I need a JavaScript-based chatbot that lives on my website and does two things well: 1. On load it must call [login to view URL] and present those predefined questions to the visitor. 2. Whenever the visitor types free-form text, the bot answers with text-only replies generated by an NLP layer. My preference is to start with a proven open-source NLP library (for example Natural, [login to view URL], or another you recommend) and enrich it with our own rules. I already store keywords and patterns in a MySQL table called NLP_MODEL, so the final solution should blend statistical intent detection with regex / keyword matching pulled from that table. If you see a cleaner technical approach, feel free to propose it. The chatbot must speak English, Spanish, French, and Romanian, selecting the right language automatically or via a simple user toggle. Deliverables • Clean, well-commented JavaScript code for the chat widget • REST call that fetches and refreshes the predefined Q&A list • NLP module wired to the MySQL NLP_MODEL table, including the table schema or migration script • Configuration or README explaining how to train, extend, and deploy the model and how to add more languages later I value maintainable code and clear instructions so I can keep expanding the knowledge base after hand-off. Specifications and sample files / code source in attached document.

Hi, We’ve developed similar chatbots that use predefined questions and NLP to generate answers from free-form text. One of our solutions, called “AskCody,” uses Azure’s NLP to extract intent and provide answers from a knowledge base. We also built a custom web app to manage Q&A pairs, allowing admins to add, edit, and delete entries. For your project, we can use a combination of NLP libraries and regex to create a hybrid model that’s more accurate than relying on NLP alone. We can also integrate a language detection library to automatically switch languages based on user input. Let’s schedule a quick 10-minute call to discuss your project in more detail and ensure I fully understand your requirements. I’m looking forward to hearing more about this exciting project. Best regards, Adil

Hello, I can deliver a lightweight JavaScript chatbot that integrates directly into your site. On load, it fetches and displays predefined questions from your API, and for free-form input it responds using an open-source NLP engine combined with rule-based matching from your existing NLP_MODEL MySQL table. The bot will support English, Spanish, French, and Romanian with auto-detection or a simple language toggle. You’ll receive well-structured, commented code, the REST integration, NLP–MySQL wiring, and clear documentation so you can easily extend intents, rules, and languages later.
