodes.paragraph.create(
+          {},
+          editor.schema.text(edit.text)
+        ));
+        break;
+
+      case 'replaceText':
+        tr.replaceWith(edit.from, edit.to, editor.schema.text(edit.text));
+        break;
+    }
+  });
+
+  editor.view.dispatch(tr);
+}
+```
+
+## 2. **Position-Based Updates with Node IDs**
+
+Add IDs to your document structure for reliable targeting:
+
+```javascript
+// Configure Tiptap with node IDs
+const editor = new Editor({
+  extensions: [
+    StarterKit,
+    // Add ID extension for trackable nodes
+    Document.extend({
+      addGlobalAttributes() {
+        return [
+          {
+            types: ['heading', 'paragraph', 'bulletList'],
+            attributes: {
+              id: {
+                default: null,
+                parseHTML: element => element.getAttribute('data-id'),
+                renderHTML: attributes => {
+                  if (!attributes.id) return {};
+                  return { 'data-id': attributes.id };
+                },
+              },
+            },
+          },
+        ];
+      },
+    }),
+  ],
+});
+
+// Chatbot references nodes by ID
+const edits = [
+  {
+    type: "updateNodeById",
+    nodeId: "intro-paragraph-1",
+    content: "Updated introduction text..."
+  },
+  {
+    type: "insertAfterNode", 
+    nodeId: "section-2-heading",
+    nodeType: "paragraph",
+    content: "New paragraph after section 2..."
+  }
+];
+```
+
+## 3. **Semantic Section Management**
+
+Create helper functions to work with document sections:
+
+```javascript
+class DocumentManager {
+  constructor(editor) {
+    this.editor = editor;
+  }
+
+  findNodeById(id) {
+    let foundNode = null;
+    this.editor.state.doc.descendants((node, pos) => {
+      if (node.attrs.id === id) {
+        foundNode = { node, pos };
+        return false; // stop iteration
+      }
+    });
+    return foundNode;
+  }
+
+  insertAfterNode(nodeId, nodeType, content) {
+    const found = this.findNodeById(nodeId);
+    if (!found) return;
+
+    const tr = this.editor.state.tr;
+    const insertPos = found.pos + found.node.nodeSize;
+
+    const newNode = this.editor.schema.nodes[nodeType].create(
+      { id: `generated-${Date.now()}` },
+      this.editor.schema.text(content)
+    );
+
+    tr.insert(insertPos, newNode);
+    this.editor.view.dispatch(tr);
+  }
+
+  updateNodeContent(nodeId, newContent) {
+    const found = this.findNodeById(nodeId);
+    if (!found) return;
+
+    const tr = this.editor.state.tr;
+    const newNode = found.node.type.create(
+      found.node.attrs,
+      this.editor.schema.text(newContent)
+    );
+
+    tr.replaceWith(found.pos, found.pos + found.node.nodeSize, newNode);
+    this.editor.view.dispatch(tr);
+  }
+}
+
+// Usage
+const docManager = new DocumentManager(editor);
+
+// Apply chatbot edits
+chatbotEdits.forEach(edit => {
+  switch(edit.type) {
+    case 'updateSection':
+      docManager.updateNodeContent(edit.sectionId, edit.content);
+      break;
+    case 'addAfterSection':
+      docManager.insertAfterNode(edit.afterId, edit.nodeType, edit.content);
+      break;
+  }
+});
+```
+
+## 4. **Range-Based Updates**
+
+For more complex edits, use Tiptap's range utilities:
+
+```javascript
+import { findChildren } from '@tiptap/core';
+
+function applyRangeEdit(editor, edit) {
+  const { from, to, content, nodeType = 'paragraph' } = edit;
+
+  const tr = editor.state.tr;
+
+  // Create new content
+  const nodes = content.map(text => 
+    editor.schema.nodes[nodeType].create({}, editor.schema.text(text))
+  );
+
+  // Replace range with new nodes
+  tr.replaceWith(from, to, nodes);
+  editor.view.dispatch(tr);
+}
+
+// Chatbot can specify ranges to replace
+const edit = {
+  type: "replaceRange",
+  from: 100,
+  to: 250,
+  content: [
+    "Updated first paragraph...",
+    "New second paragraph..."
+  ]
+};
+```
+
+## 5. **Integration with RAG System**
+
+Structure your RAG prompt to return Tiptap-compatible edits:
+
+```javascript
+const prompt = `
+You are editing a document using Tiptap editor. Return your response as JSON with:
+1. "message": Your conversational response
+2. "edits": Array of edit operations
+
+Available edit types:
+- insertAfterNode: {type, afterNodeId, nodeType, content, id}
+- updateNode: {type, nodeId, content}
+- replaceRange: {type, from, to, content}
+- insertAtPosition: {type, position, nodeType, content, id}
+
+Current document structure: ${getDocumentStructure()}
+User request: ${userMessage}
+`;
+
+// Process RAG response
+async function handleChatbotResponse(userMessage) {
+  const response = await callRAG(prompt);
+  const parsed = JSON.parse(response);
+
+  // Show conversational response
+  displayChatMessage(parsed.message);
+
+  // Apply document edits
+  applyEditsToDocument(parsed.edits);
+}
+```
+
+## 6. **Track Changes for Undo/Redo**
+
+Tiptap handles this automatically, but you can add custom tracking:
+
+```javascript
+// Before applying edits
+const beforeState = editor.state;
+
+applyEdits(editor, chatbotEdits);
+
+// Add to custom history if needed
+addToChangeHistory({
+  type: 'chatbot-edit',
+  before: beforeState,
+  after: editor.state,
+  timestamp: Date.now()
+});
+```
+
+This approach lets you make precise, incremental changes to your Tiptap document without regenerating the entire content. The editor's transaction system ensures smooth updates and maintains undo/redo functionality.
