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. FREE FEATURES • Real-time token and cost monitoring • Activity feed with safety verdicts and insights • Firewall mode (pause/block suspicious requests) • Conversation capture and 3-day history with search • Context handoff (copy conversation summary for a new chat) • Weekly cost report card • Works across multiple AI platforms PRO FEATURES (Lifetime Founding Membership — $79 one-time) • Unlimited conversation history (no time limit) • Full-text search across all captured conversations • CSV and Markdown export • Auto-approve rules for known-safe patterns • Session budget hard-stops • Direct line to the developer • Every future feature included forever 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.
