Handle real estate SMS inquiries with Twilio, Google Sheets, Gemini, and Calendar
Quick overview Youtube Explanation: https://youtu.be/e_07nGFmVs0 This workflow replies to inbound Twilio SMS messages with property details and viewing scheduling help by looking up leads and properties in Google Sheets, using a Google Gemini agent with Redis chat memory, and checking/booking appointments in Google Calendar. How it works Receives an inbound SMS via Twilio. Looks up the sender’s mobile number in a Google Sheets “leads_info” spreadsheet and appends/updates the lead record if it does not exist, extracting a 4-digit property code from the message when available. Splits any saved semicolon-separated property IDs into individual lookups, fetches matching property rows from a Google Sheets “Property details” spreadsheet, and compiles a summary of found vs. missing property codes. Sends the user message, lead context (saved property IDs and email), current time, and the property-lookup results to a Google Gemini chat agent with Redis-backed conversation memory. Lets the agent optionally use tools to fetch additional property info from Google Sheets, update the lead’s email or interested property IDs in Google Sheets, and check or create viewing events in Google Calendar.

Generate structured drama scripts from webhook requests using OpenAI and Google Sheets
Quick overview This workflow accepts a webhook request with a drama topic, genre, tone, and size constraints, uses Python-based genre classification plus OpenAI GPT‑4.1 to generate a full script as structured JSON, then returns the script to the caller and appends a summary log entry to Google Sheets. How it works Receives a POST webhook request containing the script topic, genre, tone, language, act count, and character count. Normalizes inputs by applying defaults, clamping acts to 1–5 and characters to 2–8, and adding request metadata like a request ID and timestamp. Classifies the genre in Python and prepares genre-specific guidance used to shape the script structure, then filters out requests marked as invalid. Sends the prepared parameters and genre guidance to OpenAI (GPT‑4.1) to generate a complete drama script as a single JSON object. Parses and validates the AI response as JSON, falls back to a safe wrapper if parsing fails, and enriches the result with counts for acts, scenes, and characters. Waits briefly and then returns the structured script to the webhook caller while also appending a summary row to a Google Sheets tab for tracking. Setup Configure the Webhook trigge
Send crowd safety SMS reroute alerts with OpenAI, Twilio, and Google Sheets

WMatch packing list PDFs to purchase orders with docling-serve and Ollama
Quick overview This workflow checks an SFTP “pending” folder for packing list PDFs, converts them to OCR text with docling-serve, and uses Ollama (Gemma) to extract structured line items and match them to a purchase order, logging results and moving files to completed or error folders. How it works Runs every hour and lists files in the SFTP pending folder. Filters for PDFs, downloads each file from SFTP, and logs a PENDING status to an n8n Data Table. Uploads the PDF to docling-serve for OCR conversion (RapidOCR, English) and stops with an error status if conversion fails. Sends the converted Markdown text to an Ollama Gemma chat model to extract a normalized packing-list JSON (PO number, parties, and line items). Loads the matching purchase order data and cross-references PO vs packing-list SKUs and quantities to determine whether the document matches. If SKU count matches but SKU text differs, uses an Ollama-based healing step to detect likely OCR-misread SKUs, applies the corrections, and re-runs the cross-reference. Writes the final status (COMPLETED or ERROR) to the n8n Data Table and moves the PDF in SFTP into a folder named after the status (for example, completed/ or error
WTriage and reply to email threads with GPT-5.2, IMAP, Gmail, and ESP suppression
Quick overview Automatically read inbound email replies, use AI to detect intent and sentiment, and send natural in-thread responses. Opt-out requests are confirmed, pushed to your ESP suppression list, and logged. A hands-off reply layer that keeps your sender reputation clean while every conversation gets fast, human-sounding answer. How it works An IMAP trigger watches your inbox and picks up new reply emails as they arrive. A filter keeps only genuine replies, and a code node strips quoted history and signatures, then parses the sender name, email, and threading headers. A code node builds a strict AI prompt with the cleaned message and your trigger-word hints. The OpenAI node classifies intent and sentiment and drafts a reply, returning strict JSON. A code node normalizes the response, enforces a clean email structure, and adds your CTA once. A switch routes on the unsubscribe flag: normal replies go back in-thread through Gmail, opt-outs get a neutral confirmation. Opt-outs are posted to your ESP suppression list, every action is logged to a data table, and Gmail labels are updated to mark the thread handled. Setup (5 steps): Add your IMAP credentials to the email trigger and
