[Website](https://linggen.dev) • [VS Code Extension](https://marketplace.visualstudio.com/items?itemName=linggen.linggen-vscode) • [Documentation](https://linggen.dev/docs) --- ## 🌀 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. - **🌐 Cross-Project Intelligence:** 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. - **🔒 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 & Linux) Install the CLI in seconds and start indexing: ```bash curl -sSL https://linggen.dev/install-cli.sh | bash linggen start linggen index . ``` On Linux, you can set up the background server and systemd service after CLI installation: ```bash sudo linggen install ``` --- ## 💬 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](https://github.com/linggen/linggen):** The core engine and CLI runtime. - **[linggen-vscode](https://github.com/linggen/linggen-vscode):** VS Code extension for Graph View and automatic MCP setup. - **[linggensite](https://github.com/linggen/linggensite):** (This Repo) The landing page and documentation site. - **linggen:** The core engine, CLI, and published releases. --- ## 📜 License & Support Linggen is open-source under the **[MIT License](LICENSE)**. - **100% Free for Individuals:** Use it for all your personal and open-source projects. - **Local-First:** Your code and your "memory" never leave your machine. - **Commercial Support:** If you are a team (5+ users) or a company using Linggen in a professional environment, we ask that you support the project's development by purchasing a **Commercial License**. For more details on future enterprise features (SSO, Team Sync, RBAC), visit our [Pricing Page](https://linggen.dev/pricing) or [get in touch via email](mailto:linggen77@gmail.com). --- ## 🗺️ Roadmap - [x] **Core Engine:** Local indexing and semantic search (LanceDB). - [x] **MCP Support:** Use with Cursor, Zed, and Claude. - [x] **Visual System Map:** Graph visualization of your codebase. - [ ] **Team Memory Sync:** Share architectural decisions across your team. - [ ] **Deep Integration:** More IDEs and specialized agents. - [ ] **Windows Support:** Bringing the local engine to more platforms.
