RedNote is an open-source AI agent built with Python and LangChain that lets users input raw text or document files for automated processing. It leverages large language models to generate concise summaries, extract action items, identify key insights, and categorize information. The agent maintains context across sessions using built-in memory storage, supporting cumulative knowledge building. Users can pose follow-up questions to refine or expand summaries, and the system can export results as structured markdown files. RedNote’s modular architecture and plugin system enable integration with external services like Notion or Obsidian. This end-to-end solution enhances note-taking, research synthesis, and knowledge management for individuals and teams.
