Desktop Edition Architecture (Go Backend & Local Compute)

Go-Driven Distributed Edge Capture and Localized RAG.

In complex internal environments where centralized mirroring is unfeasible, the CXMind Desktop Agent leverages a high-performance Go-based backend. This service directly utilizes the local computing power of the agent's PC for audio processing and RAG storage. This architecture localizes capture and assistance while directing data streams to private ASR/LLM endpoints within the LAN.

1. The Go-Powered Backend Engine

The core of the Desktop Edition is a lightweight Go backend process running as a system service (Daemon). This ensures that core logic remains active even if the frontend UI is minimized.

Local Compute Utilization

Harnesses the agent machine's CPU/GPU for real-time audio re-sampling, feature extraction, and preliminary semantic processing. This distributed model significantly reduces the computational burden on central servers.

Network-Level Interception

The Go engine captures traffic directly at the host machine's network interface. It reliably sniffs SIP signaling and RTP media streams regardless of the softphone or dialer used.

Ultra-Low Resource Footprint

Operating silently in the background, the Go-based service processes bi-directional audio streams (Caller + Agent) with exceptional memory efficiency, ensuring zero packet loss without impacting the agent's daily workflows.

2. Localized RAG & Private Connectivity

This version emphasizes data retention and rapid retrieval capabilities at the terminal side.

  • Localized RAG Storage: The vector index for Retrieval-Augmented Generation (RAG) is stored directly within an encrypted database on the agent's machine. This allows the Copilot to retrieve business scripts and compliance guidelines in milliseconds without external search queries.
  • LAN AI Integration: The Desktop Agent connects to ASR and LLM services within the local network via standard WebSocket/gRPC. In trusted intranet topologies, the system currently prioritizes standard protocols to achieve ultra-low latency.
  • Local Copilot Loopback: The agent's Copilot interface connects directly to the local Go backend. This "local loopback" design ensures that assistance pop-ups are perfectly synchronized with the live call progress.
