## Project Title **Build an AI WhatsApp Chatbot Integrated with a Wiki Knowledge Base using Hexabot AI** ## Project Description We are looking for an experienced developer to build an AI-powered chatbot on WhatsApp, integrated with a Wiki-based knowledge base. The chatbot should use Retrieval-Augmented Generation, or RAG, to answer user questions based on the content stored in the Wiki. The project also requires a scheduled workflow that extracts documents and content from Google Drive, processes them, and populates or updates the Wiki automatically. The Wiki will act as the main knowledge base used by the chatbot. **Experience with Hexabot AI is required.** Please review the Hexabot repository before applying: [[login to view URL]]([login to view URL]) ## Project Objectives The goal is to build a complete working system where: 1. Content is stored in Google Drive. 2. A scheduled workflow extracts and processes Google Drive content. 3. The processed content is published or synchronized into a Wiki. 4. The Wiki acts as the knowledge base. 5. The WhatsApp chatbot receives user questions. 6. The chatbot retrieves relevant information from the knowledge base using RAG. 7. The chatbot generates accurate, contextual responses through WhatsApp. ## Main Requirements ### 1. Hexabot AI Setup and Customization The chatbot must be built using **Hexabot AI**.

The RAG retrieval against a Wiki knowledge base is the tricky bit here since Hexabot's vector store needs to stay synced with Wiki updates without duplicating embeddings. I'd set up a scheduled workflow that pulls from Google Drive, processes docs into chunks, pushes them to the Wiki via API, then triggers a re-index job to update the vector database. The WhatsApp bot would query that vector store through Hexabot's NLU pipeline with OpenAI embeddings and use GPT for response generation. I've built similar RAG pipelines before with FastAPI and PostgreSQL vector extensions. You can check out some of that work at ffulb.com. Once I take a look at your WhatsApp Business API credentials, OpenAI key, Google Drive API access, and the server setup where you want Hexabot deployed, I can confirm the exact approach and get started.

Hello, I got the idea of your project. You need a Hexabot AI based WhatsApp chatbot that uses RAG with a Wiki knowledge base, automatically synced from Google Drive. The key challenge is reliable data syncing, clean document processing, and accurate retrieval with low hallucination in real-time WhatsApp responses. Another challenge is building a stable pipeline between Google Drive → Wiki → Vector DB → Hexabot. Before proceeding, I have some technical questions: Which WhatsApp provider do you prefer (Twilio or Cloud API)? Do you already have a Wiki platform selected or should I choose one based on API flexibility? Expected document volume for embeddings per day? I am suitable for this because I have strong experience in Node.js, API integrations, Docker, and RAG-based chatbot systems. I will use Hexabot workflows, Google Drive API sync service, and a vector DB (Qdrant or pgvector) with scheduled jobs. Deliverables include full chatbot setup, integrations, and documentation. P.S: My current bid is a placeholder bid, cost and scope will be finalized after discussion. I would like to share my portfolio via chat Thank you, Muhammad Abrar

Your biggest challenge isn’t building a WA chatbot it’s creating a reliable knowledge system where Google Drive documents Wiki content RAG retrieval and WA conversations stay synchronized while delivering accurate answers with minimal hallucinations. Most AI bots fail because the knowledge pipeline becomes outdated or inconsistent. That’s exactly what I do. Here’s what I’ll build for you 1 A complete Hexabot-based AI assistant integrated with WA Business API and connected to a centralized Wiki knowledge base for structured content management 2 An automated Google Drive synchronization workflow that extracts documents processes content updates Wiki pages and prevents duplicate or outdated information 3 A production-ready RAG pipeline with document chunking embeddings semantic search and vector storage to ensure accurate context-aware responses based on approved knowledge only 4 A scalable architecture using Hexabot workflows custom actions webhooks and API integrations with full logging monitoring documentation and deployment support Everything will be structured so you can later expand the system with additional document sources multilingual support advanced workflows and new AI capabilities without rebuilding the core architecture. I’d like to understand whether you already have a preferred Wiki platform and hosting environment or if you would like recommendations based on scalability maintenance and API flexibility requirements.
