How it works

Install. Watch. Control.

IcyHat monitors every AI request your browser makes — silently logging, smartly alerting, or actively blocking based on your rules.

Step 01
📦
Install the extension
One click from the Chrome Web Store. IcyHat activates automatically on every AI platform — Claude, ChatGPT, Gemini, Copilot, and more.
Step 02
👁️
See everything
A discreet panel shows every request in real time. Token counts, cost estimates, model info, and what the AI is actually doing — all visible at a glance.
Step 03
🧊
Freeze anything suspicious
Set thresholds or go full firewall mode. When something looks wrong — runaway loops, massive token burns, unauthorized tool use — IcyHat freezes the request until you decide.
Three modes

Your level of control

From passive tracking to full lockdown. Choose what fits your workflow.

⚡
Monitor
Smart thresholds. Normal chat flows through silently. You only see alerts when something's unusual — big requests, high cost, tool use, or rapid-fire loops.
💰
Token Meter
Pure tracking. Nothing ever blocked. Just a clean dashboard showing exactly how many tokens you're burning and what it's costing — across every platform.
🛡️
Firewall
Full lockdown. Every AI request paused for your review. Allow or block each one individually. Maximum control for high-stakes agent work.
Features

Everything you need to
know what's happening

Built for people who use AI every day and want to understand what's going on under the hood.

📊
Token & cost tracking
Per-message and session totals. Model-aware pricing for 17+ models across Anthropic, OpenAI, and Google.
🔍
Real-time activity feed
See every request as it happens. Grouped by severity — safe, flagged, and paused — so you focus on what matters.
🛠️
Tool use detection
Know when AI is calling functions, searching the web, or executing code — not just chatting.
🚨
Runaway loop protection
Automatic detection of rapid-fire request bursts. Catches agent loops before they burn through your quota.
📈
Daily message gauge
Visual fuel gauge shows how much of your daily rate limit you've used. Know when to pace yourself.
💡
Plain English, not jargon
Every alert, badge, and description written for humans. No "API request blocked" — just clear explanations of what's happening.
🎯
Smart verdicts
Four-level assessment on every request: Safe, Routine, Caution, Warning. Know at a glance whether to worry.
🔒
100% local
Everything runs in your browser. No data sent to our servers. No accounts required. Your AI activity stays yours.
