About AnythingLLM
AnythingLLM is a local first AI application that enables users to chat with their documents using any large language model (LLM), local or cloud hosted. It runs as a self hosted service—by default in Docker—and provides a complete interface for document ingestion, agent orchestration, multi user access, and workflow automation without requiring external cloud dependencies. The project lives in the local AI and AI interaction ecosystem, targeting users who want full control over their data and model selection.

About AionUi
AionUi is an open source, cross platform Cowork application that puts AI agents to work alongside the user on their own computer. It is written in TypeScript and released under the Apache 2.0 license, and it lives in the AI agent and chat tooling ecosystem alongside the command line agents it is built to host. Rather than acting as a plain chat client, it runs a built in agent engine that can read and write files, search the web, generate images, and call Model Context Protocol tools, while showing the user every action the agent takes and keeping approval in the user's hands.
