AI-powered lab receptionist built in n8n. Uses an AI Agent with Google Sheets AI Tools (no Workflow Tools/sub-workflows) to check service availability, prices, turnaround times, and clinic info — with memory for multi-turn conversations. # HealthLab Africa — AI Receptionist 🧪 An AI-powered virtual receptionist for a medical diagnostics laboratory, built entirely in **n8n** using only **AI Agent Tools** — no Workflow Tools or sub-workflows. This project was built as a learning exercise to understand how n8n's AI Agent node reasons, routes between multiple tools, and uses memory — before moving on to more advanced Workflow Tool patterns. --- ## What it does The receptionist (named **Ada**) chats with customers and can: - Check whether a lab test/service is available - Look up prices - Look up turnaround times - Answer general clinic questions (hours, address, phone, email, home sample collection, payment methods) - Remember the conversation across multiple messages - Refuse to guess — it only answers using data pulled live from Google Sheets The Agent itself decides which tool(s) to call based on the customer's message — there is no manual IF/Switch routing logic anywhere in this workflow. --- ## Google Sheets structure One spreadsheet, four tabs: | Tab | Columns | |---|---| | **Services** | Service ID, Service Name, Category, Available, Description | | **Price** | Service Name, Price | | **Turnaround** | Service Name, Turnaround Time | | **Business** | Question, Answer | Each AI Tool is scoped to exactly one tab — e.g. the Price Tool can only ever read the Price sheet, which is what enforces the "never mix up prices and availability" rule structurally, not just via prompting. --- ## Key design rules - The Agent **never answers from memory or guesses** — every factual claim (availability, price, turnaround, business info) must come from a live tool call. - If a tool finds no matching row, the Agent must explicitly say the service isn't offered — not stay silent or assume. - The Agent only offers next steps that map to an actual tool (price, turnaround, availability, business info) — it does not invent capabilities like appointment booking or test-preparation guidance, since no tool or da …
