Generative AI

RAG–Based Chatbots for Personalized Discovery & Mental Wellness

Overview

Two AI chatbots — Nextflag and Mythful Mind — use Retrieval-Augmented Generation (RAG) to deliver personalized, context-aware experiences. Nextflag is a smart travel companion, while Mythful Mind supports emotional wellness by blending ancient philosophy with modern AI. Together, they showcase the power of combining vector databases, language models, and emotional intelligence.

The Challenge

Most recommendation systems and wellness applications today rely on rule-based logic or keyword-driven searches that fall short in understanding the complexity of human needs.

For hospitality discovery: Users often receive generic or irrelevant recommendations

For hospitality discovery: Conversion suffers due to poor contextual awareness

For hospitality discovery: Apps struggle to offer empathetic, personalized support

For hospitality discovery: Users feel they’re talking to a machine, not a companion

Systems ignore personal tastes, moods, nuanced preferences

Cultural, emotional, and user contexts are often ignored

The Solution

To address these challenges, we built two advanced chatbot systems using the RAG framework: a combination of vector search and generative AI that retrieves the most relevant information and crafts tailored responses.

Vector Search Integration

Uses Pinecone to index thousands of restaurants and hotels based on embeddings.

Topic Modeling Engine

Enables key features like 'vegan-friendly', 'quiet', 'ambience', or 'rooftop view'.

Custom Sentiment Scoring Model

Analyzes user reviews and feedback for quality and preference alignment.

Natural Language Interface

GPT API generates friendly, helpful, human-like responses based on context.

Cloud AI + Pinecone DB Integration

Enables long-term memory and deep recall for more context-aware conversations.

Philosophical & Psychological Core

Draws from Buddhist, Stoic, Sufi, and CBT traditions for holistic support.

Emotional and Cultural Analysis

Analyzes tone, check-in frequency, and cultural cues to tailor responses.

Personalized Emotional Guidance

Delivers prompts, affirmations, and insights based on evolving emotional patterns.
