LangChain
Tools for composing language-model applications, retrieval, and data-aware workflows.
What it is
LangChain provides abstractions for model calls, retrieval, tools, and multi-step language workflows.
How I learned it
I learned its core patterns while exploring retrieval-augmented application workflows.
How I use it
I use it to organize retrieval and language-model interactions around application data.
Concepts I work with
- Chains
- Retrievers
- Prompt composition
- Structured output
What I learned
The application data flow should remain understandable even when model orchestration grows.
Applied experience
Projects using LangChain
I haven't published a project using LangChain yet — it's something I use in work that isn't shareable, or that I'm still building.
