The system monitor that explains itself.
AROK watches your Windows PC, detects anomalies deterministically, and uses a local AI to narrate what’s happening in plain English — 100% on your machine. No cloud, no telemetry, no account.
Free · Open source (MIT) · Windows 10/11 · No account · No telemetry
Why AROK?
It explains, it doesn’t just graph
Every monitor shows you a CPU line. AROK’s local AI turns deterministic findings into plain English: “Chrome has been climbing for 20 minutes and is now using 40% CPU — unusual for this time of day.” Detection is never delegated to the model, so it’s exact; the AI only narrates.
100% local and private
Metrics, history, and AI inference all stay on your machine. Works fully offline. Open source (MIT), no account, no telemetry, no ads.
Free — for real
Funded only by optional, clearly-disclosed Amazon affiliate links in the Hardware Upgrades tab. If you never open that tab, AROK costs nothing and sells nothing.
Nine tabs. One story about your PC.
Dashboard · Processes · Network · Services · Cleanup · Analytics · AI Insights · Upgrades · Settings — plus a global Gaming mode with auto-detect.
A live world map of your network
Every external connection resolved geographically, animated, and scored with transparent, deterministic heuristics. Click Investigate on any endpoint to see exactly why it was flagged — or mark it safe.
Analytics with spike causes
Resource-trend graphs with spike-cause markers. Click a marker to pin that moment and drill into the per-process snapshot that caused it.
AI Insights & chat
Anomaly findings, a plain-English story of your system, one-click optimization recommendations, and a chat panel wired straight to your local model.
SMART sensor watch
Drive health, wear and temperatures feed both alerting and upgrade advice. A failing disk tells you to back up before it dies.
Safe, guided cleanup
Temp-file cleaner, a conservative registry cleaner (restore point + .reg backup first), and a checksum-verified Tron launcher.
Upgrade Advisor
Diagnosis-led recommendations from your own telemetry, matched to your CPU socket and memory generation — nothing incompatible is ever suggested. Affiliate-funded, FTC-disclosed.
Real local AI. Your choice of model.
Pick your model in-app from a curated menu of six open-source GGUFs — Qwen 2.5 1.5B through Mistral 7B, each listed with parameter count and download size — or point AROK at a GGUF you already have on disk. After download, narration and chat run entirely offline.
Engine priority
1. Local model — private, offline, free.
2. Anthropic Cloud — optional, bring your own key.
3. Deterministic templates — no AI configured? Narration falls back to templates. The app always works.
Built paranoid, on purpose.
- The server binds to 127.0.0.1 only — nothing is exposed to your network.
- Localhost Host/Origin checks block DNS rebinding; per-session tokens block CSRF from malicious pages.
- Demo mode simulates control actions (kill process, block IP, stop service) instead of executing them.
- Offline Ed25519 licensing — unlicensed installs run as Personal Use with full functionality.
- MIT open source: audit every line yourself on GitHub.
Questions, answered.
Is it really free?
Yes. AROK is open source (MIT) with no paid tiers, no ads, and no telemetry. It’s funded only by optional, clearly-disclosed Amazon affiliate links inside the Hardware Upgrades tab. If you never open that tab, AROK costs nothing and sells nothing.
Does it need an internet connection?
No. Detection, history, and local-AI narration all run offline. Internet is only used if you choose to download a model, refresh upgrade pricing, or enable optional cloud narration with your own API key.
Is my data safe?
Everything stays on your machine: metrics, history, and AI inference. The server binds to localhost only, and there is no account and no telemetry of any kind.
What does it run on?
Windows 10 and 11. Grab the installer from GitHub Releases and run it — updates download quietly in the background and apply with one click.
