NKJ is a library for identifying JIS X 0213 characters.

The app provides a command-line interface (CLI) to an Ollama AI model, allowing users to engage in text-based conversations and generate human-like responses. Users can import data from local files or web pages, which are then processed through three different modes: fully importing the content into the conversation context, summarizing the information for concise reference, or storing it in an embedding vector database for later retrieval based on the conversation.

A production-ready, agent-first Ruby client for the Ollama API with schema validation, bounded retries, and explicit safety defaults. Includes a minimal agent layer (Ollama::Agent::Planner for deterministic /api/generate, and Ollama::Agent::Executor for stateful /api/chat tool loops with disciplined, observer-only streaming). Not a chatbot UI and not a promise of full Ollama endpoint coverage.
