Every post adds one new concept to the same codebase, so by the end you will have a production-ready chatbot and a solid mental model of how LangChain works.</p> <p>No magic. No abandoned side projects. One app, built in public, one concept at a time.</p> <h2 id="what-we-are-building">What we are building</h2> <p>LangBot is a conversational chatbot that runs in your terminal. Today it will be simple: you type a message, it replies. But every day this week we will add memory, prompt templates, structured output, retrieval, agents, streaming, and more — all in the same codebase.</p>
