structure\nThis folder contains the **Scrape latest Paul Graham essays** workflow. Its executable nodes use `chainSummarization`, `documentDefaultDataLoader`, `html`, `httpRequest`, `limit`, `lmChatOpenAi`, `manualTrigger`, `merge`, `set`, `splitOut`, `textSplitterRecursiveCharacterTextSplitter`. The table and connection map below are derived from the JSON, not an inferred guarantee of behavior.\n\n## Setup\nImport inactive. Configure your own credentials and replace REPLACE_WITH_* values. Review external destinations and Code nodes before running.\n\n## Entry points\nWhen clicking \"Execute Workflow\"\n\n## Verification\nSanitized source candidate; not runtime-tested. This overview is generated from node metadata. Read the folder README for the connection map, credential types, and license.\n\n## Attribution\nhttps://github.com/Zie619/n8n-workflows/blob/94007c1445d9258a7da116646b79473e7c7c3282/workflows/Splitout/0318_Splitout_Limit_Automation_Webhook.json\nMIT; preserve source notices.", "width": 700, "height": 800, "color": 1 } } ], "connections": { "Merge": { "main": [ [ { "node": "Clean up", "type": "main", "index": 0 } ] ] }, "Extract title": { "main": [ [ { "node": "Merge", "type": "main", "index": 0 } ] ] }, "Fetch Essay List": { "main": [ [ { "node": "Extract essay names", "type": "main", "index": 0 } ] ] }, "Limit to first 3": { "main": [ [ { "node": "Fetch essay texts", "type": "main", "index": 0 } ] ] }, "Extract Text Only": { "main": [ [ { "node": "Summarization Chain", "type": "main", "index": 0 } ] ] }, "Fetch essay texts": { "main": [ [ { "node": "Extract title", "type": "main", "index": 0 }, { "node": "Extract Text Only", "type": "main", "index": 0 } ] ] }, "OpenAI Chat Model": { "ai_languageModel": [ [ { "node": "Summarization Chain", "type": "ai_languageModel", "index": 0 } ] ] }, "Default Data Loader": { "ai_document": [ [ { "node": "Summarization Chain", "type": "ai_document", "index": 0 } ] ] }, "Extract essay names": { "main": [ [ { "node": "Split out into items", "type": "main", "index": 0 } ] ] }, "Summarization Chain": { "main": [ [ { "node": "Merge", "type": "main", "index": 1 } ] ] }, "Split out into items": { "main": [ [ { "node": "Limit to first 3", "type": "main", "index": 0 } ] ] }, "When clicking \"Execute Workflow\"": { "main": [ [ { "node": "Fetch Essay List", "type": "main", "index": 0 } ] ] }, "Recursive Character Text Splitter": { "ai_textSplitter": [ [ { "node": "Default Data Loader", "type": "ai_textSplitter", "index": 0 } ] ] } }, "active": false }
