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.
| Platform | Windows 10 and 11 |
|---|---|
| Licence | MIT — open source, audit every line |
| Price | Free. No paid tier, no ads, no telemetry |
| Account | None. Unlicensed installs run as Personal Use, fully functional |
| Network | Binds to 127.0.0.1 only. Works fully offline |
| AI engine | Six selectable local GGUF models, or bring your own |
Every monitor shows you a CPU line.
Almost none of them tell you what it means. AROK splits the job in two — maths finds the signal, language explains it — and detection is never delegated to the model.
It explains, it doesn't just graph
A local model turns deterministic findings into a sentence you can act on: "Chrome has been climbing for 20 minutes and is now using 40% CPU — unusual for this time of day." Because detection happens before the model sees anything, the finding is exact. The AI only narrates.
100% local and private
Metrics, history and AI inference all stay on your machine, and it works fully offline. No account, no telemetry, no ads, nothing phoning home on a schedule you don't control.
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. There is no upgrade prompt, because there is nothing to upgrade to.
Nine tabs. One story about your PC.
Each tab answers a different question, and every one can hand its findings to the narrator.
System overview — CPU, memory, disk, processes and network throughput at a glance, with the AI Pulse summary alongside.
What's running, what it's costing you, and which process caused the spike you just saw.
A live world map of every external connection, resolved geographically and scored by transparent heuristics.
Windows services, their state, and what changed since you last looked.
Temp-file clearing, a conservative registry cleaner, and a checksum-verified Tron launcher.
Resource trends with spike-cause markers. Click a marker to pin the moment and drill into the snapshot behind it.
Anomaly findings, a plain-English story of your system, and a chat panel wired to your local model.
Diagnosis-led hardware recommendations from your own telemetry, matched to your socket and memory generation.
Model selection, thresholds, licensing and the demo-mode switch.
Auto-detects when you're playing and steps out of the way. Reachable from every tab, not buried in settings.
Findings you can open up.
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 and teach the baseline.
Analytics with spike causes
- →Resource-trend graphs annotated 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, and one-click optimisation recommendations.
- →A chat panel wired straight to your local model — ask it about your own machine.
SMART sensor watch
- →Drive health, wear levels and temperatures feed both alerting and upgrade advice.
- →A failing disk tells you to back up before it dies, not after.
Safe, guided cleanup
- →Temp-file cleaner, plus a conservative registry cleaner that takes a restore point and a .reg backup first.
- →Checksum-verified Tron launcher for the heavier jobs.
Upgrade Advisor
- →Recommendations led by diagnosis from your own telemetry — matched to your CPU socket and memory generation, so nothing incompatible is suggested.
- →Affiliate-funded and FTC-disclosed. This tab is the entire business model.
Real local AI. Your choice of model.
Pick 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 already on your disk. After download, narration and chat run entirely offline.
Local model
Private, offline, free. Downloaded once, then it never touches the network again. This is the default and the recommendation.
Anthropic Cloud
Optional. Bring your own API key if you want a larger model doing the narration. Off unless you explicitly turn it on.
Deterministic templates
No AI configured at all? Narration falls back to written templates and the app works exactly as before. Detection never depended on the model in the first place.
A monitor with this much access had better be careful.
| Binding | The server binds to 127.0.0.1 only. Nothing is exposed to your network — not to your router, not to the machine next to you. |
|---|---|
| Rebinding | Localhost Host and Origin checks block DNS rebinding; per-session tokens block CSRF from malicious pages open in another tab. |
| Demo mode | Simulates control actions — kill process, block IP, stop service — instead of executing them. Look around safely before handing it real control. |
| Licensing | Offline Ed25519. No activation server to call, and no crippled tier. |
| Source | MIT. Audit every line yourself rather than taking the above on faith. |

Answered plainly.
Yes. AROK is open source under 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.
No. Detection, history and local-AI narration all run offline. The internet is only used if you choose to download a model, refresh upgrade pricing, or enable optional cloud narration with your own API key.
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. Nothing about your machine is transmitted anywhere, because there is nowhere for it to go.
