LangChain tutorials, crowdsourced by a Seoul collective
Open-tutorial Jupyter notebooks for LangChain and LangGraph, maintained by a large Seoul-based contributor group and aimed at a global audience.

What it does
This repository is a collection of notebook files that teach LangChain and LangGraph through practical examples. Born from a Korean-language predecessor, it has been reopened by the Seoul LangChain community for international users. Every notebook is expected to run on Google Colab and is reviewed for compatibility across Mac, Windows, and Linux.
The interesting bit
Instead of a single author, the project runs like an open-source journal: contributors submit notebook pull requests, at least two reviewers check code quality and cross-platform execution, and a proofreading team cleans up typos and citations. That is a heavier editorial process than most community tutorials bother with.
Key highlights
- Community-maintained curriculum with a large, named contributor base.
- Targets recent LangChain and LangGraph releases, though the README does not enumerate specific versions or topics.
- Requires Colab execution and cross-platform compatibility as submission criteria.
- Offers Korean and English templates for contributors.
- MIT-licensed.
Caveats
- The README displays an “experimental” status badge, so completeness and stability are unclear.
- No table of contents or topic list is visible in the README; you have to browse the repository to see what is actually covered.
Verdict
Useful if you learn best by running notebooks and want community-tested examples. Look elsewhere if you need a stable, fully scoped syllabus or a quick reference guide.
