🤖 AI Personal Assistant with GPT-4o, Memory & Scheduling for WhatsApp

🤖 AI Personal Assistant for WhatsApp – Modular, Smart & Always Ready

Hi! I’m Amanda — I’ve been creating intelligent agents and automation flows for over 2 years using n8n and Make. This project is one of the most complete personal assistants I’ve ever built.

It’s not just one flow. It’s a modular system where each workflow handles a specific skill — like saving memory, searching custom knowledge, scheduling appointments, or managing prompts — all orchestrated by a central AI brain.

🧠 Core Capabilities

• 💬 Chat with GPT-4o via WhatsApp
• 🧠 Dynamic memory (session-based) using LangChain
• 📚 Personal knowledge base (create, update, delete and search entries)
• 🗓️ Schedule appointments with Google Calendar
• 🧾 Customize assistant personality per user via prompt control
• 🔁 All modular: add/remove features without breaking the main flow
• 🌍 Multi-language and context-aware conversation

📦 Included Workflows

⚠️ IMPORTANT: When purchasing on gumroad, all workflows will be available for download!
