Interactive AI Learning Platform with Real-Time Chatbot

Project Overview

I developed a comprehensive interactive learning platform that brings together cutting-edge AI technology with real-time communication to create an engaging, personalized educational experience. At the heart of this platform is SOUL, an AI mentor that guides users through their learning journey with natural conversations in both text and voice.

The Challenge

Traditional online learning platforms often feel disconnected and impersonal. Users struggle with static content, lack of real-time feedback, and no sense of continuity in their learning journey. We wanted to create something different—a platform where users could have natural, flowing conversations with an AI mentor that remembers their progress, celebrates their achievements, and adapts to their learning style.

The Solution

We built a full-stack learning platform that combines three powerful technologies working together seamlessly:

Real-Time Interactive Chatbot

The platform features a sophisticated chatbot that users can interact with through both text and voice. What makes this special is how it works in real-time—there's no waiting, no delays. When you speak or type, the AI responds instantly, creating a natural conversation flow that feels like talking to a real mentor.

The technical magic behind this involves WebSocket technology, which creates a persistent connection between your device and our servers. Think of it like a phone call that stays open—instead of hanging up after each message, the connection remains active, allowing for instant back-and-forth communication. This enables features like:

Voice Activity Detection: The system knows when you're speaking and when you've finished, so it can respond at the perfect moment
Streaming Responses: You see and hear the AI's responses as they're being generated, not after it's completely finished
Session Persistence: If your connection drops momentarily, the conversation picks up exactly where you left off—the AI remembers everything you discussed

Advanced WebSocket Architecture

Building a reliable real-time system required solving complex challenges. We implemented multiple layers of connection management:

Connection Monitoring: The system continuously checks if the connection is healthy, sending small "heartbeat" messages every 30 seconds. If something goes wrong, it automatically detects the issue and reconnects without you even noticing.

Session Resumption: One of the most impressive features is how the system handles interruptions. If your internet connection drops or you close your browser, when you come back, the AI remembers your entire conversation. It's like resuming a book at the exact page you left off—nothing is lost.

Keepalive Mechanism: To prevent the AI session from timing out during quiet moments, the system sends subtle signals every two minutes. This ensures that even if you pause to think, the conversation stays active and ready when you return.

Multi-Modal Communication: The platform handles both audio and text simultaneously. You can speak your questions and receive audio responses, or type and get text replies. The system intelligently manages both formats, switching between them seamlessly based on your preferences.

Gamification and Achievement System

To make learning engaging and motivating, we built a comprehensive badges and awards system. Users earn achievements for various milestones:

Streak Master: Rewards consistent learning over multiple weeks
High Achiever: Celebrates exceptional performance on tasks
Profile Pro: Encourages users to complete their profile
Objective Achiever: Recognizes completion of learning objectives
Chapter Completion: Tracks progress through different learning modules
Journey Completion: The ultimate achievement for completing the entire program

Each badge comes with points, visual rewards, and a sense of accomplishment. The system automatically tracks your progress and awards badges when you meet the criteria, creating a game-like experience that keeps users motivated and engaged.

Memory and Personalization

What truly sets this platform apart is how the AI remembers your journey. Unlike typical chatbots that forget everything after each conversation, SOUL maintains a comprehensive memory of:

Your past conversations and insights
Your personal goals and definitions of success
Your struggles and breakthroughs
Your performance across different tasks
Your values and what matters to you

This memory system allows SOUL to reference past conversations naturally. When you're working on a new task, the AI might say, "Remember when you defined success as achieving work-life balance? Let's build on that." This creates a sense of continuity and personalization that makes the learning experience feel truly tailored to you.

The technical implementation involves storing conversation data in a vector database, which allows the AI to search through your entire learning history to find relevant context. When you start a new conversation, the system retrieves your past interactions and weaves them into the current discussion, creating a seamless learning journey.

Payment Integration with Razorpay

To support a sustainable business model, we integrated Razorpay, a leading payment gateway, to handle subscriptions and one-time payments. The implementation goes beyond simple payment processing to create a seamless, secure experience.

