How AI describes Arcjet

Arcjet is a runtime policy engine for AI features that authorizes tools and enforces decisions inline in your application by evaluating identity, session, route, and request data before AI tools execute. It provides AI endpoint abuse protection with per-user and per-org budgets, spam and trial abuse prevention, and PII detection to prevent personal data leaks into model prompts, logs, and external tools. It offers built-in security features like cost and quota management, bot protection, and PII redaction, and integrates with frameworks like Next.js via an SDK (e.g., npm install @arcjet/next) to block attacks before they reach AI endpoints.
