LangChain
Agent framework for tool-calling and multi-step LLM workflows.
LangChain is a framework for building applications with LLMs. It provides abstractions for prompt management, chains, agents, and tool use - the building blocks for multi-step AI workflows that interact with external systems.
I use LangChain for building AI agents that need to call tools, query databases, and execute multi-step workflows. It handles the orchestration - deciding which tool to call, managing conversation state, and chaining multiple LLM calls together.
For Barnsley businesses, LangChain powers the agent layer in workflow automation: support ticket triage that queries your CRM, document processing that chains extraction with validation, or internal assistants that look up information across multiple systems.
How I use LangChain for Barnsley businesses
For workflow automation, it orchestrates agents that triage, route, and trigger actions.
For data pipelines, it chains loaders and LLMs for extraction and enrichment.
In B2B SaaS, it builds RAG, agents, and AI workflows into products.
