Really excited to see LangChain moving really fast in this space. They turn your favorite Llm into a real boy that can do real work.

Some "agents" in their vernacular that I've built.

* A reminder system that can take a completely free-form English description and turn it into a precise date and time and schedule it with an external scheduler.

* A tool that can take math either in English or ascii like y = 2x^2 + ln(x) and turn it into rendered LaTeX.

* A line editor that let's you ingest Word documents and suggests edits for specific sections.

* A chess engine.

Like it's crazy at just how trivial all this stuff is to build.




I share your enthusiasm for LangChain (as well as LlamaIndex). I don’t remember being as obsessed by any new technology. I am writing a book on the subject [1] but to be honest the documentation and available examples are so very good, that my book has turned into just a write up of my own little projects.

I agree that some things really are trivial to implement and I think this opens the door to non-programmers who know a little Python or JavaScipt to scratch their own itches and build highly personalized systems.

That's funny...I actually just bought your book because I have a bone to pick with the documentation. It's good at explaining stuff, but I feel it fails to show how some of the parts work together. It would be immediately more obvious if there were just full examples rather than partial ones.

Thanks for writing this.


Thanks for the kind comments! The final version should be available in a day or two.


These examples are great, but the chess engine sounds specially interesting and can't think of how I'd do it with langchain. Do you have a git link or something written down, on how you accomplished this?


> Some "agents" in their vernacular that I've built.

Are any of those open source / are they on Github? Could you link it?
