N8N Marketing Workflow

An autonomous marketing assistant within a single n8n workflow: an AI-powered Telegram chatbot that analyzes Instagram/Facebook posts and Meta Ads performance, then executes ad boosts following a one-click approval via an inline button. It features budget safety caps (max IDR 200k/day, IDR 500k total), automated weekly and monthly reports sent to Telegram, historical archiving to Google Sheets (an 8-tab ledger), deterministic content scoring (Scale / Keep Testing / Pause / Do Not Repeat), and shortcut commands like `/sync`, `/summary`, and `/recommendations`. It solves a classic SME pain point—the need for a full-time media buyer despite having fragmented data and history—by consolidating all analysis, approvals, and reporting into a single chat interface.

WellNest Clinic — AI Front Desk

AI receptionist for a wellness clinic: visitors ask administrative questions and book, reschedule, or cancel appointments — with a human always one tap away. Staff manage the same appointments and conversations from a dashboard, and every answer is grounded in approved clinic knowledge via Postgres + pgvector retrieval and Gemini.

Switchboard — AI Business Inbox

AI business inbox and task automation: incoming messages are classified by intent, measured against policy, routed to a department, and either handled automatically or held for human approval. Every decision stores its intent, confidence, policy, and reasoning — and without an OpenAI key the pipeline falls back to a deterministic classifier so the demo never breaks.

Firstpass — AI Lead Qualification

AI lead qualification and follow-up: each lead is normalized, understood, structured, and scored by rules in code — then the engine decides the next action, drafts a reply, and schedules the follow-up, persisting every step for audit and replay. The model extracts and drafts; the score and routing stay repeatable and auditable.
