OVERVIEW

Project Overview

This project aimed to ease the supplement selection process for customers. We developed an AI chatbot that works with users through a guided quiz or natural conversation. Given the user inputs, recommendations are made by the chatbot based on health concerns such as digestion, energy, or immunity.

This system is directly linked to a PostgreSQL database, which means all recommendations are spot-on and current. Whether users describe their symptoms or opt for the quiz, the chatbot retrieves relevant products in real time—delivering a tailored, automated experience right on the website.

We also focused on designing the chatbot to be intuitive and easy to use. The design and flow of interactions were thoughtfully crafted to help users navigate easily, whether they’re just browsing or searching for specific health solutions.

Key Features

AI Email Management

01.

Smart Quiz-Based Interaction

To start each session, the chatbot runs a one-time interactive quiz to learn the user’s health focus. Their inputs are mapped to product attributes within the database so that the chatbot can quickly and efficiently provide users with relevant supplement recommendations immediately following quiz completion.

02.

Conversational Health Query Support

For users who skip the quiz, the chatbot changes to conversation mode. It listens for health-related inputs, for example, “I’m feeling low” and ask follow-up questions to gather the necessary context.

Real-Time Product Recommendation Engine

All suggestions come from a PostgreSQL database with detailed product info like uses, ingredients, and benefits. The chatbot shows product cards with names, short descriptions, and buy links. It uses keyword-based logic to match user input, and an admin panel lets the admin user train the chatbot by uploading keywords and content.

Project Challenges and Their Solutions

1. Continuous Refinement for Keyword Mapping and Chatbot Behavior

Challenges

Throughout the project, the client provided valuable feedback. The primary concern was improving chatbot responses and keyword accuracy. Although these refinements continued with the system, they were beneficial in getting the chatbot closer to user or brand expectations.

SOLUTIONS

To support this type of continuous improvement, we wanted to create a way for the system to be flexible and easy to maintain. In the admin panel, we set up a way for updates to be made (when necessary) from uploading one or two documents (PDF or Word files). This allowed the client to update keyword mappings with source documents or to update the chatbot logic without involving a developer. This ensured quick iteration cycles and fine-tuned user experiences, even post-deployment.

2. Real-Time Product Suggestions from Natural Language

Challenges

A primary requirement was the ability to offer product suggestions based on user input in real-time — structured quiz responses, or conversational health queries. The system needed to pull meaningful insights from user language and respond appropriately and reliably with relevant supplement suggestions, without relying on third-party APIs or pre-produced product filters.

SOLUTIONS

We implemented a robust data retrieval layer using PostgreSQL and File Search Integration tool. After processing user input, and their follow up responses, the system utilized key context from the user input and matched into the relevant real-time product data. This architecture allowed for a fast and reliable suggestion process and an overall seamless user experience facilitated by live database logic.
