Inspiration
We wanted to make digital payments simpler, smarter, and more accessible through conversational AI. Managing transactions and understanding payment information can sometimes be confusing. This inspired us to build PayPilot AI Voice Agent, an AI-powered assistant that helps users interact with payment-related information using natural language and voice.
What it does
PayPilot AI Voice Agent is an AI-powered payment assistant designed to make payment interactions easier.
- Provides an AI chat interface for payment-related questions.
- Supports voice input and spoken AI responses.
- Integrates with PayPal Sandbox for testing payment workflows.
- Allows users to create and capture test payment orders.
- Helps users access transaction-related information.
- Uses AI provider integrations to generate conversational responses.
How we built it
We built PayPilot AI Voice Agent using a modern full-stack architecture.
- Frontend: React and Vite
- Backend: Python and FastAPI
- Payments: PayPal Sandbox integration
- AI: OpenAI, Gemini, and Groq integrations
- Voice: Browser Speech Recognition and Speech Synthesis
- Search: Tavily integration
- Deployment: GitHub and cloud hosting
The frontend communicates with the backend through API endpoints. The backend manages AI requests, transaction-related operations, and PayPal Sandbox payment workflows.
Challenges we ran into
During development, we faced several challenges:
- Integrating the frontend with the FastAPI backend.
- Connecting AI providers and managing fallback responses.
- Implementing voice input and speech output in the browser.
- Handling microphone permissions and different browser voices.
- Integrating PayPal Sandbox order creation and payment
