Modules

  • Processes Every running process with its resource use, family tree and details, and how to end or reprioritize one safely.
  • Network and ports Listening ports, live connections matched to their processes, the world map, and firewall rules you can add and remove.
  • CPU and memory Per-core load, memory and swap over time, load average, and temperature and fan sensors where your system exposes them.
  • Storage Scan a disk or folder, explore it as a treemap, find large and duplicate files, and move what you don't need to the Trash.
  • AI agent Choose a local or cloud model, store API keys securely, and ask Sentinel to investigate and fix things in plain English.

Trust and privacy

  • How the agent stays safe A plain-language account of plan, confirm and execute, and the rules that keep the agent from doing anything you didn't approve.
  • Privacy What stays on your computer, the few reasons Sentinel uses the network, and exactly what a cloud AI provider receives.
