Claude AI analyzes the content and creates a detailed tutorial outline with sections, narration scripts, and visual types. The workflow generates audio narration using Google Text-to-Speech, creates visual scenes with code highlights and terminal animations, and renders the complete video using Remotion. Finally, it uploads the video to YouTube and backs it up to Google Drive.\n\n### Setup steps\n\n1. Configure Claude AI credentials (Anthropic API key) in the \"Analyze with Claude AI\" node\n2. Set up Google Cloud Text-to-Speech API credentials with service account authentication\n3. Configure Remotion API credentials for video rendering (requires Remotion account)\n4. Add YouTube OAuth2 credentials for video uploads with upload permissions\n5. Add Google Drive OAuth2 credentials for backup storage\n6. Activate the workflow to enable the webhook endpoint\n7. Send POST requests to the webhook URL with JSON body: {\"documentationUrl\": \"https://docs.example.com/guide\"}\n8. Monitor executions and check YouTube for published videos\n\n### Customization\n\nModify narration voice settings in \"Generate Narration Script\" node. Adjust video resolution, FPS, and codec in \"Create Visual Scenes\" node. Customize code editor themes and terminal styles. Change YouTube category and privacy settings. Add custom intro/outro animations or branding overlays." }, "typeVersion": 1 }, { "id": "0192412c-8687-4011-916a-facadefe8835", "name": "Sticky Note1", "type": "n8n-nodes-base.stickyNote", "position": [ -816, 60 ], "parameters": { "color": 3, "width": 640, "height": 276, "content": "## Content Extraction\n\nFetches documentation and extracts text, code blocks, and structure" }, "typeVersion": 1 }, { "id": "f71c72f0-d66d-4444-b267-733074e14ace", "name": "Sticky Note2", "type": "n8n-nodes-base.stickyNote", "position": [ -104, 12 ], "parameters": { "color": 3, "width": 464, "height": 324, "content": "## AI Analysis & Planning\n\nAnalyzes content and creates structured tutorial outline" }, "typeVersion": 1 }, { "id": "b3b6bd0b-0f4d-40ec-90b3-50953a0209f3", "name": "Sticky Note3", "type": "n8n-nodes-base.stickyNote", "position": [ 480, -4 ], "parameters": { "color": 3, "width": 672, "height": 340, "content": "## Audio & Visual Generation\n\nGenerates narration audio and creates visual scenes with code/terminal animations" }, "typeVersion": 1 }, { "id": "5bfc9a35-e284-4d79-8ec8-aa7e02e52318", "name": "Sticky Note4", "type": "n8n-nodes-base.stickyNote", "position": [ 1224, -4 ], "parameters": { "color": 3, "width": 1104, "height": 436, "content": "## Video Rendering & Distribution\n\nRenders final video and uploads to YouTube and Google Drive" }, "typeVersion": 1 }, { "id": "97795e7b-6fa8-461f-a61f-4232b2be1ea1", "name": "Mistral Cloud Chat Model", "type": "@n8n/n8n-nodes-langchain.lmChatMistralCloud", "position": [ -24, 400 ], "parameters": { "options": {} }, "credentials": { "mistralCloudApi": { "name": "" } }, "typeVersion": 1 }, { "id": "88da4deb-0bb5-4756-970e-d0891dc88302", "name": "Claude AI to analyze documentation", "type": "@n8n/n8n-nodes-langchain.agent", "position": [ -96, 176 ], "parameters": { "options": {} }, "typeVersion": 3 }, { "id": "e9a3b491-2a0c-4fbd-9112-949b140675e9", "name": "Upload to Youtube", "type": "n8n-nodes-base.youTube", "position": [ 1728, 80 ], "parameters": { "title": "your_title", "options": {}, "resource": "video", "operation": "upload", "categoryId": "=nji876tfcxswe34567yhgnmklp09", "regionCode": "IN" }, "credentials": { "youTubeOAuth2Api": { "name": "" } }, "typeVersion": 1 }, { "id": "18088e03-edfa-4aff-a8f4-a80d0b3ef877", "name": "Generate Audio with Google TTS1", "type": "@n8n/n8n-nodes-langchain.agent", "position": [ 704, 176 ], "parameters": { "options": {} }, "typeVersion": 3 }, { "id": "1dcf0768-8cce-4e4a-9c5e-c9fd2cf8aad9", "name": "Google Gemini Chat Model", "type": "@n8n/n8n-nodes-langchain.lmChatGoogleGemini", "position": [ 776, 400 ], "parameters": { "options": {} }, "credentials": { "googlePalmApi": { "name": "" } }, "typeVersion": 1 } ], "active": false, "settings": { "executionOrder": "v1" }, "versionId": "420a851d-9ef4-4da0-9a78-b1181227bb35", "connections": { "Webhook Trigger": { "main": [ [ { "node": "Fetch Documentation", "type": "main", "index": 0 } ] ] }, "Compile Response": { "main": [ [ { "node": "Respond to Webhook", "type": "main", "index": 0 } ] ] }, "Upload to Youtube": { "main": [ [ { "node": "Compile Response", "type": "main", "index": 0 } ] ] }, "Check Render Status": { "main": [ [ { "node": "Backup to Google Drive", "type": "main", "index": 0 }, { "node": "Upload to Youtube", "type": "main", "index": 0 } ] ] }, "Fetch Documentation": { "main": [ [ { "node": "Parse Documentation Content", "type": "main", "index": 0 } ] ] }, "Create Visual Scenes": { "main": [ [ { "node": "Render Video with Remotion", "type": "main", "index": 0 } ] ] }, "Backup to Google Drive": { "main": [ [ { "node": "Compile Response", "type": "main", "index": 0 } ] ] }, "Google Gemini Chat Model": { "ai_languageModel": [ [ { "node": "Generate Audio with Google TTS1", "type": "ai_languageModel", "index": 0 } ] ] }, "Mistral Cloud Chat Model": { "ai_languageModel": [ [ { "node": "Claude AI to analyze documentation", "type": "ai_languageModel", "index": 0 } ] ] }, "Generate Narration Script": { "main": [ [ { "node": "Generate Audio with Google TTS1", "type": "main", "index": 0 } ] ] }, "Render Video with Remotion": { "main": [ [ { "node": "Check Render Status", "type": "main", "index": 0 } ] ] }, "Structure Tutorial Outline": { "main": [ [ { "node": "Generate Narration Script", "type": "main", "index": 0 } ] ] }, "Parse Documentation Content": { "main": [ [ { "node": "Claude AI to analyze documentation", "type": "main", "index": 0 } ] ] }, "Generate Audio with Google TTS1": { "main": [ [ { "node": "Create Visual Scenes", "type": "main", "index": 0 } ] ] }, "Claude AI to analyze documentation": { "main": [ [ { "node": "Structure Tutorial Outline", "type": "main", "index": 0 } ] ] } } }
