AI Compliance Audit Logger
Colorado AI Act is live. EU AI Act hits August 2. Your AI system needs audit logs by yesterday.
The Problem
Both the EU AI Act and Colorado SB 24-205 require companies to maintain audit logs of AI system decisions and outputs, accessible to regulators within 72 hours. Most Next.js apps have zero logging of their LLM interactions.
The Solution
A serverless Next.js edge middleware that automatically intercepts all LLM API calls, extracts required metadata (model, prompt hash, completion hash, timestamp, user context), and writes cryptographically signed audit records to the client's own storage bucket — never to VektorIndex servers.
Why You Have No Choice
You cannot pass a regulatory audit without these logs. The EU AI Act explicitly requires them. The Colorado AI Act requires them for high-risk AI decisions. Building this from scratch takes 2–3 weeks minimum.

This is what you'll drop into your codebase. The full package includes all configuration options and integrations.
// audit-logger.middleware.ts
import { withAuditLog } from './audit-logger.middleware'
export const POST = withAuditLog(
async (req: Request) => {
// Your existing AI API route — unchanged
const response = await openai.chat.completions.create({ ... })
return Response.json(response)
},
{
storage: 'supabase', // or 'r2', 's3'
tableName: 'ai_audit_logs',
hashPrompts: true, // SHA-256 hash, never stores raw prompts
includeUserContext: true,
complianceMode: 'eu-ai-act' // or 'colorado', 'both'
}
