The control plane for AI you trust in production.

Test, monitor, and protect every prompt, response, and agent in your stack. Ship AI features without crossing your fingers.

Prompt Testing Studio

Write eval suites with assertions. Run them in CI or on-demand against any model. Catch regressions before they reach users.

Live Behavior Monitor

Stream every prompt and response in real-time. Watch for tone drift, latency spikes, and behavioral changes as they happen.

Hallucination & Anomaly Detection

Automated scoring on every response. Flag low-confidence outputs, factual drift, and statistical anomalies automatically.

Security & Injection Defense

Block prompt injection, jailbreak attempts, and data exfiltration in real-time. Full audit trail for compliance.

AI-Powered Insights

Root cause analysis, cost forecasting, and optimization recommendations — generated by AI, grounded in your data.

Agent Control Plane

Define policies for autonomous agents. Enforce step budgets, tool restrictions, and approval gates for high-risk actions.

import { NexisGuard } from 'nexisguards';

const ng = new NexisGuard({
  apiKey: process.env.NG_API_KEY,
  project: 'my-ai-app',
});

// Wrap any LLM call
const response = await ng.wrap(llm.chat(messages));

// nexisguard.config.ts
export default {
  suites: [{
    name: "hallucination-checks",
    assertions: [
      "no unverifiable facts",
      "cite sources when making claims",
      { type: "latency", max: 2000 },
    ]
  }]
}

# .github/workflows/ai-eval.yml
- name: Run NexisGuard evals
  run: npx nexisguards eval --ci

# Fails build if any assertion fails:
# ✓ hallucination-checks (12/12)
# ✗ factual-accuracy (5/6) → blocked

Ship LLM features that don't fail silently.

Catch hallucinations and regressions in CI before they hit users. Monitor production behavior in real-time.

Add AI safely to your existing product.

Protect user data with injection defense. Keep responses on-brand with tone and content guards.

Give autonomous agents real governance.

Define step budgets, tool restrictions, and approval gates. See every decision your agents make.

Latency spike traced to context length

Requests with >8,000 context tokens are averaging 1,840ms — 3.2× baseline. This correlates with the new RAG pipeline activated Tuesday. Truncating to 6k tokens could recover ~61% of the latency.

NexisGuards is the first tool that actually gave us confidence to ship AI features to production. We caught three critical hallucination patterns in staging that would have been catastrophic in prod.

Ship AI you can actually trust.
