What is Noukai?
An AI pipeline builder that lets you create, version, and deploy LLM-powered flows via API.
Noukai is an AI pipeline builder. You compose flows of LLM-powered blocks, version them, and invoke them via a single API URL called a slug.
Core Concepts
Flows
A flow is a directed tree of processing blocks. Each block handles one step: translating text, extracting keywords, classifying sentiment, generating a response.
Blocks
Each block has a processor type:
llm— runs a prompt through an LLM, returns structured outputpassthrough— forwards input unchanged (useful for routing)code— executes custom JavaScript logic
Slugs
Every flow gets a URL built from three slugs:
Once published, anyone with an API key can call this URL to run your flow.
Two Integration Paths
AI-Assisted (Zero-Config)
- Download noukai-prompt.md
- Add it to your project's
CLAUDE.mdor AI context - Tell your AI assistant what pipeline you need
- It builds the flow and inserts the API call into your code
MCP Tools (Full Power)
Configure the Noukai MCP server in your .mcp.json — your AI assistant gets 39 tools for creating, modifying, and publishing flows programmatically.
Manual (Web UI)
Design flows visually at app.noukai.xyz, then call the slug URL from your code.
