AURIA

Accessible Unified Response Intelligence Assistant

A Proof of Concept built at the OpenClaw Global Unhackathon São Paulo.

Overview

Smart protection for the ones you love.

AURIA is a voice-activated AI security system designed to protect women, the elderly, and children. It enables discreet emergency alerts through Telegram, using AI to interpret voice messages and automatically trigger phone calls to trusted contacts.

The Problem

Victims of violence often cannot call for help through conventional means in the moment of danger. Traditional safety apps require pressing panic buttons or downloading dedicated apps, which may not be accessible in critical situations.

The Solution

AURIA provides a discreet, voice-activated digital guardian that:

• Voice Activation: Just speak - no buttons to press
• No Extra App: Uses Telegram (already installed on most phones)
• Humanized Call: Realistic AI voice via ElevenLabs
• Instant Response: From voice to rescue in seconds

Demo & Context

Pitch Deck

Full presentation explaining the problem, solution, and vision.

Telegram Audio Processing

User sends an audio message to the OpenClaw bot. The AI transcribes the audio using Whisper, interprets the intent, and triggers the N8N workflow to initiate an emergency call.

N8N Workflow

The workflow receives webhook calls from OpenClaw and makes HTTP requests to ElevenLabs API for voice generation.

N8N MCP Server Configuration

MCP Access configuration showing the server URL and the "AI Tinkerers OpenClaw" workflow available for execution.

AURIA Calling Demo
