About IcyHat — AI Cost Monitor & Agent Firewall
Know what your AI is doing before it costs you.
IcyHat monitors your AI platform usage in real time — tracking every request, estimating costs, and analyzing agent behavior. See exactly how many tokens you're spending, catch runaway conversations, and take control of AI agent actions.
HOW IT WORKS
IcyHat adds a lightweight sidebar to your AI platforms. It shows:
• Real-time token and cost tracking per session and per week
• Message count with daily budget gauge
• Activity feed showing every request with safety verdicts
• Conversation history with full-text search and export
• Context handoff — generate a summary to paste into a new chat
• Shareable weekly cost report (one-click PNG)
FIREWALL MODE
Pause suspicious requests before they execute. IcyHat detects unusual patterns — spiraling conversations, excessive tool use, rapid-fire requests — and lets you approve or block them.
PRIVACY FIRST
All monitoring happens locally in your browser. No data leaves your device. No accounts, no cloud sync, no tracking. Your conversations and usage data are yours alone.

IMPORTANT NOTES
Token counts and cost estimates are approximations based on request analysis. Actual usage may vary. Platform updates may temporarily affect monitoring accuracy. IcyHat actively maintains compatibility but cannot guarantee uninterrupted service on third-party platforms.
