The alignment layer for your AI workflows.

Linggen anchors your design decisions directly into your codebase so humans and AI can evolve it without losing its original shape. It bridges the "context gap" by providing persistent memory, a system-wide map, and a library of shared skills.

Traditional AI chat is "blind" to anything you haven't manually copy-pasted. Linggen turns your codebase from a "black box" into a structured system that AI can actually understand:

• 🧠 Design Anchors (Memory): Store architectural decisions, ADRs, and "tribal knowledge" in .linggen/memory as Markdown. AI recalls them via semantic search.
• 📊 System Map (Graph): An Obsidian-like, zoomable dependency graph. Visualize file relationships and "blast radius" before you refactor.
• 🛠️ Shared Library & Skills: Ingest pre-defined skills (e.g., Software Architect, Senior Developer, React Expert) to enforce consistency across projects and teams.
• 🔒 Local-First & Private: All indexing and vector search (via LanceDB) happens on your machine. Your code and embeddings never leave your side.

Why design intent drifts in AI-written code

Install the CLI in seconds and start indexing:

curl -sSL https://linggen.dev/install-cli.sh | bash
sudo linggen install
sudo linggen
cd path/to/project
sudo linggen index

Linggen provides skills server by default and a optional Model Context Protocol (MCP) server that connects your local "brain" to MCP-enabled IDEs like Cursor, Zed, or Claude code.

Install linggen extension in VSCODE or Cursor, that will inject linggen into your AI.

"Call Linggen SKILLS, find out how project-sender sends out messages, and summarize the architecture."

"Using Linggen's default skills, refactor this component to follow clean code standards and our existing patterns."

"Check Linggen memory for any ADRs related to our database choice before suggesting a schema change."

"Use the 'Senior Developer' skill for this task and propose a safe refactor plan with small, reviewable commits."
