Breaking down the tech stack

ElevenLabs: The voice behind pulse

At the core of Pulse is ElevenLabs, an AI voice synthesis platform. It’s able to create natural, human-like speech, making it perfect for applications requiring real-time text-to-speech functionality. In our project, ElevenLabs powers the real-time voice responses of Pulse. 

Why we choose ElevenLabs: 

• It has an API-first integration, something essential for our project  
• It’s able to speak in a variety of tones and styles, making it more fun 
• It has subscription-based pricing

Neon: For persistent data storage in Postgres 

Pulse wouldn’t be complete without a solution for managing and storing data—and that’s where Neon comes in. Unlike ephemeral in-memory storage or hardcoded responses, Neon provides a reliable way to persist data, ensuring that Pulse can grow in functionality over time.

Next.js: The web app framework

The front-end and back-end of Pulse are powered by Next.js. We used it for the user interface, API requests, and the real-time updates. 

Why we picked Next.js: 

• Built-in server-side rendering for a fast page 
• Simple API routes makes it easy to connect with ElevenLabs and Neon
