Technical info

Introduction

LensTalk is a cutting-edge AI-powered video-call assistant designed for real-time, responsive communication. Hosted on Cloudflare Workers and leveraging a serverless architecture, LensTalk ensures high availability and fault tolerance for a seamless user experience.

Technical Overview

  • Hosting Environment: LensTalk operates on a Cloudflare-powered Workers environment, delivering responses from the user’s closest server.
  • Failover Support: If a server fails, LensTalk reconnects through the nearest fallback server while maintaining active connections.
  • Architecture:
  • Data Transport: Uses WebSocket for client-server communication and eventemitter3 for lightweight event-based communication.
  • Real-Time Updates: Frontend uses an EventEmitter context for notifying components about AI responses, enabling reactive UI updates.
  • Load Balancing: Cloudflare KV stores active client information to safely rotate servers during high workloads without disruption.

Security and Compliance

  • Garbage collectors clean up disconnected sessions to comply with regulations.
  • No user data or AI-generated data is stored or accessed by LensTalk.
  • A single data parser evaluates payloads for harmful content, rejecting flagged connections and deleting associated data.

Key Functionalities

  • Audio: Uses JavaScript’s AudioContext with a 16kHz sample rate, transmitting audio chunks every 500ms. Only human-voice-containing chunks are processed by the AI.
  • Video: Captures sharp images from video feeds using a canvas, detecting scene changes with a diffing algorithm. Only changed scenery is sent as payloads.
  • Dedicated Instances: Provides separate LensTalk instances for users with customizable API infrastructure.

Features

  • Blazing-fast CDN for content delivery.
  • Worldwide edge-computing infrastructure powered by Cloudflare.
  • Incremental updates pushed on GitHub.
  • Automated CI/CD for seamless deployment.
  • PR previews for testing changes before production.
  • Full customization options, including branding.
  • Always free for a single backend/frontend bundle (pay-as-you-go for additional instances).
