LINE AI Chatbot with Gemini and ChatGPT is a hands-on course in building a LINE Official Account chatbot in Node.js that answers with the Gemini API or OpenAI API, remembers conversations, uses RAG over product data and hands chats over to staff. It suits Node.js developers and IT teams at businesses that serve customers on LINE, and you leave with a prototype bot running on Cloud Run.
LINE Official Account is the main channel Thai customers use to contact shops and businesses, yet admins struggle to keep up with questions about prices, stock, order status and the same queries over and over. Older bots that reply by keyword or intent can only answer questions someone prepared in advance. LLMs such as Gemini and ChatGPT understand everyday language far better, but wired straight into LINE the bot forgets the conversation, quotes prices that do not exist and never knows when to let an admin take over.
This course shows learners how to build a LINE OA chatbot in Node.js that answers with AI and the business's own data. Learners set up the Messaging API and webhook, connect the Gemini API and OpenAI API through a common layer that can switch models, keep conversation memory per user, reply with Flex Messages and Quick Replies, and let the bot check stock and order status through function calling. They then add RAG over product data and FAQs, design handover to admins with a case summary, put guardrails and PDPA controls in place and deploy to Cloud Run. It closes with a capstone chatbot for a sample business. (2 days, 6 hours per day, 12 hours in total, Intermediate level.)
Course Details
The course runs for 2 days, 6 hours per day (12 hours in total, 09:00-16:00), as lectures with labs built on a single sample shop throughout. Intermediate level. It focuses on LINE OA chatbots that answer with LLMs, which sets it apart from the Dialogflow LINE chatbot course built on intents, from LINE Workflow Automation with Claude Code & MCP, which covers internal automation, and from LINE LIFF and
MINI App Development, which covers web pages inside the LINE app. Learners use their own or company accounts. The free LINE OA plan has a limited push message quota, the Gemini API has a free tier, and the OpenAI API and Google Cloud Run are billed by usage and need a billing account. Learners take home a lab guide, Node.js code for every lab and a prototype capstone project with a Dockerfile.