Smart Currency Detection: The system automatically detects the user's location and suggests the appropriate currency (USD, INR, etc.), making payments feel natural regardless of where users are located. This detection is cached intelligently to avoid unnecessary API calls while ensuring accuracy.

Payment Link Generation: When users select a subscription plan, the system generates a secure payment link that's pre-filled with their information. This link can be shared, saved for later, or used immediately. The system supports partial payments, allowing flexibility for users who need it.

Webhook Security: All payment confirmations are verified using cryptographic signatures. This ensures that only legitimate payments from Razorpay are processed, protecting both the platform and users from fraud.

Subscription Management: The system tracks subscription status, payment history, and automatically updates user access levels when payments are confirmed. Users can see their subscription details, payment history, and manage their plans all in one place.

Payment Recovery: For payments that are initiated but not completed, the system maintains records and allows users to claim or complete payments later. This reduces lost revenue from abandoned payment flows.

Multi-Currency Support: The platform handles multiple currencies seamlessly, converting amounts appropriately and ensuring users see prices in their local currency. This makes the platform accessible to a global audience.

Diverse Task Types and Intelligent Evaluation

The platform supports four distinct types of learning tasks, each designed for different learning objectives and evaluated using appropriate methods:

1. Read & Learn Tasks (Read-Only) These are informational tasks where users engage with content—reading materials, watching videos, or exploring resources. Completion is straightforward: once users have viewed the content, the task is marked complete. This type is perfect for introducing new concepts or providing foundational knowledge before more interactive tasks.

2. Action Form Tasks These tasks require users to fill out structured forms with specific questions. The AI evaluates the responses based on predefined criteria, looking for depth, completeness, and alignment with learning objectives. Users receive detailed feedback on their submissions, and the task is only marked complete when the AI determines the responses meet the quality threshold.

The evaluation considers:

Completeness of responses
Depth of understanding demonstrated
Alignment with task objectives
Quality of reflection and thought

3. AI Conversation Evaluation Tasks These are open-ended learning experiences where users engage in extended conversations with SOUL. The AI continuously assesses the user's engagement, comprehension, and application of knowledge throughout the conversation. Completion isn't based on specific answers but on the AI's holistic assessment that the user has sufficiently engaged with and understood the concepts.

The AI evaluates:

Quality of questions asked
Depth of understanding shown through responses
Application of concepts in discussion
Overall engagement and participation

4. Reflection & AI Assessment Tasks These tasks prompt users for specific reflections on their learning. The AI then evaluates these reflections for depth, understanding, and adherence to the prompt. This type is ideal for helping users synthesize their learning and demonstrate comprehension through personal reflection.

The evaluation focuses on:

Depth of reflection
Personal insights and connections made
Understanding demonstrated through examples
Alignment with the reflection prompt

Intelligent Scoring System

All evaluated tasks use a scoring system (0-100%) with configurable thresholds. Tasks can have different passing thresholds—some might require 80% while others are more lenient at 50%. The AI provides detailed feedback explaining the score, highlighting strengths, and suggesting areas for improvement.

When users don't meet the threshold, they receive constructive feedback and can retry the task. The system tracks all attempts, allowing users and administrators to see progress over time. High-scoring completions are flagged and can unlock special badges, creating additional motivation for excellence.

Technical Architecture

The platform is built using a modern, scalable architecture:

Frontend (React/TypeScript): A responsive web application that provides the user interface. It handles real-time WebSocket connections, manages audio playback, and creates an intuitive user experience.

Backend (Laravel/PHP): A robust server that manages user accounts, tracks progress, handles authentication, and coordinates between different services. It stores all user data, conversation history, and achievement records.

AI Service (Python): A specialized service that handles the AI interactions. It connects to Google's Gemini AI, manages the conversation flow, processes audio streams, and implements the memory retrieval system.

Vector Database (Pinecone): Stores user memories and conversation history in a format that allows for intelligent searching and retrieval, enabling the AI to find relevant past interactions quickly.

Key Features and Innovations

Seamless User Experience

The platform feels incredibly smooth because of how all these technologies work together. When you interact with SOUL, you're not aware of the complex systems running behind the scenes—you just experience natural, flowing conversations. Whether you're browsing subscription plans, completing a task, or chatting with the AI, everything flows naturally.
