PaperClip is a Chrome extension that leverages AI to aid in the review and memorization of scientific papers. It allows users to highlight text and generate detailed notes, which can be easily retrieved via a similarity search. This tool is particularly helpful for researchers and students working in machine learning, computer vision, and natural language processing, enabling them to efficiently manage and recall crucial details from their readings.

GraphSignal is an AI-driven graph intelligence platform that seamlessly integrates vector-based embeddings and knowledge graph structures. Users can connect their data sources, automatically generate embeddings using built-in or custom models, and index nodes and edges for real-time semantic querying. The platform offers RESTful APIs and SDKs to perform advanced graph analytics, similarity searches, recommendations, and question-answering tasks across connected data. Its dynamic visualization tools help teams explore relationships and derive actionable insights from complex networks.

cpp-langchain implements core features from the LangChain ecosystem in C++. Developers can wrap calls to large language models, define prompt templates, assemble chains, and orchestrate agents that call external tools or APIs. It includes memory modules for maintaining conversational state, embeddings support for similarity search, and vector database integrations. The modular design lets you customize each component—LLM clients, prompt strategies, memory backends, and toolkits—to suit specific use cases. By providing a header-only library and CMake support, cpp-langchain simplifies compiling native AI applications across Windows, Linux, and macOS platforms without requiring Python runtimes.
