Show HN: Linggen – A local-first memory layer for your AI (Cursor, Zed, Claude)

Summary

Linggen: Stop re-explaining to AI. The free and local app for your AI’s memory. Linggen indexes your codebases and tribal knowledge so your AI (Cursor, Zed, Claude, etc.) can actually understand your architecture, cross-project dependencies, and long-term decisions. Website • VS Code Extension • Documentation 🌀 Why Linggen? Traditional AI chat is "blind" to anything you haven't manually copy-pasted. Linggen bridges this "context gap" by providing: 🧠 Persistent Memory: Store architectural decisions in .linggen/memory as Markdown. AI recalls them via semantic search. Store architectural decisions in as Markdown. AI recalls them via semantic search. 🌐 Cross-Project Intelligence: Work on Project A while your AI learns design patterns or auth logic from Project B. Work on Project A while your AI learns design patterns or auth logic from Project B. 📊 System Map (Graph): Visualize file dependencies and "blast radius" before you refactor. Visualize file dependencies and "blast radius" before you refactor. 🔒 Local-First & Private: All indexing and vector search (via LanceDB) happens on your machine. Your code and embeddings never leave your side. No accounts required. 🚀 Quick Start (macOS) Install the CLI in seconds and start indexing: curl -sSL https://linggen.dev/install-cli.sh | bash linggen start linggen index . Windows & Linux support coming soon. 💬 How to use it with your AI Once Linggen is running and your project is indexed, simply talk to your MCP-enabled IDE (like Cursor or Zed): "Call Linggen MCP, find out how project-sender sends out messages, and ingest it." "Call Linggen MCP, load memory from Project-B, learn its code style and design pattern." "Load memory from Linggen, find out what is the goal of this piece of code." 📂 The Linggen Ecosystem linggen: The core engine and CLI runtime.
