Mnemos is a free AI search tool designed for local memory management of AI agents. It enhances the capabilities of AI models like Claude Code by allowing them to access and cite project-specific knowledge such as architectural decision records (ADRs), design documents, and source code. This tool operates entirely on the user's machine without the need for external databases or dependencies, ensuring data privacy and security. Users can quickly set up Mnemos by indexing their project files, enabling efficient searches that return precise citations for any inquiry.

The software features a straightforward command-line interface that facilitates project setup, file indexing, and search operations. Mnemos supports both lexical and semantic search capabilities, allowing users to retrieve information based on keyword and natural language queries. Additionally, it provides mechanisms for managing memory, including capturing notes and managing document states, making it a versatile solution for maintaining an organized knowledge base within projects.
