Show HN: Memex, Claude memory via local RAG (MCP, offline embeddings) (memex-cli.vercel.app)

A new tool called Memex has been launched, enhancing Claude's capabilities by providing it with a persistent memory system that operates entirely offline. This innovative solution allows users to save insights and data directly on their machines, ensuring privacy as no information is sent to the cloud or stored on external servers. Memex integrates seamlessly with existing Obsidian vaults and uses a local SQLite database to manage embeddings, relying on Hugging Face's transformers for its operations. Users can easily install Memex and start utilizing it within minutes. The significance of Memex lies in its focus on data privacy and developer autonomy, making it particularly appealing to those wary of cloud-based solutions. By allowing Claude to reference past notes and surface relevant information during conversations automatically, Memex creates a powerful second brain for its users. This tool could transform how professionals interact with AI, facilitating more informed discussions and decision-making by retaining context across multiple interactions without compromising data security.
