ARIA is an AI-powered interactive avatar assistant designed to provide human-like responses and dynamic interactions using Retrieval-Augmented Generation (RAG). It seamlessly integrates knowledge retrieval, reasoning, and real-time engagement, making it an intelligent personal assistant capable of handling various tasks, including email retrieval, calendar management, and Google Drive interactions.
2. Features
2.1 Adaptive RAG Mechanism
Dynamically retrieves relevant context before generating responses, improving accuracy.
Uses vector-based retrieval to provide knowledge-aware interactions.
2.2 Interactive Avatar
Utilizes VRoid Studio to create a lifelike, expressive AI assistant.
Supports text-based and voice-based interactions using speech-to-text (STT) and text-to-speech (TTS).
2.3 Real-Time Learning & Context Awareness
Continuously improves through user interactions and feedback.
Uses metadata-based filtering to refine query results from emails, calendars, and Google Drive files.
3. Technologies Used
3.1 AI
Retrieval-Augmented Generation (RAG) for knowledge-aware responses.
Embeddings and vector search for efficient information retrieval.
Eleven Labs STT & TTS for real-time voice-based interactions.
3.2 Backend & Infrastructure
FastAPI backend for handling API requests.
MongoDB for storing user data
Elastic Search for managing metadata and vectorized documents.
Docker for containerized deployment.
3.3 User Interface & Frontend
React + Next.js + TypeScript for a responsive, modern web interface.
VRoid Studio for avatar rendering and animation.
3.4 Cloud & API Integrations
Google API integration to interact with:
Gmail – Retrieves emails and indexes them for querying.
Google Drive – Downloads selected files, stores them in a vector database, and enables QA over specific folders.
Google Calendar – Handles scheduling, event creation, and event deletion through natural language commands.
4. Functional Capabilities
4.1 Email Retrieval & Querying
Downloads Gmail messages, stores them in a vector database, and enables metadata-based filtering for email search and QA.
Users can ask natural language questions such as:
"What was the last email I received from John?"
"Summarize all emails related to project X last week."
4.2 Google Drive Indexing & Document QA
Allows users to select specific folders in Google Drive for indexing.
Supports querying specific files and folders using natural language, such as:
"Find the report about X in my Drive."
"Summarize the latest meeting notes from my research folder."
4.3 Calendar Scheduling & Management
Understands natural language queries related to Google Calendar and performs actions such as:
Creating new events: "Schedule a meeting with Alex at 3 PM on Friday."
Deleting events: "Cancel my dentist appointment next Monday."
Checking schedules: "Do I have any meetings scheduled for tomorrow?"
4.4 Voice Interaction & Assistant Mode
Supports conversational AI interactions using Eleven Labs STT & TTS.
Can function as a fully voice-enabled assistant that responds in real-time.
5. Usage
Setup a Google Cloud Project with necessary API scopes to connect with Gmail, Google Drive, and Google Calendar to ARIA.
Have the necessary API Keys for ElevenLabs or LLM
Start ARIA – Use text or voice commands to interact with your AI assistant.
Perform Actions – Retrieve emails, manage schedules, search documents, and interact with your avatar assistant.
7. Future Enhancements
Multi-user authentication to support shared workspace environments.
Enhanced conversational capabilities using fine-tuned LLMs.
Integration with additional third-party productivity tools (e.g., Slack, Notion).
ARIA is designed to be a versatile, AI-powered digital secretary, streamlining information retrieval and task automation in a single interactive assistant.
