The Language
for Knowledge Pipelines

Harnessing LLMs for critical knowledge work often means wrestling with complex glue code and mega-prompts. This makes building AI applications slow, expensive, and unreliable.

Pipelex is a declarative language to define and execute LLM-driven knowledge pipelines, delivering reliable, structured results.

The core framework is an open-source Python library, available on GitHub.

Simply build reliable AI applications

Pipe-based structure
 

The Pipelex language uses pipelines, or "pipes", each capable of integrating different LLMs to process knowledge.
Pipes consistently deliver structured, predictable outputs at each stage.

User-friendly syntax
 

Pipelex employs a clear easy to read syntax, enabling developers to intuitively define workflows in a narrative-like manner.
It facilitates
collaboration between business professionals, developers, and AI Agents.

Modular Building Blocks

Our pipelines work like modular building blocks, assembling pipes sequentially, in parallel, and by calling sub-pipes.


It's intuitive and powerful plug-and-play for knowledge in, knowledge out.

Open-Source • API • MCP
 

Pipelex is meant to integrate into any software and automation framework.
It's an
open-source Python library, with a hosted API launching soon, along with an MCP server enabling AI Agents to run pipelines like any other tool.

Pipelex combines the reliability and replicability of software with the understanding and creativity of AI


  Without Pipelex​​​

 

Custom glue code & mega-prompts wasting hours

 

Prompts, business rules, and SDK calls get hopelessly tangled

 

Endless prompt-tweaking is a time sink and barely gets you to 80% reliability
 

One model change? Outputs drift and brittle tests collapse
 

Each new AI feature feels like rebuilding from scratch


  With Pipelex​​​

 

Declarative pipelines for knowledge workflows

Business logic lives in pipes / Python stays lean and testable

Every step emits typed, version-controlled outputs you can trust

Swap in cheaper or faster LLMs per pipe while keeping guard-railed quality

Plug-in community pipes speed new features: no reinvention needed
