Map model downloads, providers, web tools, sync, telemetry, and remote access for the exact configuration you use.

First successful setup

  1. Install the product from its official source.
  2. Choose one model that fits your machine.
  3. Get one simple local response before adding integrations.

What success looks like: one known model loads and returns a normal response before advanced settings are added.

Choose something else when

  • assuming every enabled tool is local;
  • privacy-sensitive work before provider and credential settings are reviewed;
  • performance or hardware-fit claims without testing.
