Aiva Backend - README
š Overview
The Aiva Backend powers the AI virtual assistant functionality for the Aiva mobile app. It is built with Node.js and designed to interact with users intelligently through natural language, summarization, reminders, and email-based interactions.
This backend acts as an AI agent using the Gemini model, deployed on a DigitalOcean VPS, and provides secure API endpoints for chat interaction, content summarization, reminder scheduling, and smart email replies.
š§ Core Capabilities
š¤ AI-Powered Chat Agent
Integrates with Gemini to engage in natural human conversations
Used by the mobile client (React Native app) to simulate intelligent dialogue
