Catalyst
🚀 Catalyst is a C# Natural Language Processing library built for speed. Inspired by spaCy's design, it brings pre-trained models, out-of-the box support for training word and document embeddings, and flexible entity recognition models. (by curiosity-ai)
Project mention: Catalyst VS Panlingo - a user suggested alternative | libhunt.com/r/curiosity-ai/catalyst | 2025-02-03 -
LangChain
C# implementation of LangChain. We try to be as close to the original as possible in terms of abstractions, but are open to new entities. (by tryAGI)
Project mention: A simple approach for ingesting documents using .NET for a simple Retrieval Augmented Generation (RAG) system | dev.to | 2025-02-16In this case, I have opted to experiment with LangChain .NET project We are using MarkdownHeaderTextSplitter and CharacterTextSplitter from LangChain .NET.
