Score: 6.5/10 (Innovation: 6, Technical: 7, Documentation: 7, Utility: 6)

Memex is a local-first memory layer for Claude AI that uses offline embeddings to enable semantic search and automatic note-taking, bridging Claude's lack of long-term context. It integrates via MCP (Model Context Protocol) and supports hybrid retrieval, backlinks, and Obsidian compatibility, making Claude smarter about user-specific decisions and context without sending data to external APIs.

Target audience: backend devs, devops, ai-engineers

Repository: https://memex-cli.vercel.app/ · TypeScript · MIT
