Claude-Mem is a persistent memory plugin designed for Claude Code, allowing it to maintain context across sessions. It captures tool usage observations and generates summaries, enabling users to retain knowledge about their projects even after disconnecting. Users can start a new session by installing the plugin through simple terminal commands, and context from previous interactions will automatically be integrated into the new session. The system features five lifecycle hooks to manage memory efficiently, including session start and end. It employs a three-layer workflow for intelligent memory search, allowing users to query their history and retrieve full details only when necessary, optimizing token usage. Key functionalities include a web viewer UI for real-time memory streams, privacy controls to exclude sensitive information, and skill-based searches for ease of access. The integration with various messaging platforms like Telegram and Discord enhances its utility for users. Installation requires Node.js, Claude Code, and Bun, all of which can be auto-installed. Configuration settings are stored in a JSON file, allowing adjustments to AI models, ports, and context management. For troubleshooting, the system can automatically diagnose issues based on user input. The project is open-source under the AGPL-3.0 license, promoting free use and modification while ensuring that modifications remain accessible.
