Why NeuroLink? Switch providers with a single parameter change, leverage 64+ built-in tools and MCP servers, deploy with confidence using enterprise features like Redis memory and multi-provider failover, and optimize costs automatically with intelligent routing. Use it via our professional CLI or TypeScript SDK—whichever fits your workflow.

Where we're headed: We're building for the future of AI—edge-first execution and continuous streaming architectures that make AI practically free and universally available. Read our vision →

Enterprise Security: Human-in-the-Loop (HITL)

NeuroLink includes a production-ready HITL system for regulated industries and high-stakes AI operations:

Capability	Description	Use Case
Tool Approval Workflows	Require human approval before AI executes sensitive tools	Financial transactions, data modifications
Output Validation	Route AI outputs through human review pipelines	Medical diagnosis, legal documents
Confidence Thresholds	Automatically trigger human review below confidence level	Critical business decisions
Complete Audit Trail	Full audit logging for compliance (HIPAA, SOC2, GDPR)	Regulated industries

import { NeuroLink } from "@juspay/neurolink";

const neurolink = new NeuroLink({
  hitl: {
    enabled: true,
    requireApproval: ["writeFile", "executeCode", "sendEmail"],
    confidenceThreshold: 0.85,
    reviewCallback: async (action, context) => {
      // Custom review logic - integrate with your approval system
      return await yourApprovalSystem.requestReview(action);
    },
  },
});

// AI pauses for human approval before executing sensitive tools
const result = await neurolink.generate({
  input: { text: "Send quarterly report to stakeholders" },
});
