OmniBox: Open-Source AI Knowledge Base & Agent

OmniBox (小黑) is an open-source, all-in-one AI knowledge management app that captures content from your everyday channels—forwarded WeChat/QQ messages, quick notes, browser clips, and RSS feeds—then parses, transcribes, and OCRs it into editable, searchable knowledge you can query, write from, and act on with an AI agent. It's built for individuals, researchers, and knowledge workers drowning in bookmarks and scattered files who want a single closed loop from capture to creation. Its main differentiator is being Apache-2.0 open source and fully self-hostable (down to your own server, storage, and local Ollama models), with MCP/Skill access from agents like Claude Code and Codex.
