THE NERVOUS SYSTEM OF AI
The Nervous System for AI Streams.
NeuroLink is the signal layer for the AI nervous system, connecting live streams of tokens, data, tools, and context through pluggable connectors.
npm install @juspay/neurolinkWorks with leading AI providers
STREAMS
Thirteen sources.
One stream.
Every type of AI intelligence flows through the same stream layer. Pick your sources. Shape the signal. Deliver to any organ.
THE FLOW
Six stages.
One continuous flow.
Every request follows the same flow. Hover a stage to see how it works.
RAG retrieval, memory lookup, and file processing merge into the prompt before the model fires.
const result = await link.generate({
prompt: query,
rag: { files: ['./docs/guide.md'] },
memory: { enabled: true },
});CONNECTORS
Organs built on the stream layer.
Every application built on NeuroLink is an organ. It connects to the vascular layer and opens a gateway — a new way for people to access and experience AI.
Automatic
Consumer analysis and operations hub. Routes order data and payment context through the signal layer to surface risk signals and recommendations.
Consumer control · Operations intelligence
Tara
Self-evolving AI assistant. Receives Slack events, uses MCP tools to answer from code and docs, and improves itself through task loops.
Engineering assistance · Self-improvement
Yama
Code review judge. Streams PR diffs through the signal layer, applies rule-driven analysis, and enforces quality gates before merge.
Code quality · Automated governance
05 — DEVELOPER EXPERIENCE
Developer-first TypeScript AI SDK experience

import { NeuroLink } from "@juspay/neurolink";
const ai = new NeuroLink({
provider: "anthropic",
model: "claude-sonnet-4-20250514",
});
const result = await ai.generate({
prompt: "Analyze this codebase",
tools: ["github", "readFile"],
});BUILT AT SCALE
Production-tested AI SDK from Juspay
NeuroLink was extracted from production systems at Juspay, where it powers the company's AI workloads.
Extracted from Production
Built inside Juspay, a fintech company, and extracted from its production systems.
193K+ Lines of TypeScript
447 source files. 269 tests. Deep investment in a comprehensive, type-safe SDK.
MIT Open Source — Free Forever
No vendor lock-in, no usage fees. You only pay for the AI provider API calls you make.
One Package. Everything Included.
Providers + RAG + agents + voice + workflows + MCP — in a single npm install. No assembly required.
From the team
Built by engineers, for engineers
NeuroLink powers AI workloads at Juspay. Here's what the teams building with it have to say.
NeuroLink lets us switch between OpenAI, Anthropic, and Gemini with a single config change. We went from managing three separate SDKs to one unified interface — deployment time dropped significantly.
Engineering Team
Juspay — AI Platform
The RAG workflow is incredibly simple. We pass files directly to generate() and NeuroLink handles chunking, embedding, and retrieval automatically. What used to take a week of integration work now takes an afternoon.
Backend Engineer
Juspay — Developer Experience
MCP integration with ToolRouter and RequestBatcher solved our tool sprawl problem. 58+ servers through one registry, with intelligent caching. No other TypeScript SDK offers this level of MCP optimization.
