Protect Your Client Retainers From Silent AI Failures.

🛡️ Built for Client Deliverables

Keep client retainers running smoothly without spending hours building custom monitoring scripts.

🚨 Instant Client-Risk Alerts

Catch empty blocks, token limits, and LLM "no-apologies" refusals before your client notices a dip.

⏱️ 5-minute Setup

Paste a single webhook at the end of your AI workflow (Make, Zapier, n8n etc). No extra database required.
